摘要
对当前城市热岛效应研究所采用的三类主要方法进行了分析,分别得出其优势和存在的不足,提出了一种基于微小型多旋翼无人机平台开发小尺度高分辨率地表温度场观测系统的创新思路,并通过对红外测温原理的研究,设计了热红外无人机地表温度场反演系统,开发了B/S架构的地表温度场反演软件,实现了红外图像实时传输、自动拼图、米级网格化地表温度场反演、实景地图叠加、历史数据回放和数据导出等功能;经多次飞行实践应用表明,该系统运行稳定、数据准确、投资少,机动灵活,使用方便,可弥补传统卫星遥感等观测手段的不足,为开展城市区域热环境精细化观测提供了一种新的技术平台与工具,也为气象无人机的应用开辟了一个新的方向。
The advantages and disadvantages of the three main methods used in the current urban heat island effect research are analyzed,and an innovative idea of developing a small-scale and high-resolution surface temperature field observation system based on a micro multi-rotor UAV platform is proposed.The inversion system of surface temperature field for thermal infrared unmanned aerial vehicle(UAV)is developed,and the inversion software based on B/S structure is developed.The functions of infrared image real-time transmission,automatic mosaic,meter-scale grid surface temperature field inversion,real-time map stacking,historical data playback and data export are realized.The practice of many flights shows that the system is stable in operation,accurate in data,less in investment,flexible in maneuverability and convenient in use.It can make up for the shortcomings of traditional satellite remote sensing and other observation means,and provides a new technical platform and tool for fine observation of urban thermal environment,and also opens up a new way for the application of meteorological UAV.
