1)视频读取
import cv2 cap = cv2.VideoCapture('E:\\Video\\20000105_224116.dav') #地址 while(True): ret,frame = cap.read() if(ret): # gray = cv2.cvtColor(frame,cv2.COLOR_BGR2GRAY) cv2.imshow('input',frame) else: break if cv2.waitKey(1)==27: break cap.release() cv2.destroyAllWindows()
2)转化图片
# -*- coding: utf-8 -*- """ Created on Mon Nov 5 15:21:15 2018 @author: chenjin10 """ import cv2 vc = cv2.VideoCapture('E:\\Video\\binggan.dav') c=0 rval=vc.isOpened() while rval: c = c + 1 rval, frame = vc.read() if rval: cv2.imwrite('E:\\Video\\binggan\\'+'camera1_binggan'+str(c) + '.jpg', frame) #命名方式 print(c) else: break vc.release()
以上这篇python实现视频读取和转化图片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。
