Description

technical field [0001] The present application relates to the technical field of remote sensing satellite images, in particular to a method and electronic equipment for avoiding water body flares in optical remote sensing satellite images. Background technique [0002] Gaojing-1 remote sensing satellite constellation plays an important role in military defense, resource exploration, environmental monitoring and other fields by virtue of its advantages of strong mobility, diverse collection modes, and short revisit cycle. It is the core of the commercial remote sensing satellite market such as Gaojing-1, and water application is an important application field. Since optical remote sensing satellites use their camera loads to collect solar reflection radiation energy from the surface of the observation target to achieve remote sensing purposes, when the satellite images a water body area, especially a calm water surface, if the satellite observation vector and the sun incident...
