最近玩OpenCV用到一个双目摄像头，需要调整分辨率为1280×480，研究了一下官方API，找到了设置方法，记录一下，以防忘记

import cv2 cap = cv2.VideoCapture(0) cap.set(cv2.cv.CV_CAP_PROP_FRAME_WIDTH,1280) cap.set(cv2.cv.CV_CAP_PROP_FRAME_HEIGHT,480) while(True): # Capture frame-by-frame ret, frame = cap.read() # Our operations on the frame come here #gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) # Display the resulting frame cv2.imshow("frame" ,frame) if cv2.waitKey(1) & 0xFF == ord('q'): break # When everything done, release the capture cap.release() cv2.destroyAllWindows() 主要就是用了VideoCapture的set方法，里面有各种各样的参数，详见：
