Abstract
3D laser radar is a high-speed figure recognition system that measures the position and speed of objects in real time. It can function despite poor weather conditions as it works by measuring the distance to an object with a laser pulse. By applying 3D laser radar for use in road and rail traffic safety, IHI has realized a system that can measure the position and speed of vehicles and pedestrians. Currently, more than 800 of these systems are in operation in Japan and this number will highly likely increase in future, contributing to improvements in traffic safety.
Keywords: Laser radar, obstacle detection, three-dimensional scanning, traffic safety, level crossing, vehicle, train, pedestrian, gondola, collision avoidance.
