1. A vehicle measurement system, comprising:
- a pair of sensor units disposed in proximity to a vehicle inspection lane through which a moving vehicle passes, with one sensor unit of said pair on each opposite lateral side of said vehicle inspection lane;
wherein each sensor unit includes at least one displacement sensor system configured to acquire at least three displacement measurements associated with a rolling wheel assembly on an associated side of a vehicle moving through said vehicle inspection lane between said sensor units, each of said displacement measurements acquired along an associated measurement axis, each of said associated measurement axes vertically separated along a common vertical axis; and
wherein each of said sensor units is operatively coupled to convey said displacement measurements to a processing system configured with software instructions to utilize said displacement measurements to determine at least one measure of a vehicle characteristic.

Abstract
A vehicle measurement station utilizing at least one displacement sensor systems disposed on each opposite side of a sensor region of a vehicle inspection lane to acquire measurement data, associated with a vehicle passing through the sensor region. Each displacement sensor system is configured to acquire measurement data along at least three discrete and vertically spaced measurement axis in response to a trigger signal indicating the presence of a vehicle moving through the inspection lane. A processing system receives the acquired data for evaluation, identification of outlier data points, and for determining a measurement associated with a characteristic of the moving vehicle.
