Development Of The Dual-eye Imaging Techniques For The Stereo Display Of Endoscopes

Electro-endoscopes technique is an important method to acquire medical image. Electro-endoscopes has become mature medical equipment though long periods of clinic application and continues improvement, it has been wildly used in the image acquirement of lumen and treatment. It can show the lumen image in focus.With the development of stereographic techniques in medical image, people are eager to get the 3D medical image with which we can get over the shortage of medical endoscopes. Then, a new technique called virtual endoscopes appears. As a kind of diagnose method without damage, VE is reconstructed from the data of CT or MRI. It can simulate the stranded electro-endoscopes.Unfortunately, VE is still been researched recently and has some shortage that cannot be solved by itself. VE cannot replace the Electro-endoscopes. Our task is how to keep the merit and realize stereographic display. We use the virtual reality techniques and the computer stereo display techniques to develop a dual-eye stereographic display system used in electro-endoscopes. We have designed the front part of endoscopes and the video system with new methods. Using the crystal glasses, doctors can see the stereographic image of endoscopes.In this article, the model of human dual-eye and the Binocular Parallax theory are analyzed and a dual-camera model has been put forward. Subsequently, an experiment will be made to stimulate the project in which the endoscopes image will be acquired and the stereo display can be created. This article will give new idea to improve the electro-endoscopes techniques and the application of stereo display methods in medical image processing.
