很简单，生成一个窗口实时显示摄像头的内容，然后将摄像头对准这个窗口。代码如下：
import cv2
clicked = False
def onMouse(event, x, y, flags, param):
global clicked
if event == cv2.EVENT_LBUTTONUP:
clicked = True
cameraCapture = cv2.VideoCapture(0)
cv2.namedWindow(‘Window‘)
cv2.setMouseCallback(‘Window‘, onMouse)
success, frame = cameraCapture.read()
while success and cv2.waitKey(1) == -1 and not clicked:
cv2.imshow(‘Window‘, frame)
success, frame = cameraCapture.read()
cv2.imwrite(‘recursive.png‘, frame)
cv2.destroyAllWindows()
cameraCapture.release()
效果图如下：
