安装
从链接选择合适的脚本文件
在命令行下
$ chmod +x opencv.sh
$ ./opencv.sh
运行OpenCV
Python
#!usr/bin/env python
#filename.py
from cv2.cv import *
img = LoadImage("/home/USER/Pictures/python.jpg")
NamedWindow("opencv")
ShowImage("opencv",img)
WaitKey(0)
运行：
$ python filename.py
C
opencvtest.c
#include
#include<opencv2/highgui/highgui.hpp>
int main()
{
IplImage* img = cvLoadImage("/home/USER/Pictures/python.jpg",CV_LOAD_IMAGE_COLOR);
cvNamedWindow("opencvtest",CV_WINDOW_AUTOSIZE);
cvShowImage("opencvtest",img);
cvWaitKey(0);
cvReleaseImage(&img);
return 0;
}
编译运行：
$ gcc -ggdb `pkg-config --cflags opencv` -o `basename opencvtest.c .c` opencvtest.c `pkg-config --libs opencv`
$ ./opencvtest
C++
opencvtest.cpp
#include<opencv2/highgui/highgui.hpp>
using namespace cv;
int main()
{
Mat img = imread("/home/USER/Pictures/python.jpg",CV_LOAD_IMAGE_COLOR);
imshow("opencvtest",img);
waitKey(0);
return 0;
}
编译运行
$ g++ -ggdb `pkg-config --cflags opencv` -o `basename opencvtest.cpp .cpp` opencvtest.cpp `pkg-config --libs opencv`
$ ./opencvtest
简化编译使用opencv的程序
bash 脚本 ~/.compile_opencv.sh
#!/bin/bash
echo "compiling $1"
if [[ $1 == *.c ]]
then
gcc -ggdb `pkg-config --cflags opencv` -o `basename $1 .c` $1 `pkg-config --libs opencv`;
elif [[ $1 == *.cpp ]]
then
g++ -ggdb `pkg-config --cflags opencv` -o `basename $1 .cpp` $1 `pkg-config --libs opencv`;
else
echo "Please compile only .c or .cpp files"
fi
echo "Output file => ${1%.*}"
添加命令别名：
$ alias opencv="~/.compile_opencv.sh"
使用该脚本
$ opencv opencvtest.c
$ ./opencvtest
