OpenCV安装
OpenCV安装
声明:此文是在天下文章一大抄的百度帮助下,完成的;首先说明,本人并非原创,根据大神文章尝试实验,我只想记录一下,安装的过程和问题以及解决方法!如侵犯您的权益请告知
环境:
1. 系统: ContOS7
2. GCC: gcc version 4.8.5 (GCC) 及以上均可
3. cmake: cmake version 2.8.12.2 及以上均可
4. Python: Python 2.7.11
安装基本工具:
在安装之前,要先配置好epel源,因为下面的某些安装在系统自带的源中找不到
yum -y install epel-release
首先是gcc,g++等这些基本的工具
yum install gcc gcc-c++ yum install cmake yum install python-devel numpy
yum install python-imaging
安装numpy如果出错的朋友,可以通过源码包安装(其它的我是没出现问题)
# 我安装的是1.9.0版本,经检测时可用的(如有版本问题自行下载) wget http://jaist.dl.sourceforge.net/project/numpy/NumPy/1.9.0/numpy-1.9.0.zip unzip numpy-1.9.0.zip cd numpy-1.9.0 python setup.py install
安装OpenCV依赖:
yum install gtk2-devel yum install libdc1394-devel yum install libv4l-devel yum install gstreamer-plugins-base-devel yum install gtk* # ==========虽说我也不太清楚这些依赖包都是干啥的吧!我反正是装上了=============== yum install gtk+-devel gimp-devel gimp-devel-tools gimp-help-browser zlib-devel libtiff-devel libjpeg-devel libpng-devel gstreamer-devel libavc1394-devel libraw1394-devel libdc1394-devel jasper-devel jasper-utils swig libtool nasm # 友情提示:如果出错,可以一个一个装,然后解决依赖,我这里是没有出问题
yasm
wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz tar zxvf yasm-1.3.0.tar.gz cd yasm-1.3.0 ./configure --prefix=/usr make && make install
安装ffmpeg(大坑,我之前已经装好了一套opencv,但是就是因为装ffmpeg的问题,运行的时候各种错误,导致没办法使用),以下为正确姿势
yum install libopencore-amr-devel.x86_64 libopencore-amr.x86_64 yum install libmp3lame.x86_64 libmp3lame-devel.x86_64 yum install libass.x86_64 libass-devel.x86_64 yum install opus.x86_64 opus-devel.x86_64 yum install pulseaudio-libs.x86_64 pulseaudio-libs-devel.x86_64 yum install libsoxr-devel.x86_64 libsoxr.x86_64 yum install speex.x86_64 speex-devel.x86_64 yum install libvorbis-devel.x86_64 libvorbis.x86_64 yum install libvpx.x86_64 libvpx-devel.x86_64 yum install libxvidcore-devel.x86_64 libxvidcore.x86_64 # 以上安装包,建议全部安装上,否则按编译的ffmpeg的时候可能会出现各种缺失
图1安装ffmpeg所需的安装包
下面就开始一个个的安装了!!!(要有耐心,有句mmp不知当讲不当讲)
1、lame
url:https://sourceforge.net/projects/lame/files/lame/3.100/lame-3.100.tar.gz/download tar -zxvf lame-3.100.tar.gz cd lame-3.100 ./configure --enable-shared --prefix=/usr make make install

4、xvid
重点提示:安装版本必须要在1.3.0之上(安装低版本会遇到坑,可自行尝试)
url:http://downloads.xvid.org/downloads/xvidcore-1.3.3.tar.gz tar zvxf xvidcore-1.3.3.tar.gz cd xvidcore-1.3.3/build/generic ./configure --prefix=/usr make make install
5、x264

6、libdts
tar -zxvf libdts-0.0.2.tar.gz cd libdts-0.0.2 ./configure --prefix=/usr make make install
7、a52
url:http://liba52.sourceforge.net/files/a52dec-0.7.4.tar.gz tar -zxvf a52dec-0.7.4.tar.gz cd a52dec-0.7.4 ./configure --prefix=/usr make make install
8、faad2

这12个安装完成后,就可以尝试安装ffmpeg了
url:http://ffmpeg.org/releases/ffmpeg-3.4.1.tar.bz2 tar -jxvf ffmpeg-3.4.1.tar.bz2 cd ffmpeg-3.4.1 ./configure --prefix=/usr --enable-gpl --enable-shared --enable-libmp3lame --enable-libogg --enable-libvorbis --enable-libamr-nb --enable-libamr-wb --enable-libxvid --enable-libx264 --enable-liba52 --enable-liba52bin --enable-libfaac --enable-libfaad --enable-libfaadbin --enable-pp --enable-pthreads --disable-ffserver --disable-ffplay make # 编译时间有点长,过程中可能会出现错误,可以根据错误,定位一下(之前咱们的一些依赖都已经安装了,应该不会出现太多错误了,如有错误,请自行Google) make install
如果make时,出现一下错误,可根据错误进行安装
错误:ERROR: x265 not found using pkg-config
# 去掉编译参数: --enable-libx265
错误: ERROR: libx264 not found
ftp://ftp.videolan.org/pub/x264/snapshots/last_x264.tar.bz2 tar -jxvf last_x264.tar.bz2 cd last_x264 ./configure --enable-static make && make install
安装OpenCV
1. 从官网下载 opencv-2.4.13.zip
2. 执行安装
unzip opencv-2.4.13.zip cd opencv-2.4.13 # 此处大约1分钟,会看到很多打印信息,包括ffmepg的配置信息 cmake CMakeLists.txt # 编译时间很长(大约30分钟) make make install
安装过程时间可能会有点长10~30分钟左右,编译完成之后OpenCV就安装到了指定的/usr/local下面的一些目录中,库文件就安装到了/usr/local/lib下,Python的模块安装位置是:/usr/local/lib/python2.7/site-packages,执行 ls /usr/local/lib/python2.7/site-packages/ 可以看到两个文件,一个是cv2.so一个是cv.py
3. 复制到python环境中
ln /usr/local/lib/python2.7/site-packages/cv.* /home/zk/python_env/scrapy_env/lib/python2.7/site-packages
4. 验证
#!/usr/local/bin/python # -*- coding: utf8 -*- import cv2 import os, sys BASE_PATH = os.path.dirname(os.path.abspath(__file__)) file_path = os.path.join(BASE_PATH, "fj.jpg") img = cv2.imread(file_path) cv2.namedWindow("Image") cv2.imshow("Image", img) cv2.waitKey(0) cv2.destroyAllWindows()
终于成功了,浪费整整一天时间!!!好吧,我承认,我比较笨!
