Description

technical field [0001] The invention relates to abnormal target detection technology, in particular to an abnormal target detection method based on an optical multi-dimensional information integrated perception system. Background technique [0002] The optical multi-dimensional information integrated perception system is a new type of optical detection technology that integrates "imaging, spectrum, polarization, and perception" for multi-dimensional information acquisition. It can simultaneously acquire the data hypercube of the measured target, and the data hypercube contains two-dimensional spatial information. , the spectral information of each dimension in the image and the polarization state information of each spectral segment. Spectral images have the characteristics of high spectral resolution, map-spectrum integration, and multiple spectral channels, which can exert great advantages in target detection and recognition. High application value. Abnormal target detec...
