使用Python从视频中提取一帧帧图片

import cv2
import os

def videoToImage(sourceVideoPath, outputImagePath):
    times = 0   # 初始化times
    frameFrequency = 20 # 提取视频的频率，每25帧提取一个
    id = 0    # 迭代控制保存的图片文件名,从355开始计数
    camera = cv2.VideoCapture(sourceVideoPath)# 读取时视频文件流
    while True:
        times += 1
        res, image = camera.read()
        if not res:
            print('not res , not image')
            break
        # 判断间隔多少帧
        if times % frameFrequency == 0:
            id += 1
            cv2.imwrite(os.path.join(outputImagePath, str(id)) + '.jpg', image)
    print('图片提取结束')
    camera.release()


if __name__ == '__main__':
    # 要提取视频的文件名
    sourceVideoPath = r'E:\1\1\1.mp4'
    # 输出图片到指定目录文件夹下
    outputImagePath = r'E:\1\1'

    videoToImage(sourceVideoPath, outputImagePath)
