Abstract
A calibration method for a three-dimensional (3D) augmented reality and an apparatus thereof are provided. The calibration method includes determining a first conversion parameter representing a relationship between a coordinate system of an eye-tracking camera and a coordinate system of a calibration camera by capturing a physical pattern using the eye-tracking camera and the calibration camera, and determining a second conversion parameter representing a relationship between a coordinate system of a virtual screen and the coordinate system of the calibration camera and a size parameter representing a size of the virtual screen by capturing a virtual pattern displayed on the virtual screen using the calibration camera.
