[0064] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0065] see figure 1 , a method for loose identification and calculation of asphalt pavement based on three-dimensional laser technology, comprising the following steps:
[0066] 1. Road laser point cloud data acquisition
[0067] Three-dimensional laser equipment is used to scan the asphalt pavement with loose diseases, and the three-dimensional laser point cloud data of the pavement of the detected road section are obtained. Before the detection starts, it is necessary to select a reference road surface on the road section to be detected to calibrate the 3D laser equipment. The reference road surface has high smoothness, no damage such as chipping, looseness, rutting, etc., and no debris such as gravel and sand. .
[0068] 2. Road laser point cloud data processing
[0069] The local weighted regression scatter smoothing method is used to smooth the laser point cl...
