【算法介绍】
基于YOLOv8深度学习的120种犬类检测与识别系统是一款功能强大的工具，该系统利用YOLOv8深度学习框架，通过21583张图片的训练，实现了对120种犬类的精准检测与识别。
该系统基于Python与PyQt5开发，具有简洁的UI界面，支持图片、视频以及摄像头三种方式进行目标检测，并能够将检测结果进行保存。在检测过程中，系统能够实时显示目标位置、目标总数、置信度以及用时等信息，为用户提供直观、清晰的检测结果。
该系统在多个领域具有广泛的应用价值。在公共安全领域，警方和安保人员可以利用它快速识别搜救犬、警犬以及潜在的威胁性狗类，提高工作效率和响应速度。在宠物行业，它有助于宠物店、兽医诊所和动物收容所更准确地记录和管理犬只信息，提供更个性化的服务。此外，它还可以用于城市管理中监控流浪狗的数量和分布，处理公共卫生问题和安全风险，以及牧场和农场中牧羊犬的精准管理等。
总之，基于YOLOv8深度学习的120种犬类检测与识别系统是一款高效、准确、易用的工具，它的出现将极大地推动犬类检测与识别技术的发展，为多个领域带来便利和价值。

使用步骤：
（1）首先根据官方框架https://github.com/ultralytics/ultralytics安装教程安装好yolov8环境，并安装好pyqt5
（2）切换到自己安装的yolov8环境后，并切换到源码目录，执行python main.py即可运行启动界面，进行相应的操作即可
