摘要:
The disclosure describes optoelectronic devices for collecting three-dimensional data without determining disparity. The approach permits significant flexibility relative to state-of-the-art approaches for collecting three-dimensional data. For example, the illuminations (e.g., patterns) generated by the disclosed devices need not exhibit the same degree of complexity or randomness of illuminations generally required by structured-light approaches. Further, the devices described in the present disclosure exhibit, in some instances, optimal resolution over a wide distance range. An optoelectronic device described herein is operable to generate an illumination comprising a plurality of high-intensity features that exhibit a distance-dependent alteration when imaged by an imager incorporated into the optoelectronic device.

A method for processing data includes receiving a depth map of a scene containing at least a humanoid head, the depth map comprising a matrix of pixels having respective pixel depth values. A digital processor extracts from the depth map a curvature map of the scene. The curvature map includes respective curvature values of at least some of the pixels in the matrix. The curvature values are processed in order to identify a face in the scene.

Systems, devices, and methods are described herein for geometrically simplifying three-dimensional (3D) video data. In one aspect, a method may include obtaining 3D data, with the 3D data including a plurality of portions associated with a default resolution priority. A higher resolution priority may be associated with one or more portions of the 3D data. Next, portions of the 3D data may be sorted according to resolution priorities associated with each portion, and geometric simplification may be performed on the sorted portions of the 3D data, beginning with portions associated with a least resolution priority and continuing with portions associated with successively higher resolution priorities. The simplified 3D data may be processed, for example, for rendering on a computing device or transmission to another device for display or generation, such as a 3D printing device for generating a 3D object.
摘要:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Abtasten von Oberflächen mit einer Stereokamera, mit zumindest zwei Kameramodulen, welche jeweils ein Objektiv und einen Bildsensor aufweisen. Die Kameramodule sind derart angeordnet, dass sie von einem gemeinsamen Bereich einer abzutastenden Oberfläche jeweils ein Bild erfassen. Von den zumindest zwei Bildern werden die Disparitäten bestimmt. Diese zumindest zwei Bilder werden unter Berücksichtigung der Disparitäten registriert und das derart registrierte Bildpaar wird ausgewertet, Durch die Registrierung der Bildpaare anhand der Disparitäten beschreiben die Intensitätswerte korrespondierender Bildpunkte in den zumindest zwei Bildern den gleichen physikalischen Punkt an der abzutastenden Oberfläche. Hierdurch ist es möglich, die Intensitätswerte der mehreren Bilder in Kombination auszuwerten, um die abzutastende Oberfläche zu analysieren.

Apparatus and methods for focal length adjustment and depth map determination are provided for making and using the same. The focal length adjustment apparatus comprises a distance assembly configured to determine a distance between an object of interest and an imaging mechanism for imaging the object of interest. The focal length adjustment apparatus likewise can include a focal length assembly configured to automatically adjust a focal length of the imaging mechanism according to the determined distance. The focal length adjustment apparatus advantageously achieves automatic focal length adjustment with lower cost compared with solutions using laser cameras.

Methods and apparatus for using selective resolution reduction on images to be transmitted and/or used by a playback device are described. Prior to transmission one or more images of an environment are captured. Based on image content, motion detection and/or user input a resolution reduction operation is selected and performed. The reduced resolution image is communicated to a playback device along with information indicating a UV map corresponding to the selected resolution allocation that should be used by the playback device for rendering the communicated image. By changing the resolution allocation used and which UV map is used by the playback device different resolution allocations can be made with respect to different portions of the environment while allowing the number of pixels in transmitted images to remain constant. The playback device renders the individual images with the UV map corresponding to the resolution allocation used to generate the individual images.

System integrating content in real-time into dynamic 3D scene includes external server including CMS, a device including content integrating engine to process in real-time 3D scenes, and display device to display combined 3D scene output. CMS searches for social media posts on social media servers. Social media posts includes message and URL to media content. Content integrating engine includes content retriever, content queue, 3D scene component processors to process each 3D scene's visual components, scene manager and combiner. Content retriever establishes direct connection to external server, and retrieves URLs from server storage and stores URLs in content queue. Scene manager, at time of low intensity during 3D scene, signals to content retriever to retrieve media content corresponding to URLs in content queue, one scene component processor to process display setting change, or another scene component processor to process media content. Combiner to generate combined 3D scene output. Other embodiments are described.
