Abstract
A space registration system includes a display apparatus, an image sensor, a processor, and a plane mirror. The display apparatus has an inherent display coordinate system which defines a coordinate of the virtual space. The image sensor has an inherent sensor coordinate system which defines a coordinate of the real space. The processor analogizes a transformation equation of the sensor coordinate system and the display coordinate system by means of symmetry of an incidence angle and a reflection angle of light with respect to the mirror surface, compares a coordinate of the reflection image with respect to the display coordinate system with a known coordinate of the reflection image with respect to the sensor coordinate system, and adjusts the transformation equation of the sensor coordinate system and the display coordinate system.
