Abstract: Systems and methods 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 vehicle identified within image data; processing, by the processor, the lidar data to determine data points associated with at least one vehicle identified within the lidar data; selectively storing the data points in a data buffer based on at least one condition associated with a quality of the data points; processing, by the processor, the data points in the data buffer with a joint analysis method to generate alignment parameters between the lidar and the camera; and processing future data based on the alignment parameters.

Abstract: 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.
