YOLOv8+Deepsort+PyQt+GUI 语义分割+目标检测+姿态识别三者合一（集成于一套系统）综合视觉分析系统

综合视觉分析系统

技术栈：

YOLOv8：用于目标检测，是一个快速且准确的目标检测框架。
DeepSORT：用于目标跟踪，结合了深度学习特征提取和卡尔曼滤波器来预测目标轨迹。
GUI：提供一个直观易用的图形用户界面，使得非技术用户也能方便地使用该系统。
语义分割：通过YOLOv8或其他语义分割算法，可以区分图像中的不同区域或对象，并赋予它们特定的标签。
姿态识别：利用深度学习模型来识别物体或人体的姿态，如关键点的位置等。

功能描述：

目标检测与分类：系统能够识别视频或图像中的特定对象，并对其进行分类。
目标跟踪：使用DeepSORT算法，可以在连续的视频帧中持续跟踪已识别的对象。
语义分割：系统不仅限于检测对象边界框，还能区分图像的不同部分，例如船只及其背景。
姿态识别：能够识别目标对象的姿态，对于人形目标来说，可以检测出肢体的关键点位置，对于其他类型的目标，则可以根据应用场景定制姿态识别功能。
实时展示与交互：通过GUI，用户可以实时查看处理结果，并与系统进行交互，比如调整参数、保存结果等。

应用场景：

安全监控：在机场、车站等人流密集场所，帮助识别异常行为或可疑人物。
智能交通管理：监控道路情况，识别车辆、行人等，并进行交通流量管理。
工业自动化：在生产线上，用于质量控制，识别产品缺陷。
无人机监控：在海上或空中，用于船只或飞行物的自动识别与跟踪。

优势：

高效性：由于采用了先进的深度学习模型，系统能够以较高的帧率处理视频数据。
准确性：通过优化后的模型，系统能更准确地区分不同的对象和背景。
易用性：图形用户界面使得配置和操作变得简单，降低了用户的使用门槛。

这样的系统可以为多种行业提供强大的视觉分析能力，具有广泛的应用前景。
