Multi-spectral imaging acquisition and spectral reconstruction using monochromatic camera and narrow-band filters
Multi-spectral imaging technology, integrated wrth the capabilities of spatial imaging and spectral detecting, can acquire both spatial information and spectral information simultaneously, thus it is highly emphasized in acquisition and process of image. Based on the narrow band multi-spectral imaging technology a eight channel multi-spectral imaging system is set up which can acquire eight images in real time and eight Spectral responses ranging from 420 nm to 940 nm for a certain element. Each image must be aligned before more spectral reflectance can be obtained by interpolation .After calculation, spectral reflectance and related color parameter of each point can be obtained. The experiment indicated the interpolation by cube spine functions proved effective which could simulated spectral characteristics precisely at a certain degree. The system can be widely used in the field of moving target recognition and accurate color reproductions for acts.
