摘　　要：结合物理科研及教学实践,提出了一种基于图像处理的获取曲线上点的实际坐标的方法,实际应用表明,该方法简单实用,能精确复原待绘制的物理曲线.In physics research and physics education,we often want to draw multiple physical curves in the same coordination system. In this paper,we offered a method to get the coordinates from the image of physical curve by image processing. With only four coordinates value,we can get coordinates of all dots on the curve and draw the corresponding curve accurately.
