本文主要是介绍基于YOLO开发构建红外场景下无人机航拍车辆实例分割检测识别分析系统，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
在我之前的博客中关于车辆检测、无人机航拍车辆检测、遥感车辆检测计数等都有实践性质的文章，感兴趣的话可以看下：
《基于目标检测的无人机航拍场景下小目标检测实践》
《基于YOLOv6m目标检测模型开发构建大雾天气下行人车辆检测识别分析系统》
《基于目标检测实现遥感场景下的车辆检测计数》
这里也是在做车辆相关的检测识别，只不过有两个不同点：
场景不同，这里的场景为红外场景下由无人机航拍获取的数据
目的效果不同，这里主要是开发构建车辆实例分割识别模型
首先看下效果图：
接下来看下数据集：
