Abstract:

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.
