摘要
探讨了一个新机械图纸识别方法。着重叙述了团、剖面等的识别。采用了一个适合于识别圆的新数据结构。
In this paper, a new recognition algorithm for mechanical drawings is discussed.The algorithm includes two procedures:vectorization and understanding The recognition of cir-des and croas-sections am introduced specially. We developed a new data structure suitingfor the recognition of circles. Expert knowledge is used for the recognition of arrows,cir-des and styles of lines. The processing results of drawing recognition can be used as input data of many CAD/CAM systems. The experiments repasented that our algorithm is highspeed and effective.
