A three-dimensional (3D) image sensor module including: an oscillator configured to output a distortion-compensated oscillation frequency as a driving voltage of a sine wave biased with a bias voltage; an optical shutter configured to vary transmittance of reflective light reflected from a subject, according to the driving voltage, and to modulate the reflective light into at least two optical modulation signals having different phases; and an image generator configured to generate image data about the subject, the image data including depth information that is calculated based on a difference between the phases of the at least two optical modulation signals.

Enhanced methods and systems for generating both a geometry model and an optical-reflectance model (an object reconstruction model) for a physical object, based on a sparse set of images of the object under a sparse set of viewpoints. The geometry model is a mesh model that includes a set of vertices representing the object's surface. The reflectance model is SVBRDF that is parameterized via multiple channels (e.g., diffuse albedo, surface-roughness, specular albedo, and surface-normals). For each vertex of the geometry model, the reflectance model includes a value for each of the multiple channels. The object reconstruction model is employed to render graphical representations of a virtualized object (a VO based on the physical object) within a computation-based (e.g., a virtual or immersive) environment. Via the reconstruction model, the VO may be rendered from arbitrary viewpoints and under arbitrary lighting conditions.

A “Concurrent Projector-Camera” uses an image projection device in combination with one or more cameras to enable various techniques that provide visually flicker-free projection of images or video, while real-time image or video capture is occurring in that same space. The Concurrent Projector-Camera provides this projection in a manner that eliminates video feedback into the real-time image or video capture. More specifically, the Concurrent Projector-Camera dynamically synchronizes a combination of projector lighting (or light-control points) on-state temporal compression in combination with on-state temporal shifting during each image frame projection to open a “capture time slot” for image capture during which no image is being projected. This capture time slot represents a tradeoff between image capture time and decreased brightness of the projected image. Examples of image projection devices include LED-LCD based projection devices, DLP-based projection devices using LED or laser illumination in combination with micromirror arrays, etc.

High dynamic range depth generation is described for 3D imaging systems. One example includes receiving a first exposure of a scene having a first exposure level, determining a first depth map for the first depth exposure, receiving a second exposure of the scene having a second exposure level, determining a second depth map for the second depth exposure, and combining the first and second depth map to generate a combined depth map of the scene.

Apparatuses, systems and methods for modulating returned light for acquisition of 3D data from a scene are described. A 3D imaging system includes a Fabry-Perot cavity having a first partially-reflective surface for receiving incident light and a second partially-reflective surface from which light exits. An electro-optic material is located within the Fabry-Perot cavity between the first and second partially-reflective surfaces. Transparent longitudinal electrodes or transverse electrodes produce an electric field within the electro-optic material. A voltage driver is configured to modulate, as a function of time, the electric field within the electro-optic material so that the incident light passing through the electro-optic material is modulated according to a modulation waveform. A light sensor receives modulated light that exits the second partially-reflective surface of the Fabry-Perot cavity and converts the light into electronic signals. Three-dimensional (3D) information regarding a scene-of-interest may be obtained from the electronic signals.
