In order to verify a surgical operation image matching, a model of a target is manufactured. Then, a reference body is attached to the model. Then, three-dimensional reference data regarding to the model is obtained. Then, grid patterned light is emitted onto the model to obtain reflection image. Then, three-dimensional shape is measured from the reflection image, and measurement image is obtained from the three-dimensional shape. Then, the measurement image and previously obtained three-dimensional reference data are matched. Then, reference position of the target in the three-dimensional reference data is compared with estimated position of the target, which is estimated by the reference body in the measurement image. Therefore, the matching of the surgical operation can be verified.

Method of verifying a surgical operation image matching and method of compensating a surgical operation image matching

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 three-dimensional coordinates of each of makers using one image forming unit. In the tracking system and method using the same, lights emitted from the markers are transferred to one image forming unit through two optical paths, an image sensor of the image forming unit forms two images (direct image and reflection image) of the two optical paths of the markers, and therefore, the 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 since it is possible to calculate a spatial position and direction of the markers attached on a target by using one image forming unit.

Tracking system and tracking method using the same

A stereo microscope capable of not only adjusting the three dimensional effect of stereoscopic image but also focusing exactly even when the three dimensional effect of stereoscopic image is adjusted, is provided. A spacing distance of a pair of zoom unit can be adjusted so that a user can adjust three dimensional effect of image seen through an ocular lens according to personal tendency to improve convenience. Additionally, an object with a depth such as a hole can be exactly observed without interference of a boundary. Further, even though the three dimensional effect of an image is adjusted by adjusting the spacing distance of the pair of zoom units, the focus of optical system can be exactly adjusted.
