| Zusammenfassung: | The present invention relates to a non-contact calibration method and an optical device, where the device consists of a calibration light source module mounted on an image capturing lens of endoscope. The light source module projects a calibration light of normal type geometric pattern onto an inspected area when the projected calibration light is orthogonal to the inspected area. On the other hand, a distortion type of the geometric pattern is occurred when the when the projected calibration light is not orthogonal to the inspected area. Accordingly, a normal type pattern is obtained by adjusting the setting angle of the image capturing lens. |
