Abstract:
A method of classifying an object location of a 3-D object to a side of a transportation vehicle, said transportation vehicle moving along a front-to-rear directional axis and having a remote sensor mounted at a predetermined reference point, said method comprising the steps of:identifying a set of detection points substantially to said side of said transportation vehicle using said remote sensor; finding a detection point having a closest range to said vehicle reference point; classifying said object as on-center if a position Ynear along said directional axis corresponding to said closest-range detection point is within a predetermined threshold distance from a position Yzero along said directional axis corresponding to said predetermined reference point; if not on-center, then classifying said object as spanning if a first position Y1 along said directional axis and a second position Y2 along said directional axis are on opposite sides of said position Yzero; if not spanning, then classifying said object as front if any particular detection point is forward of said position Yzero; and if not spanning, then classifying said object as rear if any particular detection point is rearward of said position Yzero.
