Abstract:
A method of classifying an object type of a 3-D object sensed by a remote sensor for detecting objects to a side of a transportation vehicle, said transportation vehicle moving along a front-to-rear directional axis, said remote sensor being mounted at a predetermined reference point on said transportation vehicle, said method comprising the steps of:identifying a set of detection points substantially to said side of said transportation vehicle using said remote sensor; identifying a closest one of said detection points to said remote sensor; if said closest one of said detection points is at a substantially perpendicular direction from said remote sensor, then: determining a size of said object in response to an area defined by locations of said set of detection points; comparing said size of said object with a size threshold; and if said size is less than said size threshold then classifying said object as a stationary object.
