Claim 0:
1. A method for correcting abnormal Point Cloud Data, applied for a Correction System including an Image Processing Unit and an Optical Scanning Unit, the Optical Scanning Unit scanning an outer structure to create a Primitive Point Cloud Data and transmit the Primitive Point Cloud Data to a Data Base, the method for correcting the abnormal Point Cloud Data comprising the steps of:
the Image Processing Unit reading the Primitive Point Cloud Data from the Data Base; the Primitive Point Cloud Data includes a plurality of Normal Point Data and at least an Error Point Data and a Primitive Voxel Space Data;
the Image Processing Unit following the Primitive Voxel Space Data to divide the Primitive Point Cloud Data and obtain a plurality of Sub-Point Cloud Sets and the corresponded plural Distribution Feature Data; these Sub-Point Cloud Sets have the Normal Point Data and the Error Point Data;
the Image Processing Unit following the Distribution Feature Data to identify the Sub-point Cloud Sets and obtain the Error Point Data; and
the Image Processing Unit following a Distribution Feature Data corresponding to the Error Point Data to make regression operation and correct the Error Point Data into a Normal Point Data.
