Abstract

Stereo matching methods are typically divided into two types: area-based and feature-based methods. Area-based methods apply stereo matching to the entire image and are more widely used. However, since area-based methods calculate the matching points with block units for the whole image, real-time stereo matching of area based methods requires a significant amount of computing time. This paper proposes a line disparity map creation algorithm that can perform real-time stereo matching through GPGPU parallel processing based on OpenCL by improving the performance of the matching process.
