SAOG: Spatial-Attribute-Aware 3D Object Grounding via Visual Question Answering-Enhanced Reasoning

3D object grounding aims to identify the target object referred to by natural language instructions in the presence of multiple distractors. The task is inherently challenging, as it demands joint consideration of spatial relations and intrinsic object attributes to disambiguate the referred target from distractors. Co...

Does Online Gravity Estimation Matter? Revisiting a Silent Design Split in LiDAR-Inertial Odometry

LiDAR-inertial odometry (LIO) systems differ in whether they continue estimating gravity after initialization. We compare four gravity-bias state configurations in each of FAST-LIO2 and LIO-SAM, then separately test a gravity-direction factor. Across 12 dataset sequences evaluated with FAST-LIO2, fixing gravity under c...
