摘要

On the basis of the limitations of LED visible light image (LED-VLI) extraction methods, the relationship of the satellite LED-VLI information and the ground substance and structure spectrum is analyzed to form a space angle model. The limitations of existing algorithms on LED-VLI data processing are also analyzed. The mathematical performance of the space angle-based algorithm in LED-VLI processing is evaluated through computer simulation and experiments, thereby providing useful information for the selection of mathematical processes and data mining tools, which can facilitate further development and research of LED-VLI.
