Abstract

Dynamic Acquisition of multi-spectral light field image with high resolution, is a conundrum in Computational Photography. In this paper, we propose a multispectral imaging system based on multi-view light field rendering. The hardware system architecture consists of equidistantly fixed camera array and various spectral filters, and we use an algorithm based on frequency domain pyramid decomposition to calculate the disparity at different view angles. So we can realize the cross-channel image matching so as to obtain the single- view image under the multi-spectral channel and achieve the high-resolution real-time multi-spectral imaging.
