Abstract

The present application relates to a multispectral imaging method, device and device for encoding and compressing based on dispersion. The method includes: imaging a mask based on a high-resolution lens provided with a glass having a predetermined angle with the optical axis to obtain an image in the horizontal direction. Generate mask images of different spectra with different offsets, superimpose the collected mask images to obtain a multi-spectral film mask, and collect the field of view with the camera attached to the multi-spectral film mask under white light to obtain the scene after dispersion coding image and under the spectrum segment to be reconstructed, perform vectorization calculation on the scene image, and obtain uncoded images of different spectrums when the number of calculations reaches the number of iterations. This solves the problem that ordinary cameras cannot collect dynamic, high-spatial-resolution spectral information in one shot with a simple system. By constructing an imaging system and executing reconstruction algorithms to distinguish fine features of different spectral bands, the reconstruction after one shot is improved. Multispectral high resolution image capability.

Description

technical field [0001] The present application relates to the technical field of spectral imaging, and in particular, to a multi-spectral imaging method, device and device for coding and compression based on dispersion. Background technique [0002] The ordinary camera collects the light intensity information of the three colors of red, green and blue in nature through a specific mode, and performs imaging on the sensor. However, in the fields of medical screening and ground remote sensing, there are often high requirements for the precise spectrum of objects displayed to the world, and ordinary cameras that only contain three color channels can no longer meet the requirements. [0003] A series of hyperspectral cameras have now emerged, using different methods to improve spectral resolution, that is, the ability to distinguish fine features in different spectral bands. The data they acquire are three-dimensional data cubes containing two-dimensional spatial intensity infor...
