Abstract

The invention relates to an aerial remote sensing estimation method of a city complete surface temperature, and belongs to a city surface temperature remote sensing estimation research field. The aerial remote sensing estimation method comprises steps that a flight route is determined according to a destination; according to the predetermined flight route, a flight test is carried out, and a city surface thermal infrared image is acquired; the thermal infrared image is preprocessed; and the complete surface temperature estimation is carried out. By considering a complicated city three-dimensional structure and difficulty of conventional remote sensing ways of inability of acquiring the complete surface temperature directly caused by large temperature differences among underlying surface components and limited sensor visual angles, the simple and effective aerial remote sensing estimation method of the city complete surface temperature is provided. The aerial remote sensing estimation method is advantageous in that adaptability is strong, and the city complete surface temperature is estimated accurately, and therefore requirements of actual production can be satisfied.

Description

technical field [0001] The invention relates to an aerial remote sensing estimation method of urban complete surface temperature, which belongs to the research field of urban surface temperature remote sensing estimation. Background technique [0002] Urban surface temperature is a key parameter reflecting the radiation and energy balance of the underlying surface of the city, and plays an important role in the study of urban climate and environment. Thermal infrared remote sensing is an important means to obtain large-scale urban surface temperature. However, thermal infrared remote sensing can usually only obtain the thermal radiation information of the underlying surface in one or several specific directions (that is, the directional radiation temperature θ and are the observed zenith angle and azimuth angle), and the thermal radiation information obtained at different angles is quite different, it is difficult to obtain the true temperature of the complete urban unde...
