METHOD AND APPARATUS WITH CALIBRATION

A processor-implemented method with calibration includes: detecting a pre-known pattern comprised in a surface of a road from a driving image captured by a camera of a vehicle; transforming image coordinates in an image domain of the pattern into world coordinates in a world domain; determining whet...

description A processor-implemented method with calibration includes: detecting a pre-known pattern comprised in a surface of a road from a driving image captured by a camera of a vehicle; transforming image coordinates in an image domain of the pattern into world coordinates in a world domain; determining whether to calibrate the camera capturing the driving image by comparing a size predicted based on the world coordinates of the pattern and a reference size of the pattern; in response to a determination to calibrate the camera, determining relative world coordinates of the pattern with respect to a motion of the camera, using images captured by the camera at different time points; transforming the relative world coordinates of the pattern into absolute world coordinates of the pattern; and calibrating the camera using a corresponding relationship between the absolute world coordinates of the pattern and the image coordinates of the pattern.
