In this paper, we propose a relocalization method for keyframe-based SLAM that enables real-time and accurate recovery from tracking failures. To realize an AR-based application in a real world situation, not only accurate camera tracking but also fast and accurate relocalization from tracking failure is required. The previous keyframe-based relocalization methods have some drawbacks with regard to...
We propose a novel 3D graphics architecture based on scan-line rendering. Scan-line rendering does not require a frame buffer and depth buffer, therefore it can reduce memory usage as compared with the widely used frame buffer architecture. On the other hand, scan-line rendering requires a huge volume of memory access. Some algorithms to solve this problem were proposed in the field of 2D graphics,...
