# 本脚本仅在 Linux环境下 ，测试系统为 Ubuntu22.04 , VPN: 漂亮国(在wsl2中测试后发现不需要)
以下是安装脚本：

```shell
cd ~ && mkdir Shell_person
cd Shell_person && vi install_opencv.sh
```

粘贴以下脚本：

```shell
#!/bin/bash

USER=$(whoami)  # 自动获取当前用户名
LIB_PATH="/home/$USER/Lib"
BUILD_PATH="$LIB_PATH/OpenCV_build"
INSTALL_PATH="$LIB_PATH/OpenCV_install"

# 设定 OpenCV 包名
OPENCV_PKG='opencv-4.8.0'

# 更新和升级包
sudo apt-get update && sudo apt-get upgrade -y

# 安装必需的依赖
sudo apt install build-essential cmake git pkg-config libgtk-3-dev \
     libavcodec-dev libavformat-dev libswscale-dev libv4l-dev \
     libxvidcore-dev libx264-dev libjpeg-dev libpng-dev libtiff-dev \
     gfortran openexr libatlas-base-dev python3-dev python3-numpy \
     libtbb2 libtbb-dev libdc1394-25 -y

# 检查 LIB_PATH 是否存在，如果不存在则创建
if [ ! -d "$LIB_PATH" ]; then
    echo "目录 $LIB_PATH 不存在，正在创建..."
    mkdir -p $LIB_PATH

cd $LIB_PATH
# 克隆仓库前先检查是否已存在
if [ -d "$BUILD_PATH" ]; then
    echo "目录 $BUILD_PATH 已存在，清理中..."
    sudo rm -rf $BUILD_PATH
fi
git clone https://gitee.com/LuIrara/OpenCV_build.git

cd $BUILD_PATH

# 循环遍历当前目录下的所有.zip文件并解压
for z in *.zip; do
    unzip "$z"
done

rm -rf *.zip

# 确保正确的目录结构
if [ ! -d "$BUILD_PATH/$OPENCV_PKG" ]; then
    echo "未找到 $BUILD_PATH/$OPENCV_PKG 目录"
    exit 1
fi

mkdir -p $BUILD_PATH/$OPENCV_PKG/build
cd $BUILD_PATH/$OPENCV_PKG/build
