Title: CALIBRATION METHOD AND DEVICE
Abstract:
A calibration method used in a calibration device that converts around-vehicle images captured by a plurality of cameras into overhead images for synthesis, wherein one calibration index in which at least two parallel straight lines are drawn is installed in a common imaging area of two of the cameras, and at least three units of the calibration index installed on a flat surface around a vehicle are used to perform calibration. Therefore, the time and effort necessary for calibration such as the creation, transportation, and laying of a calibration chart are reduced, and high-precision camera calibration including the calibration of internal distortion and external parameters is performed.
