Abstract
A method of calculating the coordinate data of an object includes the steps of: providing a mirror surface for generating a reflection of an object; providing an image sensor for capturing an image of the object and an image of the reflection; obtaining an individual image of the object when the image of the object and the image of the reflection overlap to form an overlapped image; and calculating the coordinate data of the object based on the overlapped image and the individual image.
