解决: AttributeError: module 'cv2' has no attribute 'SURF'

AttributeError: module 'cv2' has no attribute 'SURF'

遇到该问题时,网友多是建议补个包,即pip install opencv-contrib-python
我在补完之后又出现下面这样的错误:
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(专利保护) and is excluded in this configuration; Set OPENCV_ENABLE_NONFREE CMake option and rebuild the library in function ‘cv::xfeatures2d::SIFT::create’
将opencv版本退到3.4.2即可解决,卸载之前的包(pip uninstall opencv-python),然后

pip install opencv-python==3.4.2.16
pip install opencv-contrib-python==3.4.2.16

注意以上两条命令==左右没有空格

又报错误:

  'module' object has no attribute 'xfeatures2d'

变更后为

Detector= cv2.xfeatures2d.SURF_create()
