The embodiments described herein include a system and method for measuring a surface appearance of a surface. An appearance sensor is positionable about a surface and is configured to measure the surface appearance. A surface relationship sensor senses the distance between the appearance sensor and the surface. The appearance sensor is then positioned about the surface based on the sensed distance.

System and method for measuring surface appearance of a surface

Typically, paint film thickness is measured at a plurality of locations on a vehicle body by a hand-held sensor which is positioned by an operator at a position normal to the respective locations being sensed. This operation may be inaccurate and time-consuming because substantial reliance is placed upon the operator. The invention provides an apparatus for positioning a plurality of sensors in contact with a plurality of locations, respectively, on a non-planar surface such that each sensor is positioned normal to the non-planar surface at the respective location on the surface. The apparatus includes a movable fixture and a plurality of pistons carried by the movable fixture. Each of the pistons is movable independently with respect to the fixture. Each piston includes a distal end, and a sensor is pivotally mounted to each distal end. Each distal end is spring-biased away from the fixture, and each sensor includes at least two contact points for contacting the non-planar surface on opposing sides of the respective location for orienting the sensor in a position normal to the non-planar surface at the respective location.
