我希望在 opencv 的 opencv-contrib 中使用附加算法。我正在尝试使用 contrib 中的非免费算法构建 opencv。
我是使用 cmake 的新手。
我能够在 cmake build 中完成配置/生成阶段，以构建 opencv（附加配置）。当我使用 Visual Studio 构建时，没有生成 cv2.pyd。
我确实看到了一个 cv2.cp37-win_amd64.pyd 文件。当我 pip 安装从 camke 构建生成的 .ee 文件时，它已经在 site-packages 文件夹中可用。
以下是生成步骤的输出：

我确实看到创建了一个 .egg 文件。但是，当我使用 .egg 文件安装时，其他算法 SIFT/SURF 不可用。
我也确实在示例文件夹中看到了 python 示例，但没有 cv2.pyd 文件。
我想知道是否有人可以指导我，让 opencv 使用其他算法。
