New method achieves joint multi-camera LiDAR calibration

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a novel two-stage framework for joint multi-camera LiDAR extrinsic calibration. This method first uses CMRNext for initial pairwise estimates and then refines them using a multi-frame bundle adjustment. The approach ensures system-level consistency by accounting for the geometric coupling in multi-camera setups, outperforming independent pairwise methods on both in-domain and out-of-domain datasets.

    Joint Multi-Camera LiDAR Extrinsic Calibration via Learned Pairwise Initialization and Geometric Refinement

    arXiv:2605.31576v1 Announce Type: new Abstract: Most learning-based camera-LiDAR calibration methods treat each camera-LiDAR pair independently, ignoring the rigid geometric coupling in multi-camera platforms. As a result, per-camera estimates may be individually accurate yet inc…

    Joint Multi-Camera LiDAR Extrinsic Calibration via Learned Pairwise Initialization and Geometric Refinement

    Most learning-based camera-LiDAR calibration methods treat each camera-LiDAR pair independently, ignoring the rigid geometric coupling in multi-camera platforms. As a result, per-camera estimates may be individually accurate yet inconsistent at the system level. We present a two-…
