A target system and method for photogrammetry using a target holder with an aperture at least partially therethrough to precisely position a target assembly therein for use in determining geometric properties of an object.
Claims7
A target mounting system for a retroreflective target, the system comprising:
- an elongated body having an upper portion with a generally cylindrical aperture at least partially therethrough and a lower tubular portion;
- a ring having a nest therein, the ring sized and shaped to fit within the aperture such that the ring outer surface engages an interior surface of said aperture and fits within said aperture such that a top surface of the ring is generally flush with an outer surface of said elongated body;
- aperture including a face surface at an end of said aperture opposing said outer surface of said elongated body, the ring sized and shaped to fit within the aperture such that at least one surface of the face engages at least one lower surface of the ring;
- and
- a target paper sized and shaped to engage and fit between the face surface and at least one surface of the ring within said aperture.
