OPTICAL TRACKING SYSTEM AND TRACKING METHOD USING THE SAME

摘要

An optical tracking system and a method using the same capable of detecting an exact spatial position and a direction of a target regardless of the distance from the target to be calculated is disclosed. The optical tracking system and a method using the same according to an embodiment of the present invention has an effect of expanding an available area by detecting an exact spatial position and a direction of a target regardless of the distance from the target to be calculated, as well as, a system downsizing is also achieved by significantly reducing size of the marker unit compared with conventional system.

主权项

1. An optical tracking system comprising:
at least one marker unit attached on a target, and emitting a parallel light to form an enlarged image of a pattern portion which is included inside the marker unit; at least one image forming unit receiving the parallel light of the pattern portion emitted from the marker unit and forming the enlarged image of the pattern portion; and a processor calculating a spatial position and a direction of the marker unit by using the enlarged image of the pattern portion formed on the image forming unit.
