Abstract

The invention provides a pavement imaging device and method. The pavement imaging device provided by the invention comprises an optical module, a control module and a signal processing module. The control module is connected with the optical module and the signal processing module, and is used for controlling the optical module and the signal processing module. The optical module is connected with the signal processing module. The optical module is used for reflecting an incident light to a pavement along the horizontal direction of the pavement through the rotation of a movable double-sided reflector under the control of the control module, and receiving a light reflected by the pavement. The signal processing module is used for processing the reflected light received by the optical module to acquire a pavement image. According to the invention, the cost is reduced, and the pavement imaging accuracy is improved.

Description

technical field [0001] The invention relates to road surface detection technology, in particular to a road surface imaging device and method. Background technique [0002] The structural depth of the pavement is detected by the pavement imaging technology, and the structural depth characterizes the level of unevenness of the pavement. The structural depth mainly affects the skid resistance of the pavement, and is one of the main technical indicators for evaluating the quality of the pavement. [0003] In the prior art, multiple single-point scanners are used for road surface imaging: above a certain distance from the road surface, multiple single-point scanners are arranged at a certain interval along the horizontal direction of the road surface, and the multiple single-point scanners The road surface can be imaged by scanning in the horizontal direction of the road surface. By moving multiple single-point scanners along the length of the road, images of the road at differ...
