Abstract

The invention discloses a hyperspectral imaging system combining chromatic aberration blurred imaging and image reconstruction technologies, and the system comprises a chromatic aberration blurred imaging subsystem which comprises an imaging lens and a CMOS camera, the central axis of the imaging lens and the central axis of the CMOS camera are arranged in an aligned manner, and the imaging lens has axial high chromatic aberration in a visible light band or an infrared light band; the CMOS camera is used for collecting chromatic aberration blurred images under different image distances; an image processing unit is used for stacking the chromatic aberration blurred images to form a chromatic aberration blurred image cube, and based on a spectral image cube degradation model, in combinationwith the wavelength image distance relation curve and the point spread function library, the spectral image cube is reconstructed by using a sequence image deconvolution algorithm. The hyperspectral imaging system disclosed by the invention has the advantages of simple structure, high light energy utilization rate, high detection speed and the like, so that a high-sensitivity, rapid and miniaturized detection means is provided for spatial spectral information perception and specific identification of a target object in a special occasion.

Description

technical field [0001] The invention relates to the field of spectral imaging, in particular to a hyperspectral imaging system combining chromatic aberration blur imaging and image reconstruction technology. Background technique [0002] Spectroscopy Imaging technology is the product of the combination of spectral technology and imaging technology. It can detect the two-dimensional spatial shape information and one-dimensional spectral information of the target at the same time. Therefore, this "map-in-one" technology is widely used in geological resource exploration, crop vegetation observation, meteorological observation, atmospheric and water body monitoring, food analysis and other fields. [0003] At present, the spectroscopic methods used in commercial and satellite-loaded spectral imagers are mainly two types: prism / grating dispersion type and interference type. Traditional spectral imaging has mutual constraints in terms of spatial resolution, spectral resolution, s...
