Abstract

A method of wheel encoder-to-camera calibration includes: receiving a LiDAR (Light Detection and Ranging) signal; receiving a camera signal; receiving a wheel encoder signal; calibrating a camera signal to a LiDAR signal; calibrating a wheel encoder signal to a LiDAR signal; and calibrating the camera signal to the wheel encoder signal based on the calibration of the camera signal to the LiDAR signal and the calibration of the wheel encoder signal to the LiDAR signal.

Description

technical field [0001] The present disclosure relates to wheel encoder to camera calibration, and more particularly to LiDAR (Light Detection and Ranging) assisted wheel encoder to camera calibration. Background technique [0002] Current methods for calibrating wheel encoders to cameras are either cumbersome or lack robust estimates to account for hand-eye alignment. Contents of the invention [0003] An example method of wheel encoder to camera calibration includes: receiving a LiDAR (Light Detection and Ranging, light detection and ranging) signal; receiving a camera signal; receiving a wheel encoder signal; calibrating the camera signal to the LiDAR signal; Calibrating the camera signal to the LiDAR signal; and calibrating the camera signal to the wheel encoder signal based on the calibration of the camera signal to the LiDAR signal and the wheel encoder signal to the LiDAR signal. [0004] Another example method of a wheel encoder to camera calibration includes: rece...
