Road Roughness Detector
The invention discloses a road roughness detector, comprising: a distance measurement module, arranged at the concentric place of the left wheel and/or right wheel at the rear of the vehicle, and is used to detect the current driving distance of the vehicle; An elevation measurement module, set at the wheel track belt of the left and/or right wheels in front of the vehicle. The elevation measurement module includes: a line laser, used to shoot the laser line perpendicular to the road surface; A three-dimensional camera, used to capture the scattered laser line and extract the laser line to obtain the elevation data of the road cross section; The detection module, used to obtain the road roughness detection result according to the elevation data of road cross section. The detector can accurately measure the road roughness detection results through the combination of a line laser and a three-dimensional camera, and is suitable for measurement at various speeds to meet the needs ofurban road roughness detection, thereby effectively improving the accuracy of road roughness detection, applicability and reliability. The detector is simple and easy to operate. 100 - - - - - - - 200 300 10 Ditne210 220 Distanmce Detection measurement Line Dmodule module laser camera Road roughness detector Figure 1 Figure 2
