opencv_contrib编译错误:类没有成员 [英] opencv_contrib compilation error: class has no member

问题描述

我必须实现SURF算法进行图像拼接.我在使用库时遇到问题，如

I have to implement the SURF algorithm for image stitching. I was having trouble with the libraries, as listed here

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括"opencv_contrib"库，但没有用.

After trying the solutions I could find, I removed the opencv and started to build from scratch. I tried to include the 'opencv_contrib' library during installation, but it didn't work.

所以我安装了opencv，然后尝试集成软件包，如int他 github存储库所述.包裹.在
使-j2 行，我不断收到以下错误.

So I installed opencv, and then tried to integrate the package as told int he github repository of the package. During the
make -j2 line, I keep getting the following error.

推荐答案

/home/akshat/opencv_contrib/modules/ximgproc/src/sparse_match_interpolators.cpp:171:52: error: ‘const class cv::_InputArray’ has no member named ‘isVector’

证明这是版本不兼容. ximgproc中的代码期望与cv(特别是cv::_InputArray)不同的接口，而不是库存中提供的接口.

testifies this is a version incompatibility. The code in ximgproc expects a different interface from cv (specifically, cv::_InputArray) than the one your stock one is providing.

您的选择如下:

• 尝试与已安装的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

• try the version of the opencv-contrib codebase that corresponds to your installed version of cv
• make yet another attempt to build the newer cv that corresponds to your current opencv-contrib
