Embodiment Construction

[0032] A preferred example of the present invention is described as follows in conjunction with accompanying drawing:

[0033] See figure 1 , the endoscope visual navigation system, including an image acquisition controller 2, a personal computer 1, an automatic intervention mechanism 7, an endoscope 6 and a lens deflection mechanism 5. The acquisition image controller 2 collects the internal image of the field from the CCD of the head of the endoscope 6, and transmits the image to the personal computer 1; the personal computer 1 is equipped with a visual navigation algorithm and software for displaying the state of the endoscope, and the software adopts dark The area extraction method extracts the direction of the intestinal tract in the image, and calculates the direction of the endoscopic lens head yaw according to the formula; the personal computer 1 transmits the calculated endoscopic lens head yaw direction to the lens yaw controller 3, The controller controls the lens ...

Abstract

The present invention relates to visual navigation system and method for intelligent endoscope. The system includes one endoscope, one lens deflecting mechanism, one automatic intervening mechanism, and one PC with image acquiring controller connected to the above said parts for processing image signal, displaying, and controlling lens deflection and automatic intervening. The system has simple composition, several manual and automatic switchable functions and convenient use; and the operation is fast, precise and timely.

Description

technical field [0001] The invention relates to an endoscope navigation system and method, in particular to an intelligent endoscope vision navigation system and method based on computer vision. Background technique [0002] Minimally invasive and non-invasive surgical technology is one of the most important development trends of contemporary clinical medicine. It can greatly improve the quality of surgery, reduce the pain of patients, and shorten the recovery time. It has become a research hotspot in the world. Traditional endoscopic diagnosis and treatment is an important means of minimally invasive surgery, and its typical equipment is endoscopic fiberscope and catheter, etc., which play an extremely important role in the diagnosis and treatment of lesions. [0003] In traditional endoscopy, the doctor watches a monitor that displays real-time images coming from the head of the endoscope. When the doctor pushes the endoscope into the bowel, he adjusts the angle by turnin...
