Patent number: 9386299Abstract: A method including providing a device that projects a pattern of coherent radiation. The method further includes capturing a reference image of the pattern using an image sensor by projecting the pattern of the coherent radiation onto a reference surface and engendering a relative motion between the reference surface and the image sensor while capturing the reference image. The method also includes storing the reference image in a memory associated with the device.Type: GrantFiled: June 11, 2014Date of Patent: July 5, 2016Assignee: APPLE INC.Inventors: Alexander Shpunt, Dmitri Rais, Niv Galezer

Patent number: 9348423Abstract: A device for processing data includes a first input port for receiving color image data from a first image sensor and a second input port for receiving depth-related image data from a second image sensor. Processing circuitry generates a depth map using the depth-related image data. At least one output port conveys the depth map and the color image data to a host computer.Type: GrantFiled: August 25, 2014Date of Patent: May 24, 2016Assignee: APPLE INC.Inventors: Evgeny Spektor, Zafrir Mor, Dmitri Rais

Patent number: 9330324Abstract: A method for forming a three-dimensional (3D) map of an object, including illuminating the object from a light source so as to project a pattern onto the object, capturing an image of the pattern using an array of detector elements, and processing the captured image so as to measure respective offsets of elements of the pattern in the captured image relative to a reference pattern, the offsets including at least a first offset of a first element of the pattern and a second offset of a second element of the pattern, measured respectively in first and second, mutually-perpendicular directions in a plane of the array. The method further includes computing a correction factor in response to the first offset, applying the correction factor to the second offset so as to find a corrected offset, and computing depth coordinates of the object in response to the corrected offset.Type: GrantFiled: July 5, 2012Date of Patent: May 3, 2016Assignee: APPLE INC.Inventors: Daniel Cohen, Dmitri Rais, Erez Sali, Niv Galezer, Alexander Shpunt

Patent number: 8249334Abstract: A computer-implemented method includes receiving a depth map (30) of a scene containing a body of a humanoid subject (28). The depth map includes a matrix of pixels (32), each corresponding to a respective location in the scene and having a respective pixel value indicative of a distance from a reference location to the respective location. The depth map is segmented so as to find a contour (64) of the body. The contour is processed in order to identify a torso (70) and one or more limbs (76, 78, 80, 82) of the subject. An input is generated to control an application program running on a computer by analyzing a disposition of at least one of the identified limbs in the depth map.Type: GrantFiled: May 10, 2007Date of Patent: August 21, 2012Assignee: Primesense Ltd.Inventors: Tamir Berliner, Ziv Hendel, Alexander Shpunt, Jeffrey Danowitz, Dmitri Rais, Oren Mor, Michael Shpigelmacher
