Problems solved by technology

[0010] (2) In the process of highway quality detection, non-differential data processing is carried out for all detection areas, which is poorly targeted and takes a long time to process data;

[0011] (3) The defect target recognition process data search area in the highway quality process is relatively large, the defect target recognition algorithm is more complex, and the data processing performance requirements of the detection device are relatively high;

[0012] (4) The data acquisition process is separated from the data processing process in the road quality process, and the detection personnel cannot obtain the detection results in real time during the detection process
