Patent number: 11982773Abstract: Various aspects of the subject technology relate to a lidar validation system. The lidar validation system is configured to acquire one or more lidar point clouds from a lidar unit, wherein the lidar unit comprises one or more lasers, and wherein each point cloud is a representation of a scene according to a laser in the lidar unit, the scene comprising a fiducial target. The lidar validation system is configured to generate, based on points in the one or more point clouds, a target cloud that correspond to the fiducial target, perform a rigid body processing to minimize a sum of distances from each point in the target cloud to the fiducial target, and generate lidar validation measurements based on the distances from each point in the target cloud to the fiducial target.Type: GrantFiled: February 16, 2023Date of Patent: May 14, 2024Assignee: GM Cruise Holdings LLCInventors: Ankit Rohatgi, Peter Megson, Mariana Rihl, Adam Cadien, Robert Vets

Publication number: 20230154047Abstract: Sensors coupled to a vehicle are calibrated, optionally using a dynamic scene with sensor targets around a motorized turntable that rotates the vehicle to different orientations. One vehicle sensor captures a representation of one feature of a sensor target, while another vehicle sensor captures a representation of a different feature of the sensor target, the two features of the sensor target having known relative positioning on the target. The vehicle generates a transformation that maps the captured representations of the two features to positions around the vehicle based on the known relative positioning of the two features on the target.Type: ApplicationFiled: January 5, 2023Publication date: May 18, 2023Inventors: Adam Cadien, Zhonghua Ma, Jabeer Ahmed, Nicholas Semansky

Patent number: 11641461Abstract: Sensors coupled to a vehicle are calibrated using a dynamic scene with sensor targets around a motorized turntable that rotates the vehicle to different orientations. The sensors capture data at each orientation along the rotation. The vehicle's computer identifies representations of the sensor targets within the data captured by the sensors, and calibrates the sensor based on these representations. The motorized turntable may confirm that rotation has stopped to the vehicle to trigger sensor capture, and the vehicle may communicate completion of sensor capture at an orientation to the motorized turntable to trigger further rotation.Type: GrantFiled: October 29, 2021Date of Patent: May 2, 2023Assignee: GM Cruise Holdings LLC.Inventors: Ankit Rohatgi, Adam Cadien, Jun-Wei Hew, Nick Semansky, Zhi Yuan Sherwin Lau, Zhichang Yan, Haven Lau

Patent number: 11166010Abstract: Sensors coupled to a vehicle are calibrated using a dynamic scene with sensor targets around a motorized turntable that rotates the vehicle to different orientations. The sensors capture data at each vehicle orientation along the rotation. The vehicle's computer identifies representations of the sensor targets within the data captured by the sensors, and calibrates the sensor based on these representations, for example by comparing these representations to previously stored information about the sensor targets and generating a correction based on differences, the correction applied to post-calibration sensor data.Type: GrantFiled: September 16, 2020Date of Patent: November 2, 2021Assignee: GM Cruise Holdings, LLCInventors: Daniel Lee, Ankit Rohatgi, Adam Cadien

Patent number: 11146783Abstract: Systems and methods provide for adaptive real-time streaming of Autonomous Vehicle (AV) data. In some embodiments, the AV can receive a request from the remote computing system for real-time streaming of a first type of AV data and adaptively streaming a second type of AV data when one or more streaming conditions are satisfied. The first type of AV data and the second type of AV data can be captured as raw data by sensors, actuators, transducers, and other components of the AV. The AV can stream the first type of AV data to the remote computing system in real-time for a first time period. When the AV determines the streaming conditions are satisfied, the AV can automatically determine the second type of AV data to stream to the remote computing system in real-time for a second time period.Type: GrantFiled: August 16, 2019Date of Patent: October 12, 2021Assignee: GM Cruise Holdings, LLCInventors: Zhizhong Yan, Adam Cadien
