问题描述
所以我正在尝试使用:
sift = cv2.xfeatures2d.SIFT_create()
，并且出现此错误:
cv2.error: OpenCV(3.4.3) C:\projects\opencv-python\opencv_contrib\modules\xfeatures2d\src\sift.cpp:1207: error: (-213: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 in function 'cv::xfeatures2d::SIFT::create'
我正在使用Python 3.5.0和opencv(3.4.3)，而我只是在使用空闲状态.这是在我尝试安装TensorFlow并尝试四处查看并安装了opencv-contrib-python之后发生的，但是我仍然遇到相同的错误.预先谢谢您，如果没有提供足够的信息，我深表歉意.
I am using Python 3.5.0 and opencv(3.4.3) and I am just using idle. This occured after I tried to install TensorFlow and I have tried looking around and have installed opencv-contrib-python but I am still getting the same error. Thank you in advance and I apologise if I have not included enough info
推荐答案
我遇到了同样的问题.似乎SIRF和SURF 在opencv> 3.4.2.16 中不再可用.我选择了较旧的opencv-python和opencv-contrib-python版本，并解决了此问题.这是关于opencv-python的历史版本，我使用以下代码:
I had the same problem. It seems that SIRF and SURF are no longer available in opencv > 3.4.2.16. I chose an older opencv-python and opencv-contrib-python versions and solved this problem. Here is the history version about opencv-python, and I use the following code :
pip install opencv-python==3.4.2.16
pip install opencv-contrib-python==3.4.2.16
修改
对于Anaconda用户，只需此即可，而不是pip
For Anaconda User just this instead of pip
conda install -c menpo opencv
这将安装cv2 3.4.1以及运行SIFT所需的一切
this will install cv2 3.4.1 and everything you need to run SIFT
祝你好运〜
