python实现将视频按帧读取到自定义目录
如题,首先读取视频路径,其次根据视频名称创建对应的文件夹,再逐帧将视频帧读入。
import cv2 import argparse import sys import os parser = argparse.ArgumentParser(description='tranfer the vedio to img.') parser.add_argument('-m', '--mode', choices=['folder', 'url'], default='folder') parser.add_argument('-p', '--path', help='Specify a path [e.g. testModel]', default='E:\DATA\pose_h3.6m\S5\Videos') parser.add_argument('-pimg', '--imgpath', help='Specify a path [e.g. testModel]', default='F:\pythonprogram\multi_task\img\S5') args = parser.parse_args(sys.argv[1:]) if args.mode == 'folder': #get video withPath = lambda f: '{}/{}'.format(args.path,f) video = dict((f,cv2.imread(withPath(f))) for f in os.listdir(args.path) if os.path.isfile(withPath(f))) for key,val in video.items(): fram_video = '{}/{}'.format(args.path,key) act_cam=key[:-4] vc=cv2.VideoCapture('{}\{}'.format(args.path,key)) c = 1 # camera # print('{}\{}\{}.jpg'.format(args.imgpath, act_cam,str(c))) path = '{}\{}'.format(args.imgpath, act_cam) isExists = os.path.exists(path) if not isExists: os.makedirs(path) if vc.isOpened(): rval, frame = vc.read() else: rval = False while rval: rval, frame = vc.read() cv2.imwrite('{}\\{}\\{}.jpg'.format(args.imgpath, act_cam,str(c)),frame) # cv2.imwrite('C:\\Users\\65183\\Desktop\\test\\fuck\\'+str(c)+'.jpg', frame) c = c + 1 cv2.waitKey(1) vc.release()
