Publication number: 20240133681Abstract: A device for calibrating a laser level includes a base platform, a target, and an image recognition device. The base platform is configured to support the laser level that is to be mounted on the base platform at a first position. The target is arranged at a second position of the base platform and configured to receive a laser. The image recognition device is configured to obtain images of lasers projected on the target before and after the laser level rotates a first angle, determine, based on an image recognition result of the images, positions of the lasers emitted by the laser level to determine a deviation distance, and determine whether the laser level needs to be calibrated based on the deviation distance. The deviation distance is determined by position data of the first position and the second position, and the first angle.Type: ApplicationFiled: December 6, 2023Publication date: April 25, 2024Inventors: Xin SHI, David XING

Patent number: 11926346Abstract: In various examples, a yield scenario may be identified for a first vehicle. A wait element is received that encodes a first path for the first vehicle to traverse a yield area and a second path for a second vehicle to traverse the yield area. The first path is employed to determine a first trajectory in the yield area for the first vehicle based at least on a first location of the first vehicle at a time and the second path is employed to determine a second trajectory in the yield area for the second vehicle based at least on a second location of the second vehicle at the time. To operate the first vehicle in accordance with a wait state, it may be determined whether there is a conflict between the first trajectory and the second trajectory, where the wait state defines a yielding behavior for the first vehicle.Type: GrantFiled: August 5, 2021Date of Patent: March 12, 2024Assignee: NVIDIA CorporationInventors: Fangkai Yang, David Nister, Yizhou Wang, Rotem Aviv, Julia Ng, Birgit Henke, Hon Leung Lee, Yunfei Shi
