我试图运行的代码片段在下面的OpenCV/C++示例http://docs.opencv.org/3.1.0/d7/dff/tutorial_feature_homography.html#gsc.tab=0C++中的OpenCV findHomography()函数
部分代码下面给出未定义rererence:
std::vector<Point2f> obj;
std::vector<Point2f> scene;
for(size_t i = 0; i < good_matches.size(); i++)
{
//-- Get the keypoints from the good matches
obj.push_back(keypoints_object[ good_matches[i].queryIdx ].pt);
scene.push_back(keypoints_scene[ good_matches[i].trainIdx ].pt);
}
Mat H = findHomography(obj, scene, RANSAC);
我得到以下编译就行错误
/home/yudori/Documents/qt_projects/featureTest/main.cpp:57: error: undefined reference to `cv::findHomography(cv::_InputArray const&, cv::_InputArray const&, int, double, cv::_OutputArray const&, int, double)'
Mat H = findHomography(obj, scene, RANSAC);
我检查了“calib3d.hpp”头文件,它似乎包含findHomography函数的类似声明,但我忍不住想我错过了一些东西。我在Ubuntu上运行opencv 3.1.0,我对C++很陌生,请帮忙。
感谢...我不知道怎么说跳过过去我 :) – yudori
