Abstract: Imaging systems and techniques are described. A system receives an image of an environment captured using an image sensor according to an image capture setting, and receives motion data captured using a motion sensor. The system determines a weight associated with at least one of a plurality of features of the environment in the image based on an estimated motion blur level for the at least one of the features of the environment in the image. The estimated motion blur level is based on the motion data and the image capture setting. The system tracks the features of the environment across a plurality of images (that includes the received image) according to respective weights (that include the determined weight) for the features of the environment across the plurality of images. The system can use the tracked features for mapping the environment and/or determining the pose of the system.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to capture images with subjects at different depths. A method of processing image data includes obtaining, at an imaging device, a first image of an environment from an image sensor of the imaging device; determining a region of interest of the first image based on features depicted in the first image, wherein the features are associated with the environment; determining a representative luma value associated with the first image based on image data in the region of interest of the first image; determining one or more exposure control parameters based on the representative luma value; and obtaining, at the imaging device, a second image captured based on the one or more exposure control parameters.

Abstract: Systems and techniques are described herein for processing frames. 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 process can include obtaining feature information associated with a feature in a current frame, wherein the feature information is based on one or more previous frames; determining an estimated pose of the apparatus associated with the current frame; obtaining a distance associated with the feature in the current frame; and determining an estimated scale of the feature in the current frame based on the feature information associated with the feature, the estimated pose, and the distance associated with the feature.

Abstract: Methods, devices, and apparatuses are provided to facilitate a positioning of an item of virtual content in an extended reality environment. For example, a placement position for an item of virtual content can be transmitted to one or more of a first device and a second device. The placement position can be based on correlated map data generated based on first map data obtained from the first device and second map data obtained from the second device. In some examples, the first device can transmit the placement position to the second device.

Abstract: Methods, devices, and apparatuses are provided to facilitate a positioning of an item of virtual content in an extended reality environment. For example, a first user may access the extended reality environment through a display of a mobile device, and in some examples, the methods may determine positions and orientations of the first user and a second user within the extended reality environment. The methods may also determine a position for placement of the item of virtual content in the extended reality environment based on the determined positions and orientations of the first user and the second user, and perform operations that insert the item of virtual content into the extended reality environment at the determined placement position.

Abstract: Systems and techniques are described herein for using head mounted display (HMD) hinge motion to calibrate the head mounted device. For example, an device (or component of the device) can obtain, via one or more sensors, sensor measurements during rotation of a display of the HMD between a first end of a range of motion of a hinge of the display about an axis and a second end of the range of motion of the hinge about the axis; determine parameters of the HMD based on the sensor measurements and the rotation of the display between the first end of the range of motion of the hinge and the second end of the range of motion of the hinge about the axis; and determine pose information for the HMD based on the determined parameters.

Abstract: 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.
