c++ - opencv_contrib 编译错误 : class has no member

Question

我必须实现用于图像拼接的 SURF 算法。我在使用库时遇到了问题，如所列 here

在尝试了我能找到的解决方案后，我删除了 opencv 并开始从头开始构建。我试图在安装过程中包含“opencv_contrib”库，但没有成功。

所以我安装了opencv，然后按照int he github repository的指示尝试集成包包的。在
制作-j2行，我不断收到以下错误。

证明这是版本不兼容。 ximgproc 中的代码需要来自 cv 的接口(interface)(特别是 cv::_InputArray)，而不是您的现有接口(interface)提供的接口(interface)。

您的选择是:

• 尝试与您安装的 cv 版本相对应的 opencv-contrib 代码库版本
• 再次尝试构建与您当前的 opencv-contrib 相对应的更新的 cv
