Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Fig. 1 is a flowchart of an embodiment of a method for verifying a generated virtual road guiding identifier according to the present invention, and as shown in fig. 1, the method for verifying a generated virtual road guiding identifier according to the embodiment of the present invention includes the following steps:
s101: connecting every two adjacent virtual road indicating marks to determine a first connecting track; the virtual road directing identifier is in a virtual activity scene and is used for simulating design parameters of the entity road directing identifier; the virtual activity scene is a virtual model established according to preset activity scene data.
Specifically, the device connects every two adjacent virtual road indication marks to determine a first connecting line track; the virtual road directing identifier is in a virtual activity scene and is used for simulating design parameters of the entity road directing identifier; the virtual activity scene is a virtual model established according to preset activity scene data. The apparatus may be a computer device, e.g. a server, performing the above method. The method may run in a Unity environment.
The server can operate the simulation system to further acquire the virtual activity scene, and can also acquire the virtual activity scene from the simulation system operated in other equipment by establishing a connection relationship with other equipment.
The virtual model is a visual model simulating a real activity scene.
Fig. 2 is a screenshot of a virtual activity scene according to an embodiment of the present invention.
The virtual activity scenario may be developed by Unity. The virtual object models in the virtual activity scene all have three-dimensional geographic position coordinates; the preset activity scene data comprises geographic environment data and planning and designing data. Geographic environment data can be acquired by aerial photography of an unmanned aerial vehicle or photographing of a handheld camera, and planning design data can be acquired from an OB (Overlay Book) picture which is a special electronic drawing for active operation design.
Referring to fig. 2, the virtual guidepost identifies a guideboard labeled "evacuation lane" as in fig. 2. The virtual routing identifier includes location and indicating information that can be displayed in fig. 2 so that design parameters of the physical routing identifier can be modeled.
As shown in fig. 2, the position is a three-dimensional geographic position coordinate of the guidepost, and the indication information includes identification indication direction information of the guidepost.
Fig. 3 is a schematic diagram illustrating a first connection track according to an embodiment of the present invention, and as shown in fig. 3, a 1-d 1 respectively represent virtual road indicators, and a connection connecting a 1-d 1 is the first connection track.
S102: comparing the first connecting track with the second connecting track, and verifying the position of the virtual road indicating mark according to the comparison result; wherein the second connecting line track is a streamline track in the virtual live view.
Specifically, the device compares the first connecting track with the second connecting track, and verifies the position of the virtual guide path identifier according to the comparison result; and the second connecting line track is a streamline track in the virtual activity scene. Fig. 4 is a schematic diagram illustrating a second connection trace according to the embodiment of the present invention, where as shown in fig. 4, a 2-d 2 respectively represent inflection points of a streamline, and a connection line connecting a 2-d 2 is the second connection trace.
It should be noted that the second connecting trajectory, that is, the streamline trajectory, is created in the virtual activity scene in advance, and then the streamline inflection point is determined according to the streamline trajectory.
The first connecting track, namely the virtual road indicating identification track, is firstly generated, and then the first connecting track is determined according to the virtual road indicating identification.
It can be understood that the virtual finger path identifier is mainly generated according to the streamline trajectory, and is adjusted based on the visual effect of the virtual finger path identifier.
Thus, the first wire trace should be substantially the same as the second wire trace, with the difference that: the second connecting track is a streamline planning track of the simulated walking line from the design angle of a movable operation design party; the first connecting line track is a walking line track simulated under the guidance of the virtual road guiding mark from the participation angle of the activity running participant.
Referring to fig. 3 and 4, a 1-d 1 and a 2-d 2 each have corresponding three-dimensional geographic location coordinates; if the streamlines are not required to be determined again, the three-dimensional geographic position coordinates of a 2-d 2 do not change, and the three-dimensional geographic position coordinates of a 2-d 2 in the embodiment of the invention do not change.
a 1-d 1 are changed according to the position adjustment of the virtual road guiding sign, and the following is exemplified with reference to fig. 3 and 4:
the position of the generated virtual road sign a1 is the same as the position of a2, the position of c1 is the same as the position of c2, and the position of d1 is the same as the position of d 2.
Only the position of the virtual road sign b1 is slightly different from the position of b 2. The distance between the position of b1 and the position of b2 can be calculated, and the distance value is smaller than a preset distance threshold value, the position verification of the virtual road indicator b1 is passed.
Fig. 5 is a schematic diagram illustrating a first connecting line track with missing virtual road sign according to an embodiment of the present invention, and as shown in fig. 5, the virtual road sign b1 is omitted in design, so that the first connecting line track is a connecting line connecting a1, c1 and d1, compared with the second connecting line track, the error value is larger, and a position with a larger error value appears between a1 and c1, so that the verification between the positions of a1 and c1 does not pass.
Fig. 6 is a schematic diagram illustrating a first connection track with a wrong position of the virtual road indicator according to the embodiment of the present invention, as shown in fig. 6, because the position of the virtual road indicator b1 is wrong, the first connection track is a connection line connecting a 1-d 1, and compared with the second connection track, the error value is larger, and the position with the larger error value appears at b1, so the position verification of b1 does not pass.
