System and method for analyzing geometric deviations of a physical object

A system for analyzing geometric deviations of a physical object, the system comprising an application server and a plurality of application terminals, the application server comprising:

• a receiving module configured for receiving point cloud data of a point cloud from a measuring machine which scans the physical object, and for receiving one or more parameters set by a user from one of the application terminals, the one or more parameters comprising a predetermined acceptable tolerance;
• a computing module configured for fitting a least squares model based on the point cloud data according to a least squares method, analyzing the geometric deviations of the physical object by computing a deviating value of each point based on the point cloud data and by comparing the deviating value with the predetermined acceptable tolerance, and obtaining an analysis result;
• a simulating module configured for performing a point cloud simulation by using Open Graphics Library based on the least squares model, the point cloud data, and the analysis result;
• and
• a saving module configured for saving the point cloud simulation, the deviating value of each point and the analysis result.
