Abstract

The invention relates to a surface temperature information fusion method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring multi-source surface temperature information of a target region, wherein the multi-source surface temperature information at least comprises first surface temperature information and second surface temperature information,the first surface temperature information is surface temperature data of each day of clear sky, and the spatial scale of the first surface temperature information is less than that of the second surface temperature information; and carrying out temporal-spatial fusion on the first surface temperature information and the second surface temperature information according to the spatial scale of thefirst surface temperature information, and calculating fused surface temperature information of the target region. By the adoption of the method, the accuracy of the fused surface temperature information can be improved.

Description

technical field [0001] The present application relates to the field of satellite remote sensing technology, in particular to a method, device, computer equipment and storage medium for obtaining surface temperature information. Background technique [0002] Surface temperature information is an important state parameter for studying water, energy cycles, and environmental changes, and is widely used in research fields such as hydrology, meteorology, climate change, and environmental monitoring. Traditional land surface temperature information observations are often carried out on a point scale, which cannot provide continuous observations in time and space. The advancement of remote sensing technology has broken through this limitation, making it possible to obtain land surface temperature information on a wide range of different time scales and spatial scales (referred to as space-time scales). [0003] The remote sensing data of different satellite sensors have different ...
