Abstract:
1. A computer-based method for measuring errors of a plurality of workpieces manufactured according to a three-dimensional model, the method being performed by execution of non-transitory computer readable program code by at least one processor of at least one computer system, the method comprising: (a) receiving the three-dimensional model and a point cloud of each workpiece from a storage system; (b) constructing triangles using the point cloud to convert each point cloud to a measured triangular mesh model; (c) aligning each measured triangular mesh model to the three-dimensional mode comprising: (d) comparing each measured triangular mesh model with the three-dimensional model to check for differences between the two models, so as to obtain errors of each workpiece; (e) generating one or more analysis reports according to the errors of each workpiece; and (f) outputting the one or more analysis reports to a display screen.
