在OpenCV Python中找不到SIFT或xfeatures2d [英] Unable to find SIFT or xfeatures2d in OpenCV Python

问题描述

最近我使用OpenCV 3.4.1切换回python进行面部检测和模式识别，但是在运行OpenCV进行点识别时，出现错误

I recently switch back to python for facial detection and pattern recognition using OpenCV 3.4.1 However when running OpenCV for point recongnition, I get the error

AttributeError: module 'cv2.cv2' has no attribute 'SIFT_create'

我已经读到将行从sift = cv2.SIFT_create()更改为sift = sift = cv2.xfeatures2d.SIFT_create()应该可以解决此问题.

I have read that changing the line from sift = cv2.SIFT_create() to sift = sift = cv2.xfeatures2d.SIFT_create() should solve this.

但是我得到一个错误

AttributeError: module 'cv2.cv2' has no attribute 'xfeatures2d'.

xfeatures2d是否应包含在OpenCV中?关于如何解决此问题的任何建议?谢谢！

Shouldnt xfeatures2d be included in OpenCV? Any suggestion on how to fix this? Thanks!

推荐答案

我猜您已使用pip安装了opencv-python.该软件包不包括贡献模块.要解决此问题，请卸载opencv-python并安装opencv-contrib-python.

I guess you installed opencv-python with pip. That package does not include contributed modules. To fix, uninstall opencv-python and install opencv-contrib-python instead.
