Vehicle dimensional measuring system

摘要

The present invention relates to a vehicle measuring apparatus for establishing baselines and dimensionally measuring a vehicle's upper and lower structure, without requiring the use of a fix mechanical grid mechanism. A method is presented which includes having a pre calibrated portable gauge (52) placed to a selected point on the vehicle with a squaring device (66) on gauge (52) positioned outwardly of the vehicle and having a light source (20) placed on or in proximity to the vehicle for projecting a plane of light (90 or 92) to align to squaring device (66). This alignment establishes a light beam baseline at a predetermined dimensional value with respect to the vehicle. Once the baseline is established measurements of the vehicle's upper or lower body may be determined by placing a portable gauge (52) relative to a point on the vehicle and using squaring device (66) to square the alignment of gauge (52) to the selected baseline.
