Abstract

A calibration system for a multi-camera system is disclosed. The calibration system includes a connection device, a storage device, and a processor. The processor is configured to control each camera of the multi-camera system to capture a calibration image of a calibration board having a pattern including multiple conventional features and at least one non-conventional feature in which an FOV of the calibration image of at least one camera does not contain at least one conventional feature of the pattern, detect the conventional features and the non-conventional feature in the calibration image and record positions thereof in the storage device, transform a position of each conventional feature into absolute coordinates relative to reference coordinates by using a position of the non-conventional feature as the reference coordinates, and according to the absolute coordinates of the transformed conventional features, match the conventional features in the calibration images captured by the cameras to calibrate the cameras.
