ABSTRACT:
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.
