向opencv python添加额外的模块? [英] add extra modules to opencv python?

问题描述

我在 python opencv 中有问题！

I have a problem in python opencv!

我想使用 SIFT 算法，它不是 opencv 包中的默认算法.所以我必须使用额外的模块构建 OpenCV，如下所示:

I want to use SIFT algorithm which is not a default algorithm in opencv package. So I have to build OpenCV with extra modules as bellow:

您可以构建 OpenCV，因此它将包含此存储库中的模块.这是为您准备的 CMake 命令:

You can build OpenCV, so it will include the modules from this repository. Here is the CMake command for you:

$ cd <opencv_build_directory>
$ cmake -DOPENCV_EXTRA_MODULES_PATH=<opencv_contrib>/modules <opencv_source_directory>
$ make -j5
$ make install

<小时>

我完成了所有这些步骤，并成功构建了它.但是当我调用 opencv 的子模块(例如 xfeatures2d、objdetect)时出现错误.我尝试使用以下代码；

---

I did all these steps and it was successfully build. But I'm getting error when I call sub modules of opencv (e.g. xfeatures2d, objdetect). I tried using following code;

$ import cv2
$ x = cv2.xfeatures2d()

它给我的错误是 module' 对象没有属性 'xfeatures2d'".

你有什么想法吗?

推荐答案

1. 从此处
下载 opencv_contrib
2. 从这里
下载opencv
3. 现在创建一个名为 opencv_build
的新目录
4. 现在进入opencv_build目录
5. 这里指向步骤1下载的文件夹
6. 并且 指向步骤 2 中下载的文件夹
7. 在您的 cmake 命令中替换它们的路径.

1. Download opencv_contrib from here
2. Download opencv from here
3. Now create a new directory called opencv_build
4. Now go to opencv_build directory
5. Here <opencv_contrib> points to downloaded folder from step 1
6. And <opencv_source_directory> points to downloaded folder from step 2
7. Substitute their paths in your cmake command.
