Development of 3D endoscope for minimum invasive surgical system

One of the interesting surgery visualization that has helped the surgeon is in the field of endoscope. Endoscopic surgery is rapidly spreading in various areas since it is less invasive than conventional open surgery. Further, it helps the surgeon to have the internal view of the human body to identify and localize the damaged area. The recent and upgraded 3D endoscope enables the surgeon with depth perception and stereo vision. Stereo vision adaptability plays an important role in depth perception and is usually present in human beings and animals in predator's category. The estimation of depth provides an approximation of the distance of various objects in the scene from the miniature cameras. The paper presents an approach for generating an anaglyph view of the scene using two images generated by a stereo sensor. The algorithm runs in real time to generate a stereo video using two video streams from the sensors. The processed output is in 3D, which helps surgeon in estimating the depth of the internal organs.
