step S1, setting a coordinate point and a distance value between the coordinate point and a road base surface to be built, detecting the actual distance between the coordinate point and the road base surface to be built by adopting a distance meter, controlling the distance meter to move forward on the road base surface to be built at a set constant speed value, and acquiring the actual distance value between each part of the road base surface to be built and the set coordinate point; the set distance value is the distance between the actual height of the distance measuring equipment and a preset height value of the road surface, wherein the preset height value of the road surface is the height of the roadbed set in the construction project, and after all the working procedures are processed, the actual height of the roadbed is the same as the set height of the roadbed;

step S2, comparing and calculating a set distance value and an actual distance value between the coordinate point and a road base surface to be constructed, marking a position where the actual distance value is greater than the set distance value as a position to be filled, marking a position where the actual distance value is less than the set distance value as a position to be milled, and respectively calculating actual distance difference values between the position to be filled and the position to be milled and the set distance value; because the distance measuring equipment travels at a constant speed, the actual position coordinates of the position to be filled or milled can be calculated according to the speed multiplied by the time, and then the corresponding equipment stops moving and processes the position when moving to the position, or the moving speed is reduced so that the corresponding equipment fully processes the position to be processed;

step S3, milling the place to be milled, collecting road base surface waste materials generated after milling, crushing the collected road base surface waste materials, and storing the crushed road base surface waste materials for later use; the loss of materials is reduced;

In step S3, the height at which the milling process is performed on the to-be-milled place is the same as the actual distance difference between the to-be-milled place and the set distance value, and in step S4, the image data of the to-be-filled place is monitored in real time by using the image acquisition device.
