Claim 5:
6. The method for correcting the abnormal Point Cloud Data of claim 1, wherein in the steps that the Image Processing Unit follows the Primitive Voxel Space Data to divide the Primitive Point Cloud Data and obtain a plurality of Sub-Point Cloud Set and the corresponded plural Distribution Feature Data, the steps include:
the Image Processing Unit following the plural Voxel Grids of the Primitive Voxel Space Data to divide the Primitive Point Cloud Data into the Sub-Point Cloud Sets;
the Image Processing Unit performing a nearest neighbor index operation, a principal component analysis operation and a de-constraint conversion operation according to the Primitive Point Cloud Setting and obtaining the Distribution Feature Data, which respectively correspond to all neighboring points of each image point in the Sub-Point Cloud Sets;
the Image Processing Unit categorizing the Sub-Point Cloud Sets according to the Distribution Feature Data to obtain a plurality of category labels; and
the Image Processing Unit labels the Sub-Point Cloud Sets according to the category labels.
