An optical tracking system comprises a marker part, an imaging part, and a processing part. The marker part includes a pattern having particular information and a first lens. First and second imaging parts respectively include second and third lenses and first and second imaging units. The processing part determines a posture of the marker part from a first coordinate conversion equation between a coordinate on a pattern surface of the pattern and a first pixel coordinate on a first image of the pattern, and a second conversion equation between the coordinate on the pattern surface of the pattern and a second pixel coordinate on a second image of the pattern, which include a rotation conversion between the first pixel coordinate and the second pixel coordinate on the second image of the pattern, and tracks the marker part by using the determined posture of the marker part. Accordingly, the marker part can be precisely tracked in a simpler and easier method. |
