Velodyne LiDAR announced that it has collaborated with LSA Autonomy, which today unveiled the Overhead Wire Laser-Detector – the OWL – a 3D LiDAR sensor-based technology and software system that marks a quantum leap forward in the detection of overhead obstacles for oversize transports.


By applying LSA Autonomy’s sensor processing software to Velodyne LiDAR’s HDL-32E real-time 3D LiDAR sensor, the OWL detects any overhanging obstacle that might interfere with special transports of oversize objects. When clearances are insufficient, the system alerts the operator in real-time with audible and visual warnings, while providing photographic imaging for clarity.


Currently, transport companies use measured poles to determine whether an oversize load will be able to safely travel under a potential obstacle. Some companies have cars with telescopic poles attached to the front bumpers, while other companies have employees who walk while carrying poles of the necessary length.


“Logistically speaking, the OWL will have a transformative impact on the planning and actual transport of oversized loads,” said Mike Grinnell, director of operations for LSA Autonomy. “The reductions of cost, time, and risk to people, product, infrastructure and reputation will be enormous.”
