Breakpoint division and section reconstruction method based on depth-first algorithm and PCL

The invention provides a breakpoint division and section reconstruction method based on a depth-first algorithm and a PCL. The breakpoint division and section reconstruction method based on the depth-first algorithm and the PCL comprises the following steps: step 1, carrying out breakpoint data extraction; step 2, automatically dividing breakpoint data on time slices; step 3, carrying out breakpoint data space combination to obtain three-dimensional breakpoint bodies of different faults; 4, storing the three-dimensional breakpoint bodies of different faults in the step 3 into a point cloud data file; 5, fitting a rough plane of the section; 6, cutting the section fitting rough plane; and 7, obtaining an accurate section fitting result. According to the breakpoint division and section reconstruction method based on the depth-first algorithm and the PCL, the efficiency is remarkably improved, the time and the manpower are saved, the number of divided faults and the fault identification precision are more accura
