| Minimally Invasive Surgery (MIS), the new technology in medical treatment which is characterized by using endoscopes in surgery, is booming only in recent years. Compared with traditional surgery, it has much excellent superiority. In it the endoscopes are the key part, the ability of endoscopes will play an important role in the successfully proceeding of surgery.The paper described briefly the common history and the current stage of its development, sampled the wide application in medical. The paper also introduced in brief the fundamental principle of the Stereo vision and several prevailing technologies in display of stereo vision. The research content of the paper included: (1) the design of optical system organization for double CCD electric endoscope; (2) the system of image collecting and processing for study.The targets that the endoscope attained are: field angle: 70°, aspect angle: 0°, external diameter: Φ10mm, active length: 300mm, stereoscopic space: 150mm, system resolution: > 8.31pl/mm, image signal field frequency: 100Hz. |
