실외 게임용 증강현실 서비스를 위한 실시간 지역 정보 매칭

Abstract

Location based service and AR(Augmented Reality) techniques have been one of the most important areas incurrent computer games and mobile application. This paper presents GPU(Graphics Process Unit) based imagerecognition system for outdoor games and mobile application. In learning stage, we extract features from inputimage sequence and convert them into meta information in database. User captures then a query image that issent to GPU based server system. The proposed system build a descriptor codebook using BRISK and SURFdescriptors, and employs codebook with re-ranking information based on homography.
