The Vectorization of Engineering Drawings Based on Statistics

radius and thcn approximately express the lines in broken lines [8]. In this paper we present algorithms by using In this paper we choose the run length code as a statistic/geometric features and simulating human primary expression of line drawings for it may contain vision mechanism to extract lines and arcs for all information and is easy to extract skeletons of lines. vcctoriration of engineering drawings. Experimental We propose a statistic vfctorization method which results for complex lint drawings confilm may eliminate noises. improve the precision and speed performances of these algorithms. of recognition.
