使用Qmake在树莓派上开发Opencv程序

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-toolssudo 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

TEMPLATE = app
CONFIG += console
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += main.cpp

INCLUDEPATH += /usr/include INCLUDEPATH += /usr/include/opencv

# debug

LIBS += -L/usr/lib     -lopencv_calib3d     -lopencv_contrib     -lopencv_core     -lopencv_features2d     -lopencv_flann     -lopencv_gpu     -lopencv_highgui     -lopencv_imgproc     -lopencv_legacy     -lopencv_ml     -lopencv_objdetect     -lopencv_video

include(deployment.pri)
qtcAddDeployment()

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
