Embodiment Construction

[0013] The detailed description provided below in connection with the accompanying drawings is intended as a description of the present example and is not intended to represent the only forms in which the present example may be constructed or utilized. The description sets forth the functionality of the example and the sequence of steps used to construct and operate the example. However, the same or equivalent functions and sequences can be performed by different examples.

[0014] An improved tracker for tracking the 3D position of objects from captured sensor data, such as images, is described. In some examples, the tracker is also configured to compute shape parameters of the object, but this is not required. A tracker has a feedback engine that computes and outputs feedback about the performance of the tracker. For example, tracker performance typically degrades when a tracked object is close to another object that is difficult to segment from the tracked object. For ex...

Abstract

A computing device has an input configured to receive data captured by at least one capture device, wherein the data depicts at least a portion of an object moving in an environment. The computing device has a tracker configured to track a real-world position and orientation of an object using the captured data. A processor at the computing device is configured to calculate and output feedback regarding performance of the tracker, wherein the feedback prompts the user to adjust movement of the object for improved tracking of the object by the tracker.

Description

Background technique [0001] Tracking an object in three dimensions (3D) involves computing the object's global position and orientation based on captured sensor data and where the object is articulated (e.g., a human body, human hand, or laptop computer), computing one or more articulated point location. There is a growing need to improve the accuracy of this tracking to better control systems that use tracking data, such as augmented reality systems, virtual reality systems, medical devices, natural user interfaces, gaming systems, and more. This can create problems in systems that use trace data where traces fail or are inaccurate. Contents of the invention [0002] A brief summary of the disclosure is presented below in order to provide the reader with a basic understanding. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Its sole p...
