Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0026] Such as figure 1 As shown, the overall registration method of the high-precision multi-source ground laser point cloud described in the present invention comprises the following steps:
[0027] Step 1: collect original feature constraints, input control points, and use the input control points as the first ground laser site;
[0028] Step 2, in all the ground laser sites adjacent to the first ground laser site, select the feature constraint with the same name corresponding to the original feature constraint;
[0029] Step 3: Preset the first ground laser site as the registration base station, and calculate whether the number of feature constraints with the same name in all adjacent ground laser sites can be registered with the first ground laser site, if all can be ac...
