Python+OpenCV采集本地摄像头的视频
人气:0本文实现了用Python和OpenCV配合,调用本地摄像头采集视频,基本上函数的话看opencv的官方文档就Ok了(The OpenCV Reference Manual Release 2.4.7.0)
上代码:
import cv2 import cv2.cv def getCam(): window_name='show image' cv2.namedWindow(window_name,cv2.WINDOW_NORMAL) video_cap_obj=cv2.VideoCapture(0) if video_cap_obj==None: print('video caoture error') if video_cap_obj.open(0)==False: print('open error') while True: retval,image=video_cap_obj.read() cv2.cv.ShowImage(window_name,cv2.cv.fromarray(image)) if cv2.waitKey(10)==27: break video_cap_obj.release() if __name__=='__main__': getCam()
效果如图:
