The invention discloses a long-distance detection method for tiny deformation of an expressway pavement. The method comprises the following steps: step 1, installing an identification device on an inspection vehicle, wherein the identification device comprises a camera and a line laser light source; the line laser light source irradiates the road surface and forms bright latticed lines through diffuse reflection, and the bright latticed lines are completely and clearly shot and captured by the camera; step 2, measuring the straightness of each transverse and longitudinal grid line in the grid lines in the step 1; 3, judging whether the transverse and longitudinal grid lines obtained in the step 2 have distortion or not; 4, if the distortion exists, recording the distorted grid lines, and positioning the distortion position; and 5, calculating the position where the pavement deformation occurs, and carrying out real-time early warning on passing vehicles and a pavement maintenance department. The long-distance detection method for the tiny deformation of the highway pavement provided by the invention is simple in detection principle, low in cost and relatively high in recognition capability, and can recognize the tiny deformation of the pavement at a relatively long distance.
本发明公开了一种针对高速公路路面微小形变的远距离检测方法包括以下步骤：第一步、在巡检车上安装识别装置，识别装置包括摄像头和线激光光源；线激光光源照射路面通过漫反射形成的明亮网格状线条，被摄像头完整清晰地拍摄捕捉；第二步、对第一步中网格状线条中的每一条横纵网格线条的直线度进行测量；第三步、判断第二步中所获得的横纵网格线是否存在畸变；第四步、若存在畸变，记录发生畸变的网格线，定位畸变发生的位置；第五步、计算路面形变发生的位置，并对过往车辆和路面养护部门进行实时预警。本发明所提供的一种针对高速公路路面微小形变的远距离检测方法检测原理简单，成本低且具有较高识别能力、能够在较远距离识别路面微小形变。
