摘要： An optical calibration system is configured to determine camera calibration information of a virtual reality camera. The optical calibration system comprises a light source, a first and a second planar grid, and an optical calibration controller. The light source is configured to backlight the first and the second planar grids. Each planar grid includes a plurality of fiducial markers that are backlit by the light source. The optical calibration controller determines camera calibration information of a virtual reality camera selecting and analyzing a plurality of captured images that include a portion of the first or the second planar grid with fiducial markers backlit.

摘要： A virtual reality (VR) headset includes a first camera and a second camera capturing image data of an environment of the VR headset. Each camera has a field of view, and a portion of the fields of view of the first and second cameras overlap while a portion of the fields of view do not overlap. A processor receiving the image data from the first and second cameras is configured to identify a first observation of a position of the VR headset in the environment and positions of a plurality of features based on the image data captured by the first camera. The processor also identifies a second observation of the position of the VR headset in the environment and the positions of the features based on the image data captured by the second camera. Based on the first and second observations, the processor determines a model of the environment.

摘要： The disclosed computer-implemented method for offloading image-based tracking operations from a general processing unit to a hardware accelerator unit may include (1) sending imaging data from an imaging device to a hardware accelerator unit, and (2) directing the hardware accelerator unit to generate a multi-scale representation of the imaging data sent from the imaging device, (3) preparing a set of input data for a set of image-based tracking operations, and (4) directing the hardware accelerator unit to execute the set of image-based tracking operations using the generated multi-scale representation of the imaging data and the prepared set of input data. Various other methods, systems, and computer-readable media are also disclosed.

摘要： Embodiments of the present disclosure support a head-mounted display (HMD) wirelessly coupled to a console. The HMD includes a positional tracking system, a beam controller and a transceiver. The positional tracking system tracks position of the HMD and generates positional information describing the tracked position of the HMD. The transceiver communicates with a console via a wireless channel, in accordance with communication instructions, the communication instructions causing the transceiver to communicate over one directional beam of a plurality of directional beams. The beam controller determines a change in the positional information. Based on the change to the positional information, the beam controller determines a directional beam of the plurality of directional beams. The beam controller further generates the communication instructions identifying the determined directional beam, and provides the communication instructions to the transceiver.

摘要： A virtual reality (VR) system tracks the position of a controller. The VR system includes an image tracking system comprising of a number of fixed cameras, and a headset worn by the user that includes an imaging device to capture images of a controller operated by the user. The controller includes a set of features disposed on the surface of the controller. The image tracking system provides a first view of the controller. The imaging device mounted on the headset provides a second view of the controller. Each view of the controller (i.e., from the headset and from the image tracking system) provides a distinct set of features observed on the controller. The first and second sets of features are identified from the captured images and a pose of the controller is determined using the first set of features and the second set of features.
