1. A method of automated calibration of multimodal sensors, the method comprising:
capturing a data sample from at least one modality of the multimodal sensors;
analyzing the captured data sample for one or more circles;
on a condition that the analyzing determines a single circle, centering the single circle in the center of an image from the data sample;
on a condition that the analyzing determines more than one circle, determining a center of a centroid of a threshold image from the data sample; and
calibrating the at least one modality by comparing the centered single circle or center of the centroid with the center added from at least one other modalities of the multimodal sensors.
