Abstract
A three dimensional scanning apparatuses and methods of calibrating such apparatuses. The apparatus included a camera moveable along a first longitudinal axis, and a projector moveable along a second longitudinal axis which is parallel or coincident with the first longitudinal axis. Movement of one of the camera and projector along its corresponding longitudinal axis toward the other of the camera and projector causes the other of said camera and projector to move along its corresponding longitudinal axis toward the one of said camera and projector.
Claims27
A three dimensional scanning apparatus comprising:
- a camera moveable along a first longitudinal axis;
- and
- a projector moveable along a second longitudinal axis which is parallel or coincident with the first longitudinal axis, wherein movement of one of said camera and projector along its corresponding longitudinal axis toward the other of said camera and projector causes said other of said camera and projector to move along its corresponding longitudinal axis toward said one of said camera and projector.
A three dimensional scanning apparatus comprising:
- a first camera moveable along a first longitudinal axis;
- a second camera moveable along a second longitudinal axis which is parallel or coincident with the first longitudinal axis, wherein movement of said first camera along the first longitudinal axis toward the second camera causes the second camera to move toward the first camera along the second longitudinal axis;
- and
- a projector.
A method for calibrating the location of a camera and a projector for three dimensional scanning of an object, the method comprising:
- projecting a vertical line on the object;
- projecting a light beam parallel to an optical axis of said camera
- moving the camera along a first longitudinal axis toward a projector until said light beam intersects said line;
- and
- moving the projector synchronously with said moving of said camera toward the camera along a second longitudinal axis which is parallel or coincident with the first longitudinal axis.
A method for calibrating the location of two cameras for three dimensional scanning of an object, the method comprising:
- projecting a vertical line on the object;
- projecting a light beam parallel to an optical axis of a first camera
- moving the first camera along a first longitudinal axis toward a second camera until said light beam intersects said line;
- and
- moving the second camera synchroshously with said moving of said first camera toward the first camera along a second longitudinal axis which is parallel or coincident with the first longitudinal axis.
