摘要
在汽车覆盖件冲压工艺设计过程中 ,采用投影点集表示曲面的局部形状 ;采用改进的旋转图像方法对汽车覆盖件曲面的局部形状作出大略而快速的识别 ;提出了高度图像法 ,对局部曲面形状作出精确的识别。
The local shape of a vehicle cover panel surface is very important in the course of its stamping designing process. To fastly recognize surface local shape, an improved method based on spin images is represented. Then, to recognize local shape more accurately, template-matching method is proposed. On the basis of the method, ideal results are obtained.
