Claim 6:
7. A method for operating a vehicle measurement system consisting of a base unit, a support structure affixed to said base unit, and a pair of optical projection systems carried in a spaced arrangement in a common frame of reference by said support structure, each optical projection system including an optical projector carried by a multi-axis gimbal mounting structure located at a known location within a common reference frame, comprising:
selecting an origin point on a vehicle undergoing a service or inspection in operative proximity to said vehicle measurement system;
projecting a first illuminating beam of light from a first optical projector in said pair along a first projection axis;
orienting said first optical projection system by driving a first associated multi-axis gimbal mounting structure to align said first projection axis with said selected origin point such that said first illuminating beam of light illuminates said selected origin point;
projecting a second illuminating beam of light from a second optical projector in said pair along a second projection axis;
orienting said second optical projection system by driving a second associated multi-axis gimbal mounting structure to align said second projection axis with said selected origin point, such that said second illuminating beam of light illuminates said selected origin point;
identifying orientations of said first and second projection axes within said common frame of reference; and
calculating a position of said selected origin point within said common frame of reference using each of said identified orientations and said known locations of said multi-axis gimbal mounting structures for each of said first and second optical projection systems;
determining an orientation of said vehicle within said common frame of reference;
calculating a placement location in said common frame of reference relative to said vehicle orientation and said position of said selected origin point on said vehicle;
re-orienting said associated projection axis at least one of said optical projection systems by driving said associated multi-axis gimbal mounting structures to align said associated projection axis with said calculated placement location;
illuminating said calculated placement location with at least one of said first and second illuminating beams of light;
placing an ADAS sensor system calibration or alignment target at said illuminated placement location; and
conducting a vehicle ADAS sensor system calibration or inspection utilizing said placed calibration or alignment target.
