树莓派5一键安装C++版本OpenCV

安装环境

本人当前的安装环境：

1. 树莓派5
2. Raspberry Pi os (64-bit) Debian12 Bookworm
   镜像下载地址
   
3. 我这里是将镜像安装好后直接安装opencv，如果不是刚安装好的镜像需要注意是否有openCV的python之类的安装过，不然可能出现编译错误

一、扩展内存

确保树莓派有足够空间

sudo raspi-config

1. 打开配置界面
   
2. 配置高级设置
   
3. 确保所有SD卡可用
   
4. 根据提示重启树莓派即可

二、建立安装脚本

#创建安装脚本
touch Opencv-4-8-0.sh
#给权限
sudo chmod 777 Opencv-4-8-0.sh 

脚本名最好保持一致，或者是不能被opencv*识别到 因为脚本中有sudo rm -rf opencv*可能会删除掉脚本
填充脚本内容
脚本获取链接由此入 | 直接复制我下面的内容，都是一模一样的

#!/bin/bash
set -e
install_opencv () {
echo ""

case `cat /etc/debian_version` in
10*) echo "Detecting Debian 10, Buster. "
	;;
11*) echo "Detecting Debian 11, Bullseye. "
	;;
12*) echo "Detecting Debian 12, Bookworm. "
	;;
esac

echo ""
echo "Installing OpenCV 4.8.0"
echo "It will take minimal 2 hour !"

}

cd ~

if [ -d ~/opencv/build ]; then
  echo " "
  echo "You have a directory ~/opencv/build on your disk."
  echo "Continuing the installation will replace this folder."
  echo " "
  
  printf "Do you wish to continue (Y/n)?"
  read answer

  if [ "$answer" != "${answer#[Nn]}" ] ;then

三、一键安装

脚本会自行执行 安装依赖/编译/安装 过程-耐心等待即可

如果出现下述问题 由此入访问此链接

运行脚本 整个过程约

./Opencv-4-8-0.sh 

这个地方会卡好一会👇

后面就是安装了----->安装完成👇 可喜可贺
