To improve the fusion accuracy of multi-modal data in the field of autonomous driving this paper proposes a spatiotemporal synchronization technology techinal scheme for Light Detection and Ranging (LiDAR) and camera. By adopt a method of estimating and adjusting the offset, it calulates the time of the trigger for the camera exposure, and adjusts the offset time of the trigger for the camera exposure thereby controlling LiDAR and camera to scan and the same target at the same time. The results show that the proposed scheme significantly improves the fusion accuraly of poirt cloud data and images, verifying the feasibility and effectiveness of the technical scheme.
