1.下载opencv代码 git clone GitHub - opencv/opencv: Open Source Computer Vision Library 2.下载opencv-contrib代码 git clone github.com/opencv/openc 3.链接opencv-contrib到opencv cd your-opencv-dir/opencv ln -s your-opencv-contrib-dir/opencv-contrib your-opencv-dir/opencv/opencv-contrib 4.配置,编...
错误提示“error: ‘xfeatures2d’ has not been declared”通常是因为OpenCV的contrib模块没有正确安装或配置。 在OpenCV中,xfeatures2d模块包含了一些非免费的算法,如SIFT和SURF,这些算法由于专利问题,在OpenCV的主模块中默认不包含。要使用这些算法,需要安装OpenCV的contrib模块。 解决步骤: 安装OpenCV的contrib模块: ...
解决opencv_contrib4.1.2批生成后缺失xfeatures2d.lib的方法如下：确保源文件完整：从GitHub上重新下载OpenCV的官方源文件和对应的opencv_contrib源文件，确保下载的是完整且未损坏的版本。安装必要的工具和依赖：安装最新版本的CMAKE工具，它是配置和生成OpenCV项目所必需的。安装支持C++开发的IDE，如Visual ...
下载opencv_contrib源码:https://github.com/Itseez/opencv_contrib下载opencv源码:https://sourceforge.net/projects/opencvlibrary下载安装cmake:sudo apt install cmake 要重新编译一下opencv ,因为在这个额外的库中有需要opencv中的依赖 2.查看当前库需要哪些依赖 ...
错误描述:运行cv::xfeatures2d::SURF::create 崩溃,出现Error: The function/feature is not implemented (This algorithm is patented and is excluded in this configuration; Set OPENCV_ENABLE_NONFREE CMake option and rebuild the library) 解决:依据提示 cmake 时,OPENCV_ENABLE_NONFREE 勾上。
从GitHub下载opencv_contrib源码和opencv源码。opencv_contrib包含了xfeatures2d等额外模块。安装编译工具：使用sudo apt install cmake安装cmake，以便重新编译OpenCV。配置CMake：查看CMakeLists.txt文件，理解如何使用cmake定义模块。确保在CMake配置中启用了xfeatures2d模块。这通常需要在CMake命令中添加D...
