Python实现视频逐帧提取并保存为图片的完整代码示例

import cv2
import os
def save_img():
  video_path = r'F:\test\video1/'
  videos = os.listdir(video_path)
  for video_name in videos:
    file_name = video_name.split('.')[0]
    folder_name = video_path + file_name
    os.makedirs(folder_name,exist_ok=True)
    vc = cv2.VideoCapture(video_path+video_name) #读入视频文件
    c=0
    rval=vc.isOpened()

    while rval:  #循环读取视频帧
      c = c + 1
      rval, frame = vc.read()
      pic_path = folder_name+'/'
      if rval:
        cv2.imwrite(pic_path + file_name + '_' + str(c) + '.jpg', frame) #存储为图像,保存名为 文件夹名_数字（第几个文件）.jpg
        cv2.waitKey(1)
      else:
        break
    vc.release()
    print('save_success')
    print(folder_name)
save_img()
