Linux下安装并使用Java开发opencv的配置

个人安装配置的为opencv3.0版本；

1) 安装gcc以及cmake等软件(不过ubuntu下默认差不多都有了吧…)

sudo apt-get install build-essential python-dev cmake

2) 下载所用的opencv源包并解压缩

3) 新建一个build文件夹

cd ~/opencv
mkdir build
cd build

4) 在终端里输入:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make
sudo make install

我make时花了好久。。。（网太渣！）

 官网上有一个文档, 专门讲怎么用java开发的

http://docs.opencv.org/doc/tutorials/introduction/desktop_java/java_dev_intro.html

1) 首先, 需要安装ant:

sudo apt-get install ant

2) 其次 需要运行cmake, 关键是cmake的参数, 

cmake的参数要这样写:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -DBUILD_TESTS=OFF ..

3) 用上面那样的参数运行cmake以后, 再:

make -j8
sudo make install

这样就可以成功make了…

以上操作结束后, 看看build文件夹, bin目录下是不是有一个

opencv-248.jar

文件:



如果有的话 就说明成功安装了opencv的java组件…
