Patent number: 10049460Abstract: An object is identified or tracked within a volume by projecting a light beam encoded with one or more predefined properties to have a predefined optical structure into the volume. A detector captures light from the predefined optical structure reflected from the volume. By analyzing one or more characteristics of light from the predefined optical structure reflected from the object, the object is segmented from the volume.Type: GrantFiled: February 24, 2016Date of Patent: August 14, 2018Assignee: Facebook, Inc.Inventors: Nitay Romano, Nadav Grossinger

Patent number: 9947098Abstract: A solution for generating a 3D representation of an object in a scene is provided. A depth map representation of the object is combined with a reflectivity map representation of the object to generate the 3D representation of the object. The 3D representation of the object provides more complete and accurate information of the object. An image of the object is illuminated by structured light and is captured. Pattern features rendered in the captured image of the object are analyzed to derive a depth map representation and a reflectivity map representation of the illuminated object. The depth map representation provides depth information while the reflectivity map representation provides surface information (e.g., reflectivity) of the illuminated object. The 3D representation of the object can be enhanced with additional illumination projected onto the object and additional images of the object.Type: GrantFiled: May 13, 2016Date of Patent: April 17, 2018Assignee: Facebook, Inc.Inventors: Nitay Romano, Nadav Grossinger

Patent number: 9934574Abstract: To determine depth of an object within a volume, structured light is projected into the volume. The structured light comprises a pattern over which intensity of the light varies. A sensor detects light from the volume and uses variations in intensity of the detected light to correlate the detected light with the pattern. Based on the correlation, depth of objects within the volume is determined.Type: GrantFiled: February 24, 2016Date of Patent: April 3, 2018Assignee: Facebook, Inc.Inventors: Nadav Grossinger, Nitay Romano

Patent number: 9523771Abstract: A detector for optical detection of location within a volume, comprises a beam source for shining a structured light pattern on the volume and a digital detector having detection pixels of a given size. The light pattern, when shone into the volume and reflected back to the detection pixels, has a brightness distribution with a peak and a surrounding brightness structure. Now often the peak may be smaller than the pixel size although the overall distribution of the brightness extends over multiple pixels. The system includes an electronic processor for assessing a distribution of brightness among the neighboring pixels to infer a location of the peak within a region smaller than the size of the central pixel on which it falls, thus giving sub-pixel resolution.Type: GrantFiled: January 13, 2015Date of Patent: December 20, 2016Assignee: Facebook, Inc.Inventors: Nitay Romano, Nadav Grossinger, Emil Alon, Yair Alpern
