Online Target-less Radar-LiDAR-Camera Extrinsic Calibration via Joint Optimization

Gunhee Shin, Yunsoo Kim, Chanhyuk Lee et al. · 2026

Fusing radar, LiDAR, and camera enables robust perception in diverse and adverse conditions, but the fusion performance critically depends on accurate extrinsic calibration among the three sensors. In this paper, we address the problem of online target-less extrinsic calibration for the radar-LiDAR-camera system. Exist …

Less Data, Better Timing: Student-Curriculum Coupling for VLM On-Policy Distillation in Temporal Video Grounding

Jiacheng Qiu, Yunsoo Kim, Ruichen Xu et al. · 2026

On-policy distillation (OPD) provides dense supervision directly on student-generated trajectories, making it an effective post-training strategy for vision-language models in temporal video grounding (TVG). However, existing pipelines typically construct the training curriculum from a fixed teacher and the initial stu …
