Question

新手求教，怎样能将opencv配置到qt里

Answer 1

在你的pro文件里

OPENCV_PATH = C:/opencv/build # 你的opencv folder

INCLUDEPATH += $${OPENCV_PATH}/include \

$${OPENCV_PATH}/include/opencv \

$${OPENCV_PATH}/include/opencv2

CONFIG(release, debug|release) {

LIBS += $${OPENCV_PATH}/x64/vc11/lib/opencv_highgui249.lib \

$${OPENCV_PATH}/x64/vc11/lib/opencv_imgproc249.lib \

$${OPENCV_PATH}/x64/vc11/lib/opencv_core249.lib
# .... 你想用的库 release 版本 /x64, /vc11 对应你的编译器版本
}

CONFIG(debug, debug|release) {

LIBS += $${OPENCV_PATH}/x64/vc11/lib/opencv_highgui249d.lib \

$${OPENCV_PATH}/x64/vc11/lib/opencv_imgproc249d.lib \

$${OPENCV_PATH}/x64/vc11/lib/opencv_core249d.lib
# .... 你想用的库 debug 版本， /x64, /vc11 同上
}

Answer 2

只要在pro文件里面加上
INCLUDEPATH += /usr/local/include \
/usr/local/include/opencv2

LIBS += /usr/local/lib/libopencv_highgui.so \
/usr/local/lib/libopencv_core.so
以上是ubuntu下面的，win下面的也差不多就是找到路径就可以。
如果是控制台程序，在main.c里面加上头文件：

#include <QCoreApplication>
#include <highgui/highgui.hpp>//包含opencv库头文件
#include <cv.hpp>
#include <video/video.hpp>
这种形式，要用到哪些头文件加哪些。
