Example one
As shown in fig. 1 and fig. 2, the present embodiment provides a driving test vehicle information comprehensive display method, including the following steps:
s1: loading map information data which are measured in advance, and importing corresponding driving test vehicle data on the map information data; in practice, the imported vehicle data may be a schematic point, that is, a middle point of the vehicle, or may be imported into a vehicle model.
More preferably in this embodiment, the map information data includes area point coordinate combination, display color, and area information; the regional information is driving test project information; the driving test vehicle information comprises a license plate code, vehicle contour points and a vehicle model. That is, in the present embodiment, the imported vehicle model is adopted as a more preferable embodiment, and as shown in fig. 3, the vehicle model includes an overall model diagram thereof and individual vehicle contour points. The specific implementation mode is as follows: and importing a vehicle model and vehicle model data, wherein the vehicle model data is obtained by measuring actual coordinate points of the vehicle outline. The four key points for determining the vehicle direction angle are two end points of the front wheel axis and the rear wheel axis, and the vehicle model is obtained by rotating the four key points to the zero point direction through coordinate translation to be 0 degree. Alternatively, the vehicle 24 may be directly received in real time without using the data of the model, or the number of contour points may be displayed on the map without limiting the number. In the embodiment, the contents of a region point coordinate set, display colors, region information and the like are all used as the map bottom layer of the vehicle; it is not modified throughout the display process. In the embodiment, the map track drawing and displaying is divided into a map layer, a track layer, a measurement marking layer and a vehicle model display layer.
S2: receiving position data transmitted by driving test vehicles in the driving test process; in practice, all vehicle data in the test room may be received.
Step S21 is also included in this embodiment: and traversing all the vehicle contour points and judging whether all the vehicle contour points are in the corresponding areas, if not, sending corresponding prompt results.

In the process, the nearest distances between all vehicles and the area are displayed, and the measurement information is displayed on the measurement layer. The specific measurement method comprises the following steps: and (4) emitting rays outwards from the front wheel axis and the rear wheel axis of the automobile, and calculating the distance from the intersection point of the side lines of all the regions to the end point. The information is measured to know the real-time intersection relationship between the vehicle and the project area, and a specific schematic diagram is shown in fig. 4.
More preferably, step S2 is specifically: receiving position data transmitted by a driving test vehicle at preset time intervals;
and forming the track data of the vehicle according to the received position data, and displaying the track data at the map information data. The step is mainly used for acquiring the driving track of the driving test vehicle, so that data in the driving test process can be conveniently called subsequently, and the data information is rechecked. The driving process can be monitored in real time in the examination process, so that monitoring personnel can know the whole examination process in detail.
S3: and updating the position of the driving test vehicle at the map information data in real time according to the position data, and further displaying the position at the display module. The distance of the intersection point to the driving test vehicle is displayed at the display module. The specific display effect is shown in fig. 5.

In this embodiment, the method further includes step S4: receiving a trigger operation of a user, tracking the driving test vehicle according to the trigger operation so that the corresponding driving test vehicle is always positioned in the middle of a screen, wherein the trigger operation is a double-click vehicle operation. Specifically, when the map double-click vehicle enters a vehicle tracking mode, the vehicle is always displayed in the middle of a screen, necessary information of the vehicle is displayed at the same time, and if the mode needs to be cancelled, the vehicle can be returned by double-click.
The software device capable of dynamically monitoring all vehicle states in real time is designed through existing geographic information data and vehicle information data when the existing examination room is deployed, the vehicle operation states of the whole examination room can be integrally and globally reflected, the positions of the vehicles can be rapidly and visually obtained at any time, the positions are visually very visually distinct, and the efficiency of examination room operation management experience is greatly improved.
According to the method, a plurality of layers are drawn on the basis of existing geographic information data (mapped high-precision map data) and vehicle information data, wherein the plurality of layers comprise a map layer, a track layer, a measurement marking layer and a vehicle model display layer; and detecting points, lines and surface areas in the map layer by using a computer graphics technology, and further forming a display picture of a vehicle and a site map for monitoring by monitoring personnel.
The invention can integrally and globally reflect the vehicle operation state of the whole field, and can quickly and intuitively obtain the position of the vehicle at any time. The system is beneficial to uniformly managing the vehicles in the examination site, detecting the examination state in real time and rapidly and accurately processing the occurrence of burst time. Based on the technical implementation of the embodiment, for the constructed examination hall, if the display needs to be realized, the examination hall can be realized only by increasing the extremely low cost of a PC (personal computer); the scheme of this embodiment promotes the operation efficiency and the emergency treatment ability of whole examination room through very low cost, possesses higher economic value and social value.
