摘要： A method includes obtaining, from a memory of an electronic device connected to a head mounted display (HMD), a first reference frame, wherein the first reference frame comprises a first set of pixels associated with a first time. The method includes, rendering, at the electronic device, a source image as a new frame, wherein the new frame includes a second set of pixels associated with a display to be provided by the HMD at a second time, and generating, by the electronic device, a differential frame, wherein the differential frame is based on a difference operation between pixels of the new frame with pixels of the first reference frame to identify pixels unique to the new frame. Still further, the method includes sending the differential frame to the HMD, and storing the new frame in the memory of the electronic device as a second reference frame.

摘要： Generating a 3D scene reconstruction using depth fusion can include creating a high-resolution sparse depth map by mapping sensed depths from a low-resolution depth map to points corresponding to pixels of a high-resolution color image of a scene. The high-resolution sparse depth map can have the same resolution as the high-resolution color image. A fused sparse depth map can be produced by combining the high-resolution sparse depth map with sparse depths reconstructed from the high-resolution color image. The high-resolution dense depth map can be generated based on fused sparse depths of the fused sparse depth map.

摘要： A method to correct for drift in an electronic device is described. The method comprises determining a first center pose of the electronic device; tracking, using a sensor in conjunction with computer vision operating on a processor, at least one key point within a scene when the first center pose is within a tolerance with respect to a reported center pose; determining a derived center poser based upon the first center pose and the at least one key point; disabling the sensor for a predetermined time; determining, after the predetermined time, whether a second center pose is within the tolerance with respect to the derived center pose; tracking, using the sensor, the at least one key point when the second center pose is within the tolerance with respect to the derived center pose; and adjusting the second center pose when there is a difference between the second center pose and the derived center pose.

摘要： Updating an image during real-time rendering of images by a display device can include determining a depth for each pixel of a color frame received from a source device and corresponding to the image. Each pixel's depth is determined by image-guided propagation of depths of sparse points extracted from a depth map generated at the source device. With respect to pixels corresponding to an extracted sparse depth point, image-guided depth propagation can include retaining the depth of the corresponding sparse depth point unchanged from the source depth map. With respect to each pixel corresponding to a non-sparse depth point, image-guided depth propagation can include propagating to the corresponding non-sparse depth point a depth of a sparse depth point lying within a neighborhood of the non-sparse depth point. Pixel coordinates of the color frame can be transformed for generating a space-warped rendering of the image.

摘要： A method for tracking a position of a device is provided, wherein the method includes capturing, by using a first positional resolution, based on information from a first sensor, a first position of the device within an optical tracking zone of the first sensor. The method also includes determining, based on information from the first sensor, that the device exits the optical tracking zone of the first sensor. Further, the method includes responsive to determining that the device exits the optical tracking zone of the first sensor, capturing, at a second positional resolution, a second position of the device based on acceleration information from a second sensor, wherein the second positional resolution corresponds to a minimum threshold value for the acceleration information from the second sensor.

摘要： A method to correct for a vehicle induced change of direction in an electronic device is described. The method comprises determining a first center pose of the electronic device, and determining when a motion of the electronic device is caused by a vehicle. At least one key point within a scene can be tracked, using a sensor in conjunction with computer vision operating on a processor, to determine a second center pose. It is then determined whether the second center pose is within a tolerance with respect to the first center pose; and the second center pose is adjusted when there is a difference between the second center pose and the first center pose.

摘要： A method includes obtaining, from an image sensor, image data of a real-world scene; obtaining, from a depth sensor, sparse depth data of the real-world scene; and passing the image data to a first neural network to obtain one or more object regions of interest (ROIs) and one or more feature map ROIs. Each object ROI includes at least one detected object. The method also includes passing the image data and sparse depth data to a second neural network to obtain one or more dense depth map ROIs; aligning the one or more object ROIs, one or more feature map ROIs, and one or more dense depth map ROIs; and passing the aligned ROIs to a fully convolutional network to obtain a segmentation of the real-world scene. The segmentation contains one or more pixelwise predictions of one or more objects in the real-world scene.

摘要： A method implemented by an extended reality (XR) display device includes rendering a current image frame received from an external electronic device associated with the XR display device. The current image frame is associated with a current pose of the XR display device. The method further includes receiving an updated image frame from the external electronic device, calculating an updated pose based on one or more characteristics of the updated image frame, and determining whether the updated pose is within a pose range with respect to the current pose. The method thus further includes re-rendering, on one or more displays of the XR display device, a current image frame based on whether the updated pose is determined to be within the pose range.
