POSITION MARKING AND REFERENCE METHOD AND SYSTEM FOR THE PRACTICE
First Claim
1. A method for position marking of an object, said method comprising:
- (a) calibrating position tracking information and direction on the object from global or local reference beacons to yield an object internal coordinate frame reference;
(b) obtaining local coordinates for two or more points (P1, P2 . . . PN) on the object from the object internal coordinate frame reference to yield an obtained position location information for the object;
(c) determining a direction of orientation from the two or more points for the object to yield a determined direction of orientation of the object; and
(d) calculating a translation value of the object between the determined direction of orientation of said object and the obtained position location information for the position marking of the object.

Abstract
A method and system are provided for position marking to register precise locations on a stationary objects in space, and to refer back to the locations that same precise location at a later time, while establishing a local coordinate system without consideration for the global location or orientation of the object, thereby ensuring the object does not need to be re-positioned or re-orientated before marking and referring to any object'"'"'s locations. The problem that a local coordinate reference system based on reference beacons is not correlated to the object'"'"'s reference frame is addressed through a novel calibration method. By eliminating consideration for coordinate setup and the need to physically move the object in the operating space, a more robust measurement is achieved that replaces such conventional steps with an easy to conduct calibration process that reduces the chance for human error.
