Description

technical field [0001] The invention relates to the technical field of image acquisition and processing, in particular to an unmanned aerial vehicle-mounted light and small multi-spectral imaging system and an imaging method thereof. Background technique [0002] In recent years, with the development of UAV technology, the method of image acquisition by UAV has rapidly become popular in the market due to its advantages of convenience, quickness and low cost. Due to the advantages of high geometric accuracy, multispectral imaging can effectively restore high-quality images during the large-scale flight shooting process of UAVs. However, in the process of processing spectral information in the existing multispectral imaging technology, independent filters should be set for different bands of spectra, which leads to complex system configuration, and with the change of the noise source in the spectral information, the preset Filters are also sometimes unable to perform effectiv...
