Qt 安装
PC 端 下载安装即可 https://mirrors.ustc.edu.cn/qtproject/official_releases/qt
树莓派：Qt开发套件和opencv安装
sudo apt-get install qt4-dev-tools libqt4-dev 不用qt core 的话，其实只要按照 qt4-qmake就行了(只做 pro 文件生成makefile文件，我们目的也仅仅如此) sudo apt-get install qt4-qmake
sudo apt-get install libopencv-dev PC上开发好后考到树莓派上，修改pro的链接库和头文件目录

测试程序
#include <iostream>
#include <opencv2/opencv.hpp>
using namespace std;
using namespace cv;
int main(int argc, char **argv)
{
Mat im = imread(argv[1]);
Mat gray;
cvtColor(im, gray, CV_RGB2GRAY);
imwrite ("gray.jpg",gray);
return 0;
}
qmake Rpi.pro
make
多出了gray.jpg这幅图像。
成功
