opencv结合python打开摄像头

如果有没理解的地方，点个关注，私信我就行哈~~，看到了会及时回复

废话不多说，代码如下

import cv2 as cv
import numpy as np
from numpy.lib.type_check import imag


def video_demo():
    # VideoCapture()中参数是0,表示打开笔记本的内置摄像头，参数是视频文件路径则打开视频，如capture  = cv.VideoCapture(“../testVideo.avi”)
    capture = cv.VideoCapture(0)
    while True:
        ret, frame = capture.read()
        # 这里做了个镜面水平反转，如果想要上下颠倒，就填 -1
        frame = cv.flip(frame, 1)
        cv.imshow("video", frame)
        c = cv.waitKey(50)
        # c得到的是键盘输入的ASCII码，esc键对应的ASCII码是27
        if c == 27:
            break


def get_image_info(image):
    print(type(image))
    print(image.shape)
    print(image.size)
    print(image.dtype)
    pixel_data = np.array(image)
    print(pixel_data)


# src = cv.imread('C:\\Users\\a1625\\Desktop\\1620697720.jpg')
# cv.namedWindow("myImage", cv.WINDOW_AUTOSIZE)
# cv.imshow("myImage", src)
video_demo()
# cv.waitKey(0)
# cv.destroyAllWindows()
