linux环境用opencv读取图片,opencv在linux系统下利用从cv2进行摄像头读取操作

读取一直错误  根本没显示 ,后来查阅了好久发现是ubuntu中的摄像头褐诶主机的摄像头不匹配的问题,

来到主机,将主机中相机权限打开,进行共享,再回到ubuntu进行cheese命令检验,终于实现视频读入操作!可谓艰辛!

代码如下:

# -*- coding: UTF-8 –*-

import numpy as np

import cv2

# Connect the built-in camera to 'cap'

cap = cv2.VideoCapture(0)   # release

while (True):

ret,color_frame = cap.read()

cv2.imshow('test.avi', color_frame)

if cv2.waitKey(1) == ord('q'):

break

cap.release()

cv2.destroyAllWindows()
