New hardware circuit synchronizes lidar and camera data for roadside perception systems

By PulseAugur Editorial · [1 sources] ·

Researchers have developed an open-source hardware-triggered time synchronization circuit designed to accurately align data from multiple roadside sensors, specifically lidar and cameras. This modular system uses a lidar synchronization pulse as a reference to generate time-delayed trigger pulses for each camera, allowing for flexible adaptation to different sensor configurations. Experiments on a roadside system with lidar and three cameras demonstrated the circuit's ability to achieve robust and repeatable synchronization, maximizing cross-sensor consistency for improved environment perception. AI

IMPACT Improved sensor data alignment can enhance the accuracy and reliability of perception systems used in autonomous driving and smart city applications.
