使用 contrib 模块安装 openCV [英] Installing openCV with contrib modules

问题描述

我使用 opencv3.3.1 运行 python3.6(32 位).

I was running python3.6 (32 bit) with opencv3.3.1.

我看到了这个教程，所以我正在尝试与 SIFT 描述符进行蛮力匹配:http://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_feature2d/py_matcher/py_matcher.html

I saw this tutorial so I was trying out the brute force matching with SIFT descriptors: http://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_feature2d/py_matcher/py_matcher.html

我读到包括 SIFT 在内的一些模块不再包含在默认安装中，需要单独安装.我在 python 官方网站上找到了带有 contrib 模块的 opencv3 下载(我假设它包含 SIFT).具体来说，我从这里下载了 opencv_contrib_python-3.3.0.10-cp36-cp36m-win32.whl (md5):https://pypi.python.org/pypi/opencv-contrib-python#downloads

I read that some modules including SIFT were no longer included in the default installation and needed to be installed separately. I found on the official python website a download for opencv3 with the contrib modules (which I assumed contains SIFT). Specifically I downloaded opencv_contrib_python-3.3.0.10-cp36-cp36m-win32.whl (md5) from here: https://pypi.python.org/pypi/opencv-contrib-python#downloads

我已经卸载了我以前的 opencv 并安装并导入了这个新版本的 opencv 并验证我正在运行新版本.

I have uninstalled my previous opencv and installed and imported this new version of opencv and verified that I am running the new version.

然而，当我尝试使用 cv2.SIFT() 时，我仍然收到模块 cv2.cv2 没有属性SIFT"的错误.

However, still when I try to use cv2.SIFT() I am still getting the error that module cv2.cv2 has no attribute 'SIFT'.

我是否下载了正确的软件包?包括 SIFT 在内的所有 opencv 模块都应该包含在我安装的包中吗?

Did I download the correct package? Are all opencv modules including SIFT supposed to be included in the package I installed?

推荐答案

要启用 opencv-contrib 模块，您必须从源代码重建 opencv 库.在 CMake 配置中，您必须启用它，指定变量 OPENCV_EXTRA_MODULES_PATH 和 opencv_contrib 模块所在的路径，例如 ...wherever_you_downloaded_it/opencv_contrib/opencv_contrib-master/modules.

For enabling opencv-contrib modules, you have to rebuild your opencv lib from source. In CMake config, you have to enable it, specifying variable OPENCV_EXTRA_MODULES_PATH with path where you have opencv_contrib modules such as ...wherever_you_downloaded_it/opencv_contrib/opencv_contrib-master/modules.

然后，使用 make 构建 opencv 将构建模块，而 make install 将使用其他 opencv 库安装这些库.

Then, building opencv with make will build modules, and make install will install these libs with other opencv libs.
