Configuration

OCR Engine Setup

OCR 食品包装识别支持多种方式，零配置即可使用。

方式一：AI 助手识别（推荐，零配置）

如果你使用 AI 助手（如 OpenClaw），直接发送食品包装图片：

[发送图片]
"录入这个食材，生产日期 2025-01-15"

助手会直接识别图片并录入，无需任何配置。

方式二：本地识别（命令行，免费）

使用 macOS 内置 Vision 框架，无需配置：

python3 scripts/food_analyzer.py --user <name> scan --image food.jpg --engine macos

方式三：云端识别（命令行，可选）

如需更高识别精度，配置云端 Vision API：

步骤 1：创建配置文件

cp data/user_config.example.yaml data/user_config.yaml

步骤 2：填入 API key

vision:
  api_key: "your-api-key"
  base_url: "https://api.moonshot.cn/v1"  # 或其他兼容 OpenAI 的 API
  model: "kimi-k2.5"

步骤 3：使用

python3 scripts/food_analyzer.py --user <name> scan --image food.jpg

支持的 API 提供商：

• Moonshot (Kimi)
• OpenAI
• 阿里 DashScope
• 其他兼容 OpenAI 接口的服务

说明：

• user_config.yaml 已被加入 .gitignore，不会意外提交
• 云端 OCR 仅在命令行模式下需要配置
• AI 助手模式始终优先使用助手内置的视觉能力
