Patent number: 11989893Abstract: Systems and methods are provided for generating alignment parameters for processing data associated with a vehicle. In one embodiment, a method includes: receiving image data associated with an environment of the vehicle; receiving lidar data associated with the environment of the vehicle; processing, by a processor, the image data to determine data points associated with at least one pole identified within image data; processing, by the processor, the lidar data to determine data points associated with at least one pole identified within the lidar data; selectively storing the data points as data point pairs in a data buffer; iteratively processing, by the processor, the data point pairs with a plurality of perturbations to determine a transformation matrix; generating, by the processor, alignment data based on the transformation matrix; and processing future data based on the alignment parameters.Type: GrantFiled: March 22, 2022Date of Patent: May 21, 2024Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Yousef Omar, Wende Zhang, Hao Yu

Patent number: 11892574Abstract: Systems and method are provided for controlling a vehicle. In one embodiment, a method includes: receiving, by a controller onboard the vehicle, lidar data from the lidar device; receiving, by the controller, image data from the camera device; computing, by the controller, an edge map based on the lidar data; computing, by the controller, an inverse distance transformation (IDT) edge map based on the image data; aligning, by the controller, points of the IDT edge map with points of the lidar edge map to determine extrinsic parameters; storing, by the controller, extrinsic parameters as calibrations in a data storage device; and controlling, by the controller, the vehicle based on the stored calibrations.Type: GrantFiled: July 31, 2020Date of Patent: February 6, 2024Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Yousef A.

Patent number: 11348282Abstract: A camera of a vehicle has a field of view. A perception module of the vehicle is configured to determine a location of an object relative to the vehicle based on a model for the camera and a camera ground truth orientation of the camera. A calibration module is configured to: wirelessly receive images from the camera; determine a vehicle camera target based on the images; when the vehicle camera target is aligned with a calibration module target on the calibration module, determine a present orientation of the calibration module measured using a gyroscope of the calibration module; when at least one component of the present orientation of the calibration module is different than the at least one component of an expected orientation of the calibration module, determine an updated camera ground truth orientation of the camera; and wirelessly transmit the updated ground truth orientation to the vehicle.Type: GrantFiled: February 4, 2021Date of Patent: May 31, 2022Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Andrew W. Averhart, Ismail Hamieh, Mohsen Khalili, Yousef A. Omar
