摘要
从线性分割工程图入手,提出了一种线性化的轮廓匹配方法.首先通过线性分割工程图的过程将相交的图素从交点处分离出来,消除工程图中的相交情况,获得独立的图素。
Beginning with linear separation of an engineering drawing, a linearized method of contour matching is presented. The mathematical characteristics of all kinds of intersection are found first. With these characteristics, the engineering drawing is analyzed and the intersections are to be found. The intersecting pixels are separated from the intersections so as to eliminate any intersection in the drawing and isolated pixels are obtained. The isolated pixels are then recognized with the linearized method without having to detect or track the contour pixels. The linearized method includes the acquisition of the contour pixel with the scanning segment inheritance method and the matching of the contour with the trapezium centerline method.
