Abstract: Road inspection vehicle is a special road detection vehicle, the combination of unmanned driving technology and road detection technology, can solve the problem of unmanned road detection on the future intelligent high-speed. In the process of data collection of road characteristics, it is necessary to rely on road section positioning, line laser scanning pavement, image acquisition and other technical means, and unmanned vehicles in the process of autonomous driving, need to rely on their own radar, camera, GPS positioning device to complete the autonomous obstacle avoidance trail, there are many similarities in the on-board equipment, the unmanned rapid comprehensive road detection vehicle designed in this paper, through the integration of the latest unmanned driving technology and advanced road detection technology, to achieve rapid unmanned operation, Relying on GPS positioning to collect road information more accurately, completing the three-dimensional reconstruction of the road surface and analyzing the status of road diseases is the application of unmanned driving technology in the field of road detection, which brings innovation to the traditional road inspection technology.
