Design and Performance Evaluation of a PatchMatch Stereo FPGA Accelerator

Abstract

PatchMatch Multi-View Stereo (MVS) is a method generating a depth map from multi-view images. The drawback of PatchMatch MVS is its large computational amount. We presents an FPGA accelerator for PatchMatch MVS for high-speed and low-power; this is designed using OpenCL that allows users a high-level description like C/C++ for efficient design.
