Abstract
This paper presents a novel multi-stereo camera system for robust indoor localization, leveraging point cloud data and temporal fusion techniques. The system integrates three synchronized stereo cameras to capture point clouds from multiple angles, enhancing coverage and improving point cloud density in complex indoor environments. By combining data from different perspectives and accumulating point clouds over time, the method mitigates the limitations in the short range of point clouds derived from stereo cameras, ensuring broader coverage for effective localization. To manage the computational complexity of large-scale point clouds and reduce noise in accumulated data, voxelization is applied to downsample the point clouds while preserving key geometric features. The localization process is driven by a predictive point cloud odometry method, refined through the Iterative Closest Point (ICP) algorithm. Experimental results demonstrate the system’s ability to achieve accurate localization within a pre-built LiDAR map. This study highlights the feasibility of using low-cost stereo camera systems as an alternative to LiDAR-based solutions for indoor localization.
