It should be noted that the straight curved table and the peg-by-peg coordinate table may be input into the road image acquisition apparatus by a photographer before taking a road image. The electronic map usually already contains a plurality of existing known routes, and when the routes represented by the input straight curved tables and the pile-by-pile coordinate tables are known routes, the routes marked in the map information are overlapped with the known routes in the electronic map; when the route represented by the input straight curved table and the pile-by-pile coordinate table is an unknown route, the following steps are performed: when a road needs to be newly opened up, the route needing to be shot is an unknown route, and the route marked in the map information is not overlapped with the known route in the electronic map.
Optionally, the control chip may be further configured to receive an input road name; and is specifically configured to generate a target road image according to the road name, the location information, the original road image, and time information corresponding to the original road image.

In one embodiment, after the photographer inputs the straight curved table and the pile-by-pile coordinates to the road image acquisition device in advance, the control chip may determine to obtain the pile number information corresponding to the current position according to the coordinate information and the pile number information of the route. In another embodiment, in the shooting process, the shooting person may also input the stake mark information corresponding to the current position, and the application is not limited herein. For example, at the starting point, the stake number information may be input as "stake number: k6+000 ".
The control chip can also calculate the speed information corresponding to the current position according to the position information and the time information. For example, the distance L from the current position to the position at which measurement is started can be known from the position information, the time T from the current time to the time at which measurement is started can be known from the time information, and the average speed of measurement can be calculated from the distance L and the time T, that is, the speed information. Alternatively, the distance m that the coordinates move within the previous time t may be known from the position information, and the speed information may be obtained from the m and the calculation, where the shorter the time t, the higher the real-time performance of the speed information. The specific calculation mode of the speed information is not limited in the present application.
