Abstract:
In this paper, we design, evaluate and compare two phase-based passive stereovision architectures. We present two approaches to implement phase-based correspondence search algorithms in real-time for sparse stereovision applications. The first approach enhances the accuracy of the 1D phase correlation method. The second approach optimizes the 2D phase correlation method at the cost of degradation in disparity estimation accuracy. We report experimental results that encourage the use of the proposed systems in a 3D imaging device dedicated to cover vision for blinds through cortical visual stimulation. FPGA implementation running at 200 fps is described.
