Problems solved by technology

This prior gesture detection step limits the natural behavior of the user and complicates the gesture recognition process, as it requires the user to perform a predefined gesture prior to each interaction with the gesture recognition system

[0027] overview

[0028] 3D depth mapping of voxels (such as scenes or scenes) is used in various systems (e.g., skeletal modeling, gesture recognition systems, VR (virtual reality), augmented reality, or telecontrol sensing applications) to extract Object. For example, depth mapping is used to extract a user's hand or a user's face from voxels. Data from the three-dimensional depth map allows segmentation of the user's hand, the user's face, or another object from the background scene in the volume. Conventional methods compute 3D depth maps of complete voxels to allow segmentation of objects from voxels. However, generating a 3D depth map of complete voxels involves significant computational resources and often uses dedicated processing units. In addition, extracting high-resolution 3D depth maps that allow extraction of certain objects (eg, fingers) from background scenery may be limited by ambient light conditions that limit the efficient extraction of certain objects...

Abstract

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 captureslight 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 issegmented from the volume.

Description

technical field [0001] In some embodiments of the invention, the invention relates to object recognition, and more particularly, but not exclusively, to systems and methods using optical projection onto a scene, for example to detect and track objects such as a user's hand in three dimensions (3D). Object. Background technique [0002] Various methods allow users to remotely control certain devices. For example, predefined gestures or gestures of a user's body parts (eg, arms, legs) may control the device. In the method of using gestures or gestures for device control, when a user's body part is aligned with a designated position, the gesture is recognized, and a computer or other device performs a function or performs an action corresponding to the recognized gesture. [0003] In some implementations, the user's gesture is recognized by capturing an image or video of the user via an image capture device and analyzing a plurality of pixels in the image or video data. Conv...
