AttributeError: module 'cv2' has no attribute 'xfeatures2d'
时间: 2023-11-06 16:09:02 浏览: 41
AttributeError: module 'cv2' has no attribute 'xfeatures2d'是由于使用的是新版本的OpenCV导致的错误。在新版本中,cv2模块已经没有xfeatures2d属性了。解决这个问题的方法有两种:
解决办法1:回退到OpenCV的旧版本。可以通过在PyCharm的终端中执行以下命令来卸载当前安装的OpenCV版本并安装旧版本:
pip uninstall opencv-python
pip install opencv-python3.4.2
pip install opencv-contrib-python3.4.2
解决办法2:如果你使用的是OpenCV的新版本(如4.5.3版本),可以使用cv2.SIFT_create()函数代替cv2.xfeatures2d.SIFT_create()函数。新版本的函数可以实现与旧版本函数相同的功能。

AttributeError: module cv2 has no attribute xfeatures2d
这个错误通常是因为缺少opencv-contrib-python模块的原因。请尝试通过以下命令安装opencv-contrib-python:
```
pip install opencv-contrib-python
```
如果已经安装了opencv-contrib-python,可以尝试更新版本:
```
pip install --upgrade opencv-contrib-python
```
如果还是无法解决问题,可以考虑重新安装OpenCV。
AttributeError: module 'cv2' has no attribute 'xfeatures2d
The error message "AttributeError: module 'cv2' has no attribute 'xfeatures2d'" occurs when you try to access the xfeatures2d module in the cv2 library, but it is not available.
This error usually occurs when you are using an older version of OpenCV that does not have the xfeatures2d module. The xfeatures2d module was introduced in OpenCV 3.0, so if you are using an older version, you will need to upgrade to a newer version to use this module.
To upgrade OpenCV, you can use pip or conda. For example, to upgrade to the latest version using pip, you can run the following command:
```
pip install opencv-python
```
If you are using conda, you can run the following command:
```
conda install -c conda-forge opencv
```
Once you have upgraded to a newer version of OpenCV, you should be able to access the xfeatures2d module without encountering the AttributeError.
