TRACKING SYSTEM AND TRACKING METHOD USING THE SAME

摘要

A tracking system and method using the same is disclosed which is capable of minimizing a restriction of surgical space by achieving a lightweight of the system as well as a reduction of a manufacturing cost through calculating a 3-dimensional coordinates of each of makers using single image forming unit. In the tracking system and method using the same has an effect of reducing a manufacturing cost of the tracking system with small and lightweight, and relatively low restriction of surgical space comparing with conventional tracking system by calculating a spatial position and a direction of the markers attached on a target by using one image forming unit through a trigonometry since a pair of maker images are formed on an image forming unit for each marker by a pair of light sources positioned different to each other.

主权项

1. A tracking system comprising:
at least three markers attached on a target to reflect lights; a pair of light sources positioned at different position to emit lights toward the markers; a lens portion passing the lights which are emitted from the pair of the light sources and reflected by the markers; an image forming unit to form a pair of marker images for each marker by receiving the lights passed by the lens portion; and a processor calculating three-dimensional coordinates of the markers by using the pair of marker images formed on the image forming unit for each marker, and calculating spatial position information and direction information of the target by comparing the three-dimensional coordinates of the markers and pre-stored geometric information between the markers adjacent to each other.