According to the method for verifying the generated virtual road indicating identifier, the first connecting track is compared with the second connecting track, the position of the virtual road indicating identifier is verified according to the comparison result, whether the position of the virtual road indicating identifier is reasonable or not can be verified, and omission in the design process is avoided.
On the basis of the above embodiment, comparing the first connection trajectory with the second connection trajectory, and verifying the position of the virtual guide identifier according to the comparison result includes:
specifically, the device determines a comparison reference position of the first connecting line track and the second connecting line track; further, a first virtual finger path identifier in the first connecting line trajectory and a first streamline inflection point in the second connecting line trajectory may be used as comparison reference positions, referring to fig. 3, the first virtual finger path identifier is a 1; referring to fig. 4, the first streamline inflection point is a 2. a1 and a2 serve as comparison reference positions for comparing the first linking trajectory and the second linking trajectory.
Specifically, the device determines sampling points to be compared respectively on the first connecting line track and the second connecting line track according to a preset distance; the preset distance can be set independently according to actual conditions, and if the scale corresponding to the first connecting line track and the second connecting line track is large, such as an outdoor activity scene, the preset distance can be selected to be a large value; if the scale corresponding to the first connecting line track and the second connecting line track is small, such as an indoor activity scene, the preset distance can be selected to be a small value.
Taking the example of selecting 10 meters at the preset interval, starting from the first virtual road sign of the first connecting line track, determining a sampling point at an interval of 10 meters, and sequentially recording as n1, n 2-nx.
From the first streamline inflection point of the second connecting track, a sampling point is determined at an interval of 10 meters, and the sampling points can be sequentially recorded as m1 and m 2-mx according to the lighting sequence.
The sample points to be compared are n1 and m1, n2 and m2, and so on, up to nx and mx.
Specifically, the device calculates the position deviation value between corresponding sampling points on the first connecting line track and the second connecting line track in sequence from the comparison reference position in pairs; referring to the above example, the position deviation value between n1 and m1, i.e., the distance L11 between the three-dimensional geographic position coordinate corresponding to n1 and the three-dimensional geographic position coordinate corresponding to m1, is calculated.
Specifically, the device verifies the position of the virtual road indication mark according to the comparison result of the position deviation value and a preset deviation threshold value. If L11 is less than the preset deviation threshold, the verification of the position of n1 is passed. And continuously calculating the position deviation value between n2 and m2, namely the distance L22 between the three-dimensional geographic position coordinate corresponding to n2 and the three-dimensional geographic position coordinate corresponding to m 2.
By analogy, when ni is calculated (for example, close to b1), as shown in fig. 3, Lii is smaller than the preset deviation threshold, the location verification of ni passes, and the location deviation value between ni +1 and mi +1 is continuously calculated, which is not described again.
When ni is calculated (e.g., close to b1), Lii is equal to or greater than the preset deviation threshold as shown in fig. 5 or 6, the location verification of ni fails, and the location deviation value between ni +1 and mi +1 is not calculated.
Further, the virtual route guidance mark may be corrected at ni, the position of the corrected virtual route guidance mark and the mi position are determined as comparison reference positions, and the step of determining sampling points to be compared in the first connecting line track and the second connecting line track respectively according to a preset distance is continuously performed.
The method for verifying the generated virtual road guiding identification provided by the embodiment of the invention can further accurately verify whether the position of the virtual road guiding identification is reasonable or not, and avoids omission in the design process.
On the basis of the foregoing embodiment, verifying the location of the virtual road sign according to the comparison result between the location deviation value and a preset deviation threshold includes:
specifically, if the device determines that all the position deviation values are smaller than the preset deviation threshold value, the position verification of all the virtual road indicating identifications is passed; reference may be made to the description of the above embodiments, which are not repeated.
Specifically, if the device determines that at least one position deviation value is greater than or equal to the preset deviation threshold, the position verification of the virtual road indicator does not pass. Reference may be made to the description of the above embodiments, which are not repeated.
The method for verifying the generated virtual road guiding identification provided by the embodiment of the invention can further accurately verify whether the position of the virtual road guiding identification is reasonable or not, and avoids omission in the design process.
On the basis of the above embodiment, the method further includes:
specifically, the device determines the first position deviation value greater than or equal to the preset deviation threshold value and the corresponding position on the first connecting line track as the target position; as shown in fig. 5 or fig. 6, the position of ni is the target position.
Specifically, the device generates a prompt message for correcting the virtual road directing identifier at the target position. The correction reason may include a missing virtual road indication at the target position, or a position error of the virtual road indication, and the embodiment of the present invention does not distinguish between the two.
After the generation of the prompting message, the method steps of the generated virtual road guiding identification can be executed continuously at the target position.
The method for verifying the generated virtual road directing identification provided by the embodiment of the invention can quickly determine the correction position of the virtual road directing identification, thereby improving the design efficiency of the road directing identification.
On the basis of the above embodiment, the determining a comparative reference position of the first connecting track and the second connecting track includes:
specifically, the device takes a first virtual road indicator in the first connecting line track and a first streamline inflection point in the second connecting line track as comparison reference positions. Reference is made to the above description and no further exclusions are made.
