Description

Technical field [0001] The invention relates to an airborne multi-channel hyperspectral camera circuit integration system, in particular to an airborne application to provide multiple hyperspectral cameras with power output, communication control, data transmission, data storage, data quick view, data synchronization, A stable circuit integrated system. Background technique [0002] The hyperspectral camera acquires the solar radiation reflected by ground objects or its own radiation with high spectral resolution. This technology can not only perform morphological imaging of ground objects, but also obtain the spectral information of each pixel. Therefore, it can analyze and identify the observation target from two aspects: space matching and spectral matching, thereby revealing the spectrum of various ground objects Characteristics, existence, and material composition. The application of hyperspectral cameras directly meets the needs of land management, urban planning, agricul...
