使用OpenCV Python提取所有边界框

你去那里：

import cv2im = cv2.imread('c:/data/ph.jpg')gray=cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)contours, hierarchy = cv2.findContours(gray,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)[-2:]idx =0 for cnt in contours:    idx += 1    x,y,w,h = cv2.boundingRect(cnt)    roi=im[y:y+h,x:x+w]    cv2.imwrite(str(idx) + '.jpg', roi)    #cv2.rectangle(im,(x,y),(x+w,y+h),(200,0,0),2)cv2.imshow('img',im)cv2.waitKey(0)
