Abstract

For accurate color and spectral reflectance reproduction, we propose a novel eleven-band acquisition system using a nine-view stereo camera. The proposed system consists of eight monochrome cameras with eight different narrow band-pass filters and an RGB camera. To generate an eleven-band image, the shapes of the nine captured stereo images are transformed to correct registration displacement caused by stereo parallax. In the process of correspondence search between stereo images, the phase-only correlation method (POC) is used. The most significant point of our method is that the captured RGB image is converted into narrow-band images for accurate correspondence search. The detected corresponding points are used for estimating parameters of image transformation and an eleven-band image is generated. By comparing with conventional method, experimental results show that the accuracy of correspondence detection and spectral reflection estimation is improved
