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-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

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
