    Abstract: In one embodiment, a computing system may access a first image and a second image of at least a common portion of an environment while a light emission with a predetermined emission pattern is projected by a projector. The first and second images are respectively captured by a first and a second detector that are respectively separated from the projector by a first and a second distance. The system may determine that a first portion of the first image corresponds to a second portion of the second image. The system may compute, using triangulation, a first depth value associated with the first portion and a second depth value associated with the second portion. The system may determine that the first and second depth values match in accordance with one or more predetermined criteria, and generate a depth map of the environment based on at least one of the depth values.

    Abstract: 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.

    Abstract: 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.

    Abstract: Apparatus for generating a dynamic structured light pattern for optical tracking in three-dimensional space, comprises an array of lasers, such as a VCSEL laser array, to project light in a pattern into a three-dimensional space; and an optical element or elements arranged in cells. The cells are aligned with subsets of the laser array, and each cell individually applies a modulation, in particular an intensity modulation, to light from the laser or lasers of the subset, to provide a distinguishable and separately controllable part of the dynamic structured light pattern. A method of generating a structured light pattern is disclosed, in which light is provided from an array of lasers, and light is individually projected from subsets of the array of lasers to provide differentiated parts of the structured light pattern.

    Abstract: A tracking system generates a structured light pattern in a local area. The system includes an array of lasers that generate light. The array of lasers includes a plurality of lasers and an optical element. The plurality of lasers are grouped into at least two subsets of lasers, and each of the at least two subsets of lasers is independently switchable. The optical element includes a plurality of cells that are each aligned with a respective subset of the array of lasers. Each cell receives light from a corresponding laser of the array of lasers, and each cell individually applies a modulation to the received light passing through the cell to form a corresponding portion of the structured light pattern that is projected onto a local area.
