Road crack detection device and detection method
The invention relates to the technical field of road crack detection, in particular to a road crack detection device and a road crack detection method, and aims to solve the problem of data deviation caused by pavement crack detection in a moving process. The road crack detection device comprises a detection body, the detection body is mounted on a test vehicle, and the detection body is in sliding connection with the test vehicle; the sliding direction is parallel to the normal running direction of the test vehicle, a telescopic driving mechanism is installed on the test vehicle, the output end of the telescopic driving mechanism is in transmission connection with the detection body, the telescopic driving mechanism is used for driving the detection body to move in the direction opposite to the running direction of the test vehicle, and a camera device is arranged at the head of the test vehicle. In the running process of the test vehicle, the telescopic driving mechanism keeps the same speed as the running speed of the test vehicle to push the frame body to move backwards, so that the detection body and the crack pavement are in a relatively static state, and stable image data acquisition of the crack pavement by the line laser and the area-array camera is realized.
本发明涉及公路裂缝检测技术领域，针对在移动过程中对路面裂缝进行检测产生数据偏差的问题，具体是涉及一种公路裂缝检测装置及检测方法，包括有检测本体，检测本体安装于测试车上，检测本体与测试车之间为滑动连接，滑动方向平行于测试车常态下的行驶方向，测试车上安装有伸缩驱动机构，伸缩驱动机构的输出端与检测本体传动连接，伸缩驱动机构用于驱动检测本体向相反与测试车的行驶方向移动，测试车的首部设置有摄像装置，本申请中在测试车行驶的过程中通过伸缩驱动机构保持与测试车行进的相同速率推动架体开始向后进行移动，使得检测本体与裂缝路面处于相对静止状态，从而实现线激光器和面阵相机对裂缝路面进行稳定的图像数据采集。
