本文详细介绍了在Raspberry Pi上安装OpenCV的过程，包括修改更新源、更新系统、安装基础库及python-opencv，最后验证安装是否成功。文章提供了清华、科大和阿里云的更新源选项。

1.修改更新源
sudo vi /etc/apt/sources.list
科大源：
deb http://mirrors.ustc.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi
deb-src http://mirrors.ustc.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi
清华源：
deb https://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi
deb-src https://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi
阿里云：
deb http://mirrors.aliyun.com/raspbian/raspbian/ stretch main contrib non-free rpi
deb-src http://mirrors.aliyun.com/raspbian/raspbian/ stretch main contrib non-free rpi

sudo vi /etc/apt/sources.list.d/raspi.list
deb http://mirrors.ustc.edu.cn/archive.raspberrypi.org/debian/ stretch main ui

2.更新系统
sudo apt-get update
sudo apt-get upgrade

3.更新基础库
sudo apt-get install libjpeg-dev
sudo apt-get install libatlas-base-dev
sudo apt-get install libtiff5-dev
sudo apt-get install libpng12-dev
sudo apt-get install libqtgui4 libqt4-test
sudo apt-get install libjasper-dev

如果报依赖错误，可以跳过，暂时不影响。

sudo apt-get update
sudo apt-get upgrade

4.安装python-opencv
sudo apt-get install python-opencv

报以下错误就是因为基础库或python-opencv没有安装

libhdf5_serial.so.103: cannot open shared object file: No such file or directory

5.检查opencv是否安装成功
pi@raspberrypi:~ $ python
