人机交互获取图像轮廓点位坐标的研究

摘要

产品设计过程中会遇到以图像形式给出的轮廓,在数控加工时也必须给出廓线的一系列坐标值.在此提出一种采用人机交互的方式,用若干段贝塞尔曲线逼近图像给出的廓线,实现从图像到CAD/CAM系统可以直接利用的坐标数据生成的方法.%Considering the fact that in the product design,the product contour can be presented in the form of images and NC machining asks for profile' s coordinate values,the HMI was proposed to have Bessel curves approximated to the profile given by the images,and to have the coordinate data generation method used in the realization from the image to CAD/CAM system.
