基于YOLO系列与PyQt5的夜间红外小目标检测系统全流程解析目标检测是计算机视觉领域的核心任务之一，旨在从图像或视频中定位并识别出感兴趣的目标。其原理通常基于深度学习模型，通过卷积神经网络提取特征，并利用回归或分类头输出目标的位置与类别。这项技术的价值在于能自动化完成海量视觉数据的分析，极大地提升了安防监控、自动驾驶、工业质检等场景的效率和精度。在众多应用场景中，夜间或低光照环境下的目标检测尤为关键且富有挑战。本文聚焦于利用红外热成像技术解决这一难题，并重点探讨了如何集成YOLO系列算法与PyQt5框架，构建一套完整的红外小目标检测系统。该系统通过引入Mosaic数阅读详情

RT，按照下面的代码实现了界面的拖拽和缩放，但是界面的功能按键不能用了，好像一直在def nativeEvent(self,eventType,message)事件中循环，请教大家怎么解决。
下面是代码：
