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()
以上这篇python实现将视频按帧读取到自定义目录就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持python博客。
