树莓派+qt+opencv

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[]);
     Mat gray;
     cvtColor(im, gray, CV_RGB2GRAY);
     imwrite ("gray.jpg",gray);
     ;
 }

结果截图

qmake Rpi.pro

make

多出了gray.jpg这幅图像。

成功
