Assignee: HUNTER ENGINEERING COMPANY
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A vehicle measurement system instrumentation structure, comprising:
a base unit;
a camera support structure affixed to said base unit, said camera support structure carrying a set of camera modules configured to acquire images associated with a vehicle undergoing measurement;
a pair of optical projection systems carried in a spaced arrangement by said camera support structure, each optical projection system in said pair including at least one optical projector defining an associated projection axis originating at a known location within a common reference frame, and a mounting structure for rotational movement of said at least one optical projector about at least two axes (X, Y, Z);
a processing system operatively coupled to said pair of optical projection systems and to said set of camera modules, said processing system having a processor configured with a set of instructions
to evaluate data received from each of said optical projection systems to determine orientations of said associated projection axes;
to identify, from said known locations of said optical projectors, together with said determined orientations of said associated projection axes, an origin point of intersection between said projection axes within said common frame of reference;
to receive and evaluate said acquired images from said set of camera modules to determine a position and orientation of said vehicle within said common frame of reference; and
to control said optical projection systems to orient said projection axes to project said visible indicia to one or more placement locations relative to said vehicle based on at least said identified origin point of intersection between said projection axes and said determined position and orientation of said vehicle within said common frame of reference.
