Pump Hydraulic Model Digitization CAD System-Study on Recognition and Digitization of Curve in Engineering Drawings
Li Xin · Mechanical Science and Technology · 2000
In this paper,a pump hydraulic model digitization CAD system is presented. The problems of digitization of curves in engineering drawings are also discussed. We present an tracing algorithm for recognizing curves in image and a algorithm for extracting key points. these algorithms are simple,practical and can give satisfactory solution.
