import cv2
cap = cv2.VideoCapture(0)  # 打开摄像头
while (1):
    # get a frame
    ret,frame = cap.read()
    frame = cv2.flip(frame,1)  #  将图像左右调换回来正常显示
    # show a frame
    cv2.imshow("capture",frame)  # 生成摄像头窗口
    if cv2.waitKey(1) & 0xFF == ord('q'):  # 如果按下q 就截图保存并退出
        cv2.imwrite("test.png",frame)  # 保存路径
        break
