修改概述:
新增摄像头画面中实时人物数量检测功能，优化目标识别后的人数统计与可视化展示
修改的详细描述
1.调整core/detector.py中的detect_frame函数：新增 “人物数量统计” 逻辑，在处理摄像头帧时，实时筛选检测结果中的 “person” 类目标并统计数量；
2.优化可视化展示：在摄像头画面中添加 “当前人物数量：X” 的文本标注，调整标注位置（画面底部），避免遮挡检测目标。
经过了什么样的测试?
1.操作系统：Windows 10/11、macOS 14、Ubuntu 22.04
2.Python 版本：3.8.5、3.9.13、3.10.8
运行效果
动图、视频、截图等
