Question

我必须实现用于图像拼接的SURF算法。我在库中遇到了问题，如here

所列

在尝试了我能找到的解决方案之后，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，但它没有用。

所以我安装了opencv，然后尝试将软件包整合到软件包的github repository中。在期间 make -j2 我一直收到以下错误。

证明这是版本不兼容。 ximgproc中的代码需要与cv（特别是cv::_InputArray）不同的界面，而不是您的库存提供的界面。

您的选择是：

尝试与opencv-contrib

cv

再次尝试构建与您当前的cv对应的较新opencv-contrib

opencv_contrib编译错误：类没有成员
