1. A target alignment system for calibrating a safety sensor, the safety sensor is mounted upon a vehicle which is positioned upon a horizontal surface, the vehicle having a vehicle front, a vehicle first side, a vehicle second side, a vehicle rear, a plurality of wheels including a pair of front wheels, and a vehicle center line that extends longitudinally and centrally through the vehicle, the front wheels comprising a first front wheel at the vehicle first side and a second front wheel disposed at the vehicle second side, each of the plurality of wheels has a wheel center, the safety sensor having a calibration target and an optimum target position in line with the vehicle center line upon which placement of the calibration target allows accurate calibration of the safety sensor, the optimum target position corresponding to a location upon the horizontal surface, the target alignment system comprising:
a pair of target alignment assemblies comprising a first target assembly and a second target assembly, each target assembly having a target face, the first and second target assemblies are positioned upon the horizontal surface ahead of the vehicle front, with the vehicle center line extending between the first target assembly and the second target assembly;
a plurality of wheel-mounted visible guide projectors comprising a first front visual guide projector and a second front visual guide projector, the first front visual guide projector and the second front visual guide projector are each detachably secured to the first front wheel and the second front wheel respectively at a position aligned with the wheel center thereof, the first front visual guide projector and the second front visual guide projector are adapted to project a first longitudinal guide line and a second longitudinal guide line respectively, the first longitudinal guide line and the second longitudinal guide line are projected downwardly upon the horizontal surface in parallel with the vehicle central line, and are further projected forwardly past the vehicle front to align with the first and second target assemblies respectively; and
a center visual guide projector adapted to project a center guide line which is equidistant between the first and second longitudinal guide lines, is colinear with the vehicle center line, and which extends along the horizontal surface towards the vehicle, the center guide line allows the optimum target position to be located upon the horizontal surface in line with the vehicle center line.
