Time Synchronization Solution for Multi-Source Sensor Systems

Nanosecond-level time synchronization across LiDAR, cameras, and IMUs eliminates timestamp divergence in multi-sensor fusion. Combining hardware pulse triggers with Linux kernel timestamp refinement, the solution achieves <100 ns alignment for UART and pulse-based devices. Deployed on edge computing platforms, this synchronization layer enables raw data coherence critical for SLAM motion correction and V2X cross-system collaboration.
