Accurate Reconstruction for Planar Contour Based on Segmentation and Recognition Techniques
Weiyong Wu · Journal of Engineering Graphics · 2007
Accurate reconstruction of planar contour mixed with straight lines and arcs is achieved with position or tangent continuity.Based on segmentation and recognition technology for planar contour,constraint least square(CLS) algorithm is proposed to reconstruct arcs with boundary constraints.CLS is realized under the situation of five types of boundary constraints: single corner point,double corner points,single tangent point,single corner point,single tangent point and double tangent points.To avoid accumulating error caused by reconstruction with boundary constraints,an optimized algorithm is discussed to control the global error.Some examples are presented at last.
