PEDESTRIAN WARNING WITH LIGHT SPECTRUM THAT DOES NOT AFFECT CAMERA BASED OBJECT DETECTION AT NIGHT

Abstract: a pedestrian warning system for a work vehicle at a worksite that includes a sensor system that captures images of an identified target located at the worksite. an electronic data processor is communicatively coupled to the sensor system, and the electronic data processor determines whether the identified target from the captured image is an intended target based on one or more identifying characteristics associated with the identified target. when the intended target is identified, an alert directed to the intended target is generated that includes operation of one or more lights mounted on the work vehicle. the one or more lights operate in a light spectrum range that is not visible by the sensor system. the sensor system may include an optical filter to block light that corresponds to the light spectrum range of the one or more lights. the lights may operate in a strobing function.
