簡介
OpenCV是一個基于BSD許可（開源）發(fā)行的跨平臺計算機視覺庫，可以運行在Linux、Windows、Android和Mac OS操作系統(tǒng)上。它輕量級而且高效——由一系列C函數(shù)和少量C++類構(gòu)成，同時提供了Python、Ruby、MATLAB等語言的接口，實現(xiàn)了圖像處理和計算機視覺方面的很多通用算法。
編譯和測試方式
1.配置編譯環(huán)境
1)安裝wget工具。
yum install wget -y
2)安裝OpenCV依賴庫和工具
yum install -y git gcc-c++ -y
3)安裝cmake依賴
yum install -y git gcc-c++ cmake
----結(jié)束
2.獲取源碼
獲取“OpenCV-3.0.0”源碼包。
cd /usr/local/src
wget https://github.com/opencv/opencv/archive/3.0.0.tar.gz
3.編譯和安裝
編譯“OpenCV-3.0.0”并進行安裝。
cd /usr/local/src/
tar -zxvf 3.0.0.tar.gz
cd opencv-3.0.0/
mkdir build
cd build/
cmake ..
make -j8 && make instal
4.運行和驗證
查看安裝OpenCV所生成的庫文件和頭文件。
ll /usr/local/lib
回顯內(nèi)容如下，表示安裝正常。
