Abstract: The present disclosure provides a system and a method for analyzing graphical data of an object. The system is implemented on a computing device linked to a database. The system receives a point cloud file corresponding to the object from the database, extracts point cloud data from the point cloud file, and meshes point cloud data to generate coordinate data corresponding to vertices for a plurality of meshed triangles. The system calculates distances between each of the meshed triangles and a fitting plane and a normal vector for each meshed triangle. The system calculates an included angle between the normal vector of each meshed triangle and a normal vector of the fitting plane to determine the accuracy of the point cloud data patches, and generates a report containing an accuracy analysis of the point cloud data for the object and a point cloud statistical analysis report.

Abstract: An electronic device including a processing unit and a storage device receives a point cloud, and converts the point cloud into a mesh model including a first surface and a second surface engaged with the first surface. Then, the processing unit determines a plurality of first boundary points on the first surface, generates a plurality of first projection points for the plurality of first boundary points on the second surface, and generates a first fixed area based on the plurality of first projection points. The processing unit divides the first fixed area into a plurality of first sub-areas and adds a first additional point into each of the plurality of first sub-areas.
