Method for repairing slight damage of asphalt road
The invention relates to the field of asphalt road damage repair, and in particular relates to a method for repairing slight damage of an asphalt road. The method comprises the steps of S1 completing calibration of a single camera in a standard calibration plant, establishing a relation between image pixels of the single camera and a standard scene position point, and then performing binocular calibration to determine structural parameters of dual cameras, so that the dual cameras have the capability of identifying spatial point position parameters on the road surface; S2 carrying out real-time exploration on the road surface damage part by using dual cameras near the road surface damage part, and carrying out three-dimensional reconstruction on the road surface damage part according to image information obtained by the cameras; S3 according to guidance of coordinates obtained through three-dimensional reconstruction, moving a repairing mechanism to the position above the road surface damage part, and controlling the repairing mechanism to conduct road surface repairing; and S4 repeating the above processes until the road surface slightly-damaged pit is completely repaired. The method is used for timely repairing the slight damage of the highway pavement, can timely stop the damage before the slight damage enlarges, and is simple to operate and high in practicability.
本发明涉及沥青公路破损修复领域，尤其涉及一种修复沥青公路微破损的方法，包括S1：在标准标定厂房内完成单个摄像头的标定，建立单个摄像头图像像素和标准场景位置点之间的联系，随后进行双目标定，以确定双摄像头的结构参数，从而使得双摄像头具有识别路面上空间点位置参数的能力；S2:在路面破损处附近，利用双摄像头路面破损处进行实时勘探，根据摄像头获得的图像信息，对路面破损进行三维重建；S3:根据三维重建所得坐标的指引，将修复机构移动至路面破损处上方，并控制修复机构做路面修复动作；S4：重复以上过程，直至路面微破损坑洞被完全修复。本发明用于公路路面微破损的及时修复，能在微破损扩大之前及时止损，操作简单、实用性强。
