CalibSwitch: Observation-Driven Camera-LiDAR Extrinsic Recovery and Selective Maintenance for Multimodal Perception
CalibSwitch: Observation-Driven Camera-LiDAR Extrinsic Recovery and Selective Maintenance for Multimodal Perception
This research presents CalibSwitch, an observation-driven framework that separates absolute extrinsic recovery from selective state maintenance for camera-LiDAR perception on mobile robots.
The paper introduces CalibSwitch, a framework combining a cross-modal absolute extrinsic generator and a selective recurrent calibration policy to maintain sensor geometry on mobile robots without relying on numerical initial transforms or unconditional per-frame updates.

Paired geometry--observation uncertainty tests, two real-vehicle platforms, and 13.5-FPS single-camera Jetson execution demonstrate the system value of selective geometric-state maintenance for continuous perception.
