Embodiment 1
[0065] Embodiment 1: Drawing method of driving training site
[0066] In the drawing method of the driving training site in one embodiment of the present invention, the device connection can refer to figure 1 . figure 1 Among them, differential service refers to providing GNSS carrier phase differential service to RTK equipment. The data storage service refers to the standard electronic drawing service for the driver training program provided to the software of the mobile terminal. In addition, the actual electronic map of the driving training site with real coordinates drawn and collected by the mobile terminal can be stored, which is convenient for use in the driving training system. and, figure 1 In RTK, the RTK device receives the differential service received by the mobile terminal through wireless means such as Bluetooth to perform RTK calculation, and at the same time sends the high-precision positioning coordinate information after calculation to the mobile terminal...
Embodiment 2
[0088] Embodiment 2: Drawing method of driving training site
[0089] Such as Figure 6 As shown, the drawing method of the site to be drawn in this embodiment includes the following steps:
[0090] In step 101: the mobile terminal downloads the site information of the driving training site to be drawn, and the site information includes electronic drawings and data of the driving training site.
[0091] Specifically, in this step, the mobile terminal downloads the electronic drawing data of the driving training project to be drawn from the data storage server. The electronic drawing contains the coordinates of each inflection point of the graphic, and these coordinates are local plane coordinates based on the origin A point.
[0092] Thereafter, in step 102: the first inflection point A is determined in the actual site.
[0093] Thereafter, in step 103: the coordinates of the first inflection point A in the WGS84 coordinate system are determined by the RTK device.
