Abstract: A method and apparatus for performing inbuilt calibration of camera system that performs three-dimensional measurements and depth reconstruction are described. In one embodiment, the method includes displaying, using a projector of a capture device, a fiducial projection pattern in response to calibration of the capture device. The method may also include capturing, with a camera of the capture, an image of the fiducial projection pattern. The method may also include determining calibration coefficient values indicative of relative physical relationships of one or more components of the depth camera system based on analysis of the captured image of the fiducial projection pattern.

Abstract: In accordance with disclosed embodiments, there are provided systems, methods, and apparatuses for implementing a stereodepth camera using a VCSEL projector with a controlled projection lens. For instance, a depth camera is described having therein a Vertical-Cavity Surface-Emitting Laser projector (VCSEL projector) to emit a plurality of infrared beams; a moveable lens to control the focus of the plurality of infrared beams emitted from the VCSEL projector, in which the plurality of infrared beams are projected through the moveable lens to form a projected pattern projected onto a scene; stereoscopic image capture devices to capture stereoscopic imagery from the scene having the projected pattern projected thereupon; and processing circuitry to determine depth to an object in the scene based on the captured stereoscopic imagery from the scene having the projected pattern represented therein as projected from the VCSEL projector. Other related embodiments are disclosed.

Abstract: In accordance with disclosed embodiments, there are provided systems, methods, and apparatuses for implementing a stereo depth camera using a VCSEL projector with spatially and temporally interleaved patterns. For instance, a depth camera is described having therein a Vertical-Cavity Surface-Emitting Laser projector (VCSEL projector); in which the VCSEL projector embodies a VCSEL array, the VCSEL being comprised of a plurality of VCSEL elements divided into a plurality of individually addressable subsets of the plurality of VCSEL elements; processing circuitry to activate one or more of the individually addressable subsets of the plurality of VCSEL elements to cause the VCSEL projector to emit a plurality of infrared beams through a projection lens to form a projected pattern which is projected onto a scene; stereoscopic image capture devices to capture stereoscopic imagery from the scene having the projected pattern projected thereupon; and processing circuitry to determine depth to an object in the scene based on the captured stereoscopic imagery from the scene having the projected pattern represented therein as projected from the VCSEL projector. Other related embodiments are disclosed.

Abstract: Apparatus, computer-readable storage medium, and method associated with human computer interaction. In embodiments, a computing device may include a plurality of sensors, including a plurality of light sources and a camera, to create a three dimensional (3-D) interaction region within which to track individual finger positions of a user of the computing device. The light sources and the camera may be complementarily disposed for the camera to capture the finger or hand positions. The computing device may further include a 3-D interaction module configured to analyze the individual finger positions within the 3-D interaction region, the individual finger movements captured by the camera, to detect a gesture based on a result of the analysis, and to execute a user control action corresponding to the gesture detected. Other embodiments may be described and/or claimed.
