System and method for detecting defects of objects based on a CAD platform

摘要

A system and method for detecting defects of objects based on a CAD (Computer-Aided Design) platform includes a measurement apparatus ( 10 ), an application server ( 12 ), and a database server ( 14 ). The application server includes a data acquiring module ( 120 ) for acquiring point cloud data of an object and acquiring a three-dimensional digital model of the object; a point cloud cutting ( 121 ) module for cleaning and editing the point cloud data; a point cloud filtering module ( 122 ) for filtering the point cloud data; a data aligning module ( 123 ) for aligning the point cloud data with the three-dimensional digital model of the object; a data comparing module ( 124 ) for comparing the point cloud data with the three-dimensional digital model of the object; and a report management module ( 125 ) for generating a color comparison report. A related method is also disclosed.
