Patent number: 11769258Abstract: Systems and techniques are described herein for processing images. The systems and techniques can be implemented by various types of systems, such as by an extended reality (XR) system or device. In some cases, a first processor receives an image of an environment captured by an image sensor, identifies features depicted in the image, and generates descriptors for the features. The first processor sends the descriptors to a second processor, which may be more powerful than the first processor. The second processor receives the descriptors. The second processor associates the plurality of features with a map of the environment based on at least a subset of the plurality of descriptors. For example, the second processor can track at least a subset of the features based on at least a subset of the descriptors and based on feature information from one or more additional images of the environment.Type: GrantFiled: February 3, 2021Date of Patent: September 26, 2023Assignee: QUALCOMM IncorporatedInventors: Ajit Deepak Gupte, Gerhard Reitmayr, Abhijeet Bisain, Pushkar Gorur Sheshagiri, Chayan Sharma, Ajit Venkat Rao

Patent number: 11144117Abstract: Methods, systems, and devices for deep learning based head motion prediction for extended reality are described. The head pose prediction may involve training one or more layers of a machine learning network based on application data and an estimated head motion range associated with the extended reality system. The network may receive one or more bias corrected inertial measurement unit (IMU) measurements based on a sensor. The network may model a relative head pose of the user as a polynomial of time over a prediction interval based on the bias corrected IMU measurements and the trained one or more layers of the machine learning network. The network may determine a future relative head pose of the user based on the polynomial (e.g., which may be used for virtual object generation, display, etc. within an extended reality system).Type: GrantFiled: May 18, 2020Date of Patent: October 12, 2021Assignee: QUALCOMM IncorporatedInventors: Chiranjib Choudhuri, Ajit Deepak Gupte, Pushkar Gorur Sheshagiri, Gerhard Reitmayr, Tom Edward Botterill
