最近需要用Qt写一个界面，然后就需要配置Qt和OpenCV。我的电脑现状是之前有安装过OpenCV，所以只需要安装Qt和配置OpenCV环境；linux系统，Ubuntu 4.4.0-21,37 x86-64.

1.安装Qt，首先下载Qt，我的安装版本在这里：（软件太大了，上传不了。若要用，官网无法下载可以给我留言），直接在终端运行，在安装的过程中需要注册Qt账号，这个可以通过网页去注册；

2.新建一个工程，在“.pro”文件中配置OpenCV的库文件，配置清单如下：

INCLUDEPATH += /usr/local/include\
/usr/local/include/opencv\
/usr/local/include/opencv2


LIBS += /usr/local/lib/libopencv_calib3d.so\ 
/usr/local/lib/libopencv_core.so\
/usr/local/lib/libopencv_features2d.so\
/usr/local/lib/libopencv_flann.so\
/usr/local/lib/libopencv_highgui.so\ 
/usr/local/lib/libopencv_imgcodecs.so\ 
/usr/local/lib/libopencv_imgproc.so\ 
/usr/local/lib/libopencv_ml.so\ 
/usr/local/lib/libopencv_objdetect.so\
/usr/local/lib/libopencv_photo.so\
/usr/local/lib/libopencv_shape.so\
/usr/local/lib/libopencv_stitching.so\
/usr/local/lib/libopencv_superres.so\
/usr/local/lib/libopencv_videoio.so\
/usr/local/lib/libopencv_video.so\
/usr/local/lib/libopencv_videostab.so
