Rectification method for two-dimensional camera array by using parallelizing locus of feature points

Abstract

We have developed an effective rectification method that has a pixel error of less than 0.25 of a pixel for use in two-dimensional multi-camera arrays. Rectification and correction are important for free view-point imaging and multi-view coding in the field of image-based rendering (IBR). In the computer vision field, a number of rectification methods for binocular/trinocular stereo camera setups have been develpopd and used. However, not many multi-camera array rectifications methods have been developed.
