Towards Accurate State Estimation: Motion Dynamics Kalman Filter for 3D Multi-Object Tracking

Read the original on arXiv Computer Vision →

The paper introduces a Motion Dynamics Kalman Filter (MD‑KF) for 3D multi‑object tracking that adapts to motion variation while keeping a single‑model structure. It improves state estimation by scaling motion components to reduce drift, especially for distant or occluded objects. Experiments on KITTI, Waymo Open Dataset, and real vehicle tests show MD‑KF matches multimodel KF performance with a 1.72× speedup.

A Multi-Modal Perception Pipeline for Object Detection and Tracking in Autonomous Racing

The paper introduces a multi‑modal late‑fusion perception pipeline for object detection and tracking in autonomous racing. It combines independent detections from cameras, LiDARs, and RADARs to produce timely and robust state estimates of surrounding vehicles. The tracking framework compensates for detection delays and incorporates vehicle dynamics and track layout knowledge, and its effectiveness is confirmed through real‑world experiments in diverse critical scenarios.

IMM-based Multiple Object Tracking using a State Prediction Neural Network

The paper introduces PR-IMM, a data‑driven state predictor‑based Interacting Multiple Model tracking method that integrates a transformer‑based prediction model with radar Doppler measurements. PR-IMM combines this prediction model with conventional CV, CA, and CT motion models, dynamically weighting their prior positions according to mode probabilities. Experiments demonstrate that PR-IMM reduces position‑estimation error by 57.3% compared to the standard IMM and by 16.5% compared to the prediction model alone, while also lowering ID switches by 25.3% and improving IDF1 by 9.6%.
