The algorithm presented in this paper firstly obtains the data matrix of the clear outline of planar complex patterns through vectorization and data conversion of the planar complex pattern image or graphic, secondly finds the in- tersection points of scan lines and contours using scan analysis method, and matches the intersection points and calcu- lates midpoints, finally builds the 3D model of the planar complex patterns by the 3D model data matrix that is created using quadratic Bezier curves and post-optimization processing of the model data. This modeling approach can conceive and build a...
