Ubuntu 14.04.3 安装 opencv 3.0.0

来源：互联网发布：mac os最新版本下载编辑：程序博客网时间：2024/06/10 02:41

刚才要做对视频每一帧的提取，按照网上的一种方法安装了Opencv 3.2，然而一切安装完毕后执行以下代码：

import cv2catcher = cv2.VideoCapture('3.avi')

报错，提示：

Unable to stop the stream: Inappropriate ioctl for device

各种调整都没能解决问题，无奈重新安装了3.0.0版本的Opencv，总结步骤如下。

已有环境：CUDA 8.0 cudnn 7.5 Python 2.7 scipy numpy theano 等深度学习套件

参考：http://rodrigoberriel.com/2014/10/installing-opencv-3-0-0-on-ubuntu-14-04/

（一）安装依赖项

sudo apt-get -y install libopencv-dev build-essential cmake git libgtk2.0-dev pkg-config python-dev python-numpy libdc1394-22 libdc1394-22-dev libjpeg-dev libpng12-dev libtiff4-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev libtbb-dev libqt4-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils unzip

（二）下载Opencv源码

http://opencv.org/releases.html

下载后解压到Home文件夹，在解压出来的文件夹中新建一个名为build的文件夹，并在build内打开终端。

（三）编译，安装

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_LAPACK=OFF ..make -j $(nproc)sudo make install

在执行 make -j $(nproc) 时，编译到92%报错：

modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/build.make:290: recipe for target 'modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/src/graphcuts.cpp.o' failedmake[2]: *** [modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/src/graphcuts.cpp.o] Error 1

经过谷歌找到了解决方法，原来官方的3.0.0版本发布时尚不支持CUDA 8.0，现在已经修复：

参考https://github.com/opencv/opencv/pull/6510/commits/10896129b39655e19e4e7c529153cb5c2191a1db

即进入到~/opencv-3.0.0/modules/cudalegacy/src文件夹中，打开graphcuts.cpp文件，删除第45行的预处理语句，改为

#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER) || (CUDART_VERSION >= 8000)

重新编译即可。

卸载：

make uninstall

cd ..

sudo rm -r build

sudo rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv /usr/include/opencv2 /usr/local/share/opencv /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv* /usr/local/lib/libopencv*
