python目标检测将视频按照帧率切除成图片

python目标检测将视频按照帧率切除成图片，并且允许放入多个多个视频

完整代码如下：

import os
import cv2class VideoSplit:"""将视频分帧为图片source_path: 视频文件存储地址result_path： 图片结果文件保存地址frame: 帧率，每frame帧保存一张图片"""def __init__(self, source_path, result_path, frame=10):self.source_path = source_pathif not os.path.exists(self.source_path):raise Exception("源文件路径不存在！")self.result_path = result_pathself.frame = frameif not os.path.exists(self.result_path):os.makedirs(self.result_path)print("创建文件夹{},".format(self.result_path))def split_video(self):video_list = os.listdir(self.source_path)for i, name in enumerate(video_list):video_list[i] = os.path.join(self.source_path, name)basename = name.split('.')[0]video_result_path = os.path.join(self.result_path, basename)if not os.path.exists(video_result_path):os.makedirs(video_result_path)print("创建子文件夹{},".format(basename))cap = cv2.VideoCapture(video_list[i])print("视频{}开始分帧...".format(name))sum = 0i = 0while True:ret, frame = cap.read()if not ret:breaksum += 1# 保存图片if sum == self.frame:sum = 0i += 1imgname = basename + '_' + str(i) + '.jpg'imgPath = os.path.join(video_result_path, imgname)cv2.imwrite(imgPath, frame)print(imgname)print("{}视频文件提取完成".format(basename))print("完成")if __name__ == "__main__":source_path = r'C:\Users\video'result_path = r'C:\Users\result'tst = VideoSplit(source_path, result_path)tst.split_video()

注意：尽量手动创建两个文件夹video、result
