Abstract: A method of 3D measurement is performed using a first camera and a second camera located at different distances from the projector. The method includes projecting a known projection pattern that includes at least two non-crossing lines to form a first band and a second band on a surface of an object. The method includes recording first and second images of the object using the first and second cameras, respectively. The method includes determining a first longitudinal coordinate of a first point within the first band and a first vertical coordinate of the first point within the first band; determining a second longitudinal coordinate of the first point within the first band; and determining a second vertical coordinate of the first point within the first band. The method includes determining a final vertical coordinate of the first point by comparing the first longitudinal coordinate to the second longitudinal coordinate.

Abstract: A device for user enrollment is adapted to capture an image of a pattern projected on a target and distorted on the three-dimensional (3D) surface of the target, such as a human face, and an image of a two-dimensional (2D) surface of the target. The device can include an illumination unit adapted to project a patterned light onto the surface of the target in an invisible light wavelength, a 3D image capturing device to capture an image of a pattern projected on the target and distorted on the 3D surface of the target. The device can also include a 2D image capturing device adapted to capture an image of a 2D frontal view of the target in visible light. The device can also include an orientation unit that displays the face of the target in order to facilitate the positioning of the target within the proper fields of view.
