object-dimension-measurement:使用OpenCV和numpy检测对象的尺寸

对象尺寸测量 使用opencv和numpy实时估算对象的尺寸：-应用轮廓法首先找到最大轮廓 - Convert img to grey scale - then apply guassian blur on image - Apply Canny edge detector algorithm to find the edges (input the blurred image) - Apply erosion & dialation on image - Find the contours - Optimize getContours() to detect the A4 sheet paper - Warp: to get sequence of contours - Apply padding to remove the corner extra pixels - Find obje
