The debate over the capabilities of both will continue to rage. Whilst it seems agreed that ultrasonic sensors are not intelligent enough to fulfil the requirements, radar or microwave sensors may determine the difference between a pedestrian and street furniture. Detecting a VRU approaching a stationary vehicle represents a different challenge, and the ability of a sensor to pick-up a protective clothed and helmeted motorcyclist or hooded pedestrian is debateable. ACSS supply a tested AI camera solution. Cameras which run video scene analysis on the blind spot area and pick out the human frame (shoulders, head, neck) offer the best method of detection by alerting the driver and displaying the view on an in-cab monitor. Cameras may get dirty and need cleaning yes, but there’s no arguing with what you can see with your own eyes on a screen!
