ABSTRACT:
An automated mechanism for measuring the amount of accuracy loss attributable to reverse engineering processes that use 3D scan data is discussed. The embodiments provide a mechanism that displays to a user the effect scan data editing and CAD remodeling operations have on scan data accuracy. Additionally, the user can choose the way the graphical display illustrates the error distribution on the model such as by color mapping and whisker mapping. The accuracy loss may be displayed to the user after finishing an editing/modeling command or during the previewing of the command thereby allowing a user to take appropriate action. Parameters may also be adjusted programmatically based on the amount of accuracy loss determined to be attributable to scan data editing or CAD remodeling operations.
