Abstract

This paper presents a quantitative evaluation of a set of approaches for increasing the accuracy of an area-based stereo matching method. It is targeting real-time FPGA systems focused on low resource usage and maximized improvement per cost unit to enable concurrent processing. The approaches are applied to a resource optimized correspondence implementation and the individual and cumulative costs and improvements are assessed. A combination of the implemented approaches perform close to other area-matching implementations, but at substantially lower resource usage. Additionally, the limitation in image size associated with standard methods is removed. As fully piped complete on-chip solutions, all improvements are highly suitable for real-time stereo-vision systems.
