Python 摄像头每隔多长时间拍摄照片 

初学者 有什么写的不对的请见谅，请指正

import time
import cv2
import datetime


def get_pic(camera_idx=0,seconds=5):
    time_start = time.time()
    cap = cv2.VideoCapture(camera_idx)
    ret, frame = cap.read()
    while ret:
        time_start2 = time.time()
        #print(time_start2-time_start)
        if time_start2-time_start >= seconds:
            NowOnTxt = datetime.datetime.strftime(datetime.datetime.now(), '%m.%d-%H.%M.%S')
            ret, frame = cap.read()
            cv2.imwrite(NowOnTxt + ".jpg", frame)
            print("时间差：5秒")
            time_start = time_start2
    cap.release()
# try:
# except KeyboardInterrupt:
#
#     print("Interrupted!")


if __name__ == '__main__':
    try:
        get_pic()

    except KeyboardInterrupt:

        print("Interrupted!")

但是有一个小问题 就是 我没法中断他  也请各位大佬批评指正。
