家庭宠物行为监测工具

这是一个基于智能视觉技术的家庭宠物行为监测系统，能够自动识别宠物的进食、饮水和活动情况，并生成健康报告推送给主人。

项目特色

- 智能识别：使用YOLOv8深度学习模型识别宠物行为

- 实时监控：24小时不间断监测宠物活动状态

- 健康报告：自动生成日报，统计行为频率和时长

- 远程推送：通过邮件发送分析报告到手机

安装部署

1. 克隆项目并安装依赖

pip install -r requirements.txt

2. 下载YOLOv8模型文件到项目目录

3. 配置config.py文件

- 设置摄像头ID和分辨率

- 配置邮箱SMTP信息

- 调整行为识别阈值

使用方法

python main.py

系统将自动启动摄像头，开始监测宠物行为。每小时生成一次报告并发送到指定邮箱。

模块说明

- capture.py：摄像头图像采集

- detector.py：YOLO目标检测识别

- analyzer.py：行为分析和状态跟踪

- reporter.py：健康报告生成

- notifier.py：邮件推送服务

注意事项

- 确保摄像头正常工作且有足够光线

- 首次使用需要训练宠物适应摄像头环境

- 邮箱需开启SMTP服务并获取授权码

使用说明

系统启动后将自动执行以下流程：图像采集→目标检测→行为分析→数据统计→报告生成→邮件推送。

关键配置参数说明：EATING_DURATION控制进食判定时长，CONF_THRESHOLD调整检测精度，REPORT_INTERVAL设置报告频率。建议根据实际环境微调阈值以获得最佳效果。

如需扩展功能，可在analyzer.py中添加新行为类型，或在reporter.py中自定义报告格式。系统支持多种宠物类型识别，可通过修改PET_CLASSES配置添加新宠物品种。
