Patent number: 11900814Abstract: An autonomous vehicle is described herein. The autonomous vehicle comprises a first sensor and a second sensor having limited fields of view, an articulation system, and a computing system. The computing system determines a first region and a second region external to the autonomous vehicle based on a sensor prioritization scheme comprising a ranking of regions surrounding the autonomous vehicle. The computing system then causes the articulation system to orient the first sensor towards the first region and the second region towards the second region. Responsive to receiving a sensor signal from the first sensor indicating that an object has entered a field of view of the first sensor, the computing system determines a third region having a higher ranking than the second region within the sensor prioritization scheme. The computing system then causes the articulation system to orient the second sensor towards the third region.Type: GrantFiled: May 30, 2022Date of Patent: February 13, 2024Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Elliot Branson, Eric Lujan, Benjamin Earle Weinstein-Raun

Patent number: 11776215Abstract: One embodiment provides techniques for automatically pre-labeling point cloud data with cuboid annotations. Point cloud data is processed using ML models to detect, associate, and localize objects therein, in order to generate cuboid tracks that each include a series of cuboid annotations associated with an object. An object detection model that detects objects and performs coarse localization is trained using a loss function that separately evaluates the distances between corners of predicted cuboids and corners of ground truth cuboids for position, size, and yaw. A refinement model that performs more accurate localization takes as input 2D projections of regions surrounding cuboid tracks predicted by the object detection model and the cuboid tracks, and outputs refined cuboid tracks. The refined cuboid tracks are filtered to a set of keyframes, with in-between frames being interpolated. The cuboid tracks can then be presented to a user for viewing and editing.Type: GrantFiled: December 16, 2019Date of Patent: October 3, 2023Assignee: SCALE AI, INC.Inventors: Chiao-Lun Cheng, Elliot Branson, Leigh Marie Braswell, Daniel Havíř, Jeffrey Alan Anders
