Photometric Consistency for Dual Fisheye Cameras

Back-to-back dual fisheye cameras are the most popular and cost-effective device to capture 360° images. However, inconsistent intensity and color between the pair of fisheye images often cause visible artifacts in the final 360° image. In this paper, we present a method to create photometric consistency between the two fisheye images. Specifically, we propose a loss function for image intensity compensation and a local color transfer model for color correction. Experimental results show that our method is able to correct the photometric inconsistency between dual fisheye images for high-quality 360circ imaging. ? 2020 IEEE.
