Abstract: In one embodiment for generating passthrough, a computing system may access images of an environment captured by cameras of a device worn by a user. The system may generate, based on the images, depth measurements of objects in the environment. The system may generate a mesh covering a field of view of the user and then update the mesh based on the depth measurements to represent a contour of the objects in the environment. The system may determine a first viewpoint of a first eye of the user and render a first output image based on the first viewpoint and the updated mesh. The system may then display the first output image on a first display of the device, the first display being configured to be viewed by the first eye of the user.

Abstract: A coordinate system of a camera of an autonomous vehicle is calibrated to a coordinate system of a LIDAR module using the hand eye equation. However, traditional solutions to the hand eye equation are based on robust rotation about three axes. While calibrating a camera of a car, there is usually robust rotation about only one axis. Degeneracy in rotation about two axes makes the traditional hand eye equation challenging to solve. A rotation vector is defined that has a scaling value. By using the rotation vector, the hand eye equation can be solved to calibrate a pose of the camera to a pose of the LIDAR module.

Abstract: An apparatus includes a first node configured to receive the data packets from a plurality of source nodes of the data network and to selectively route some of the received data packets to a link via a port of the first node. The apparatus also includes a link-input buffer that is located in the first node and is configured to store the some of the received data packets for transmission to the link via the port. The first node is configured to power off hardware for transmitting received data packets to the link in response to a fill level of the link-input buffer being below a threshold.
