Methods, apparatus, devices, and systems for three-dimensional (3D) displaying objects are provided. In one aspect, a method includes obtaining data including respective primitive data for primitives corresponding to an object, determining an electromagnetic (EM) field contribution to each element of a display for each of the primitives by calculating an EM field propagation from the primitive to the element, generating a sum of the EM field contributions from the primitives for each of the elements, transmitting to each of the elements a respective control signal for modulating at least one property of the element based on the sum of the EM field contributions, and transmitting a timing control signal to an illuminator to activate the illuminator to illuminate light on the display, such that the light is caused by the modulated elements of the display to form a volumetric light field corresponding to the object.

Three-dimensional displays using electromagnetic field computations

A system and method for measuring depth using an optical radar system are described. The system includes an optical radar, a camera, a display, and a processor. The optical radar emits a signal towards an object. The processor identifies an object depicted in an image captured with the camera. The processor generates the signal with a non-repeating pattern of amplitude and frequency, and computes a depth of the object based on a difference in phase angle between the signal emitted from the optical radar and a return signal received at the optical radar. The depth includes a distance between the optical radar and the object. The processor generates AR content based on the identified object and adjusts a characteristic of the AR content in the display based on the computed depth of the object.

Light-based radar system for augmented reality

During calibration, a wearable video headset displays a pattern on a partially transparent display positioned in a field of view of a user's eye. The user has a hand-held marker that includes a scaled version of the displayed pattern. The user moves the marker toward or away from the user's eye until the pattern on the marker appears to be the same size as the pattern on the display. When the sizes match, the headset measures a distance between a forward-facing camera and the hand-held marker. The headset uses the measured distance, and geometrical relationships, to determine the spacing between the user's eye and the display. Such calibration can ensure that the images displayed to the user mesh realistically with the surroundings, which remain partially visible through the partially transparent display of the video headset.

Wearable video headset and method for calibration

A system and method for sampling-based color extraction for augmented reality are described. A viewing device includes an optical sensor to capture an image of a real-world object. A color extraction software divides the captured image into multiple regions or recognizes pre-defined regions and identifies a color value for each region. A color-based augmented reality effect module retrieves a virtual content based on the color values for the regions, and delivers the virtual content in the viewing device.

Sample based color extraction for augmented reality

A system and method for real-time texture mapping for an augmented reality system are described. A viewing device includes an optical sensor to capture an image of a real-world object. A texture extraction module extracts a texture of the image of the real-world object. A recognition module identifies the real-world object based on the captured image. A texture mapping module retrieves a virtual object corresponding to the identified real-world object, maps the texture to the virtual object, dynamically updates the texture to the virtual object in real time, and generates a visualization of the virtual object in a display of the viewing device.

Real time texture mapping for augmented reality system

An augmented reality (AR) device comprises a transparent display, a thermal sensor, a depth sensor, and a processor. The thermal sensor generates thermal data related to physical objects detected by the AR device. A thermal baseline identification engine forms a thermal baseline using data from infrared imaging and depth profiling sensors, thermal data of the physical objects in a mapped 3D space, thermal context of the objects both spatially and based on their operating status, and their thermal parameters. A thermal anomaly identification engine identifies a thermal anomaly based on the established thermal baseline and the real time measurements, and generates a warning notification in response to the identified thermal anomaly.