The method for verifying the generated virtual road guiding identification provided by the embodiment of the invention can further accurately verify whether the position of the virtual road guiding identification is reasonable or not, and avoids omission in the design process.
On the basis of the above embodiment, generating the position and the indication information of the virtual road guiding identifier; correspondingly, the generating the position and the indication information of the virtual road guiding identifier includes:
specifically, the device tracks the shooting position of a camera in the process of navigating the virtual moving scene according to the streamline at a first person visual angle; as shown in fig. 2, the first-person perspective simulates the height of the user's own perspective, and the preset traveling speed travels along at least a part of the path in the streamline to truly simulate browsing the virtual activity scene in person. The lines on the ground in fig. 2 represent streamlines, and the arrow direction of the lines represents the streamline method.
The visual angle height can be set independently according to actual conditions, and can be selected to be 1.7m, and the preset traveling speed can be set independently according to actual conditions, and can be selected to be 2 m/s.
The streamline can be understood as a pre-designed streamline planning design route, and the streamline is a streamline planning design route which is expressed visually in a virtual activity scene.
A camera may be understood as a camera that shoots a virtual live scene, which may be built into Unity, which records the camera shooting location in real time. And in the process of navigating the virtual movable scene according to the streamline at the first person visual angle, the shooting position of the camera is the same as the visual angle position of the person corresponding to the first person visual angle.
The camera shooting position may be represented by three-dimensional geographic coordinates. That is, as the view angle position of the person moves, the camera shooting position follows the movement.
Specifically, the device takes the camera shooting position as a viewpoint position, and determines the position of the virtual road indication mark according to the camera shooting position, the streamline inflection point and the first person view angle if the streamline inflection point falls into the view range of the first person view angle. The viewpoint position may be understood as the above-described view angle position of the person corresponding to the first-person view angle.
The visual field range can be understood as the range of the fan-shaped area which can be touched by the sight of a person.
Fig. 7 is a schematic diagram of a streamline creation according to an embodiment of the present invention, and as shown in fig. 7, a streamline is created in advance according to three-dimensional position coordinate points, and specifically includes a directional path of the streamline created by sequentially connecting the three-dimensional position coordinate points.
The streamline inflection point may include a first type streamline inflection point, which is a three-dimensional position coordinate point where an angle deviation value is greater than a preset angle threshold. FIG. 8 is a schematic view illustrating inflection points of a first type of streamline according to an embodiment of the present invention; as shown in fig. 8, the three-dimensional position coordinate point C is a first-type streamline inflection point.

The activity participation status may include spectators, media, and athletes, etc. where the streamlines corresponding to the media and the athletes, respectively, may partially overlap in a particular area, such as an event activity mixing area.
Referring to fig. 9, for example, the media corresponding streamlines are in directions a1 to B1 to C1; the player corresponds to a streamline direction from a2 to B2 to C2 with B1 and B2 being the first coincident three-dimensional position coordinate points.
The streamline inflection point may include a third type streamline inflection point, which is a three-dimensional position coordinate point at the divergent path. FIG. 10 is a schematic diagram illustrating a third type of inflection point of a streamline in accordance with an embodiment of the present invention; as shown in fig. 10, three-dimensional position coordinate points C to D constitute one path, and three-dimensional position coordinate points C to E constitute another path, the three-dimensional position coordinate point C being a three-dimensional position coordinate point at a branch path.
According to the camera shooting position, the streamline inflection point and the first person visual angle, the position of the virtual road indication mark is determined, and the method specifically comprises the following steps:

Responding to the action of adjusting the initial position, and simulating and transferring to a viewing angle of a browse adjusting position at the camera shooting position; the user can adjust the position of the guidepost marked with the evacuation channel through the mouse.
The simulation is transferred to the viewing angle of the browsing adjustment position, which can be understood as that the viewing angle is transferred to the direction of the guidepost marked with the 'evacuation channel' so that the sight line is perpendicular to the plane of the virtual guidepost mark, and the viewing angle is kept at the original place of the camera shooting position. The user can easily determine whether the adjustment position is reasonable, such as whether the writing on the fingerboard marked with the "evacuation lane" can be seen clearly, whether the position of the fingerboard is easy to see, and the like.
In response to determining the act of adjusting the location, determining a location of the virtual way heading. The adjustment position can be continuously adjusted according to the viewing angle of the browsing adjustment position, when the adjustment position is determined to reach the expected target, the user executes the action of determining the adjustment position, and the adjustment position at the moment is used as the position of the virtual road guide identification. The expected target can be set autonomously according to the actual objective condition, and referring to the above example, for example, the vertical distance from the virtual fingerpost to the streamline can be calculated, the vertical distance should be smaller than the preset vertical distance threshold, and/or the text content on the virtual fingerpost identifier is identified by using the preset model simulating human eyes, and the accuracy reaches the preset threshold.
The vertical distance can be understood as the vertical distance between the point of the virtual fingering mark perpendicular to the ground and the streamline.
