树莓派入门教程-树莓派4安装树莓派相机驱动（ubuntu mate 20.04）

说明：

• 本教程主要介绍如何在树莓派4的Ubuntu mate 20.04上安装树莓派驱动
• 默认情况下，树莓派4上安装的Ubuntu mate 20.04是没有带有rpi-clone、rpi-imager 和 raspi-config等工具，需要额外安装
• 测试环境：树莓派4b 2G + Ubuntu MATE 20.04.3 LTS + 树莓派鱼眼摄像头

操作步骤

• 接上摄像头

注意排线的接线方向

• 下载raspi-config的deb包，官方链接

$ wget http://mirrors.ustc.edu.cn/archive.raspberrypi.org/debian/pool/main/r/raspi-config/raspi-config_20201108_all.deb

• 安装相关依赖包

$ sudo apt install lua5.1 libatopology2 libfftw3-single3 libsamplerate0 alsa-utils

• 安装deb包

$ sudo dpkg -i raspi-config_20201108_all.deb

• 挂载

$ df -h

tmpfs          185M  16K  185M  1% /run/user/1000

$ mount /dev/mmcblk0p1 /boot 

• 添加用户到群组

$ sudo usermod -aG video ubuntu

• 打开raspi-config配置

$ sudo raspi-config

• 选择 3 Interfacing Options

• 选择 P1 Camera

• Enable camera interface

• 安装V4l2工具包

$ sudo apt-get install v4l-utils
$ v4l2-ctl --list-devices
bcm2835-codec-decode (platform:bcm2835-codec):
        /dev/video10
        /dev/video11
        /dev/video12
        /dev/media1
bcm2835-isp (platform:bcm2835-isp):
        /dev/video13
        /dev/video14
        /dev/video15
        /dev/video16
        /dev/media0
mmal service 16.1 (platform:bcm2835-v4l2):
        /dev/video0

• 重启树莓派

• 检测是否接上摄像头

$ vcgencmd get_camera
supported=1 detected=1

• 设置完之后测试以下是否能正常使用，输入以下以下命令，正常情况下树莓派系统的桌面上会生成一张摄像头捕捉到的图像

$ raspistill -v -o $HOME/Desktop/test.jpg
