AI Technical Summary
Technical Problem
Conventional LiDAR SLAM systems face challenges in indoor environments due to ambiguous double-side issues with planar surfaces, leading to errors in pose estimation and map accuracy, and the computational burden of bundle adjustment methods.
Method used
A planar LiDAR SLAM framework that distinguishes the two sides of a planar object using vector normals and performs planar bundle adjustment to reduce errors, incorporating localization, local mapping, and PBA components to balance accuracy and computational cost.
Benefits of technology
The framework reduces pose errors and drift, enhances map accuracy, and accelerates undistortion and registration tasks, providing a more precise and efficient indoor mapping experience.
