2025-10-18

📋 系统环境

操作系统: Debian 12 (bookworm)

硬件: Intel i5-4520, 8GB内存, 512GB硬盘

摄像头: RTSP流 (rtsp://admin:admin@10.0.0.234:554/h264/ch0/main/av_stream)

🔍 第一步：环境检查

# 检查系统信息
cat /etc/os-release
uname -r

# 检查Python环境
python3 --version
pip3 --version

# 检查摄像头设备
lsusb | grep -i camera || echo "未检测到摄像头设备"
ls /dev/video* 2>/dev/null || echo "未找到视频设备"

# 检查网络连接
ping -c 3 8.8.8.8

# 检查磁盘空间
df -h /

🔧 第二步：安装系统依赖

# 更新包列表
apt update

# 安装基础开发工具
apt install -y build-essential cmake pkg-config

# 安装OpenCV依赖
apt install -y libjpeg-dev libtiff5-dev libpng-dev libavcodec-dev libavformat-dev libswscale-dev libv4l-dev libxvidcore-dev libx264-dev libgtk-3-dev libatlas-base-dev gfortran

# 安装其他工具
apt install -y wget curl git vim htop

# 安装Python开发包
apt install -y python3-dev python3-venv

📁 第三步：创建项目目录和虚拟环境

# 创建项目目录
mkdir -p /opt/face_recognition_system
cd /opt/face_recognition_system

# 创建虚拟环境
python3 -m venv face_env

# 激活虚拟环境
source face_env/bin/activate

# 升级pip
pip install --upgrade pip

🐍 第四步：安装Python依赖包

# 确保在项目目录和虚拟环境中
cd /opt/face_recognition_system
source face_env/bin/activate

# 安装核心依赖包
pip install face_recognition opencv-python flask flask-cors pillow numpy requests imutils

# 验证安装
python -c "import face_recognition, cv2, flask; print('所有包安装成功！')"

📂 第五步：创建项目目录结构

# 确保在项目目录中
cd /opt/face_recognition_system

# 创建目录结构
mkdir -p {static,templates,uploads,logs,database}

# 查看目录结构
ls -la

💻 第六步：创建主程序文件

# 创建支持RTSP的主程序
cat > app.py << 'EOF'
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
