1.2、OpenCV-Python的安装和测试

安装OpenCV-Python首先要安装Python环境，也可以直接安装anaconda环境。我这里还是使用单独的Python环境

1、下载Python安装包

https://www.python.org/downloads/

我使用的是windows环境，所以下载对应的安装包，双击安装即可。

C:\Users\xxx>python
Python 3.11.4 (tags/v3.11.4:d2340ef, Jun  7 2023, 05:45:37) [MSC v.1934 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

2、安装OpenCV-Python

pip install opencv-python

3、测试

在命令行中输入：import cv2，没有报错就说明安装成功了.

C:\Users\xxx>python
Python 3.11.4 (tags/v3.11.4:d2340ef, Jun  7 2023, 05:45:37) [MSC v.1934 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>>

至此，OpenCV-Python就安装完成.
