opencv_contrib编译错误:类没有成员

opencv_contrib compilation error: class has no member

本文关键字：成员 错误 contrib 编译 opencv      更新时间：2023-10-16

我必须实现用于图像拼接的SURF算法。我在图书馆遇到了麻烦，如所列

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

所以我安装了opencv，然后尝试按照包的github存储库中的说明集成包。在
make-j2行，我不断得到以下错误。

证明这是版本不兼容。ximgproc中的代码期望与cv（具体地说，cv::_InputArray）的接口不同于您现有的接口。

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
  • 再次尝试构建与当前opencv-contrib相对应的较新cv
