我正在尝试使用 SIFT/SURF 编译一个 C++ 程序，当我包含时，我收到了这个错误消息:

我正在尝试使用 ROS 和 catkin，在我尝试实现 SIFT/SURF 之前，一切正常。我也试过用普通的 g++ 编译，但没有成功。我尝试了三次安装OpenCV，使用不同的方法，但仍然是相同的结果。
我正在使用 Ubuntu 14.04 和 OpenCV 2.4.10
最佳答案
我遇到了完全相同的问题，SIFT/SURF 现在已移至 github 上的 opencv_contrib 模块 https://github.com/Itseez/opencv_contrib
您必须从 cmake 过程中包含的模块开始构建 opencv，他们有一个教程向您展示如何执行此操作
这些特征现在有命名空间 cv::xfeatures2d 来反射(reflect)贡献的变化
希望对你有帮助
