Abstract

The invention discloses a two-dimensional plane representation method for the images of the intestinal tract. The realization of the method is based on a wireless sacculus endoscope system in which an attitude motion sensing module and an intestinal cavity identifying module are embedded. The method comprises several following steps: reading images; classifying an image set into turbid images and non-turbid images; dividing a non-turbid image set into a plurality of subsets; calculating the relative position relationship of a camera and the wall of the intestinal tract when shooting each image; carrying out the treatment of rectifying or mapping on the images; carrying out registered splicing or similar matching on the images after being rectified or mapped; and combining the subsets to form a two-dimensional expansion drawing of the wall of the intestinal tract. By adopting the two-dimensional representation method for the images of the intestinal tract, which is provided by the invention, the redundant contents of images collected by a wireless endoscope can be greatly reduced. The two-dimensional plane representation method for the images of the intestinal tract is beneficial for a doctor to comprehend the images, the working difficulty of the doctor can be lowered, and the film reading efficiency is enhanced.

Description

technical field

[0001] The invention relates to the technical field of auxiliary equipment for clinical observation and diagnosis of intestinal diseases, in particular to a two-dimensional representation method of digestive tract images. Background technique

[0002] In the past ten years, with the rapid development of microelectronics, micromechanics, information processing, wireless communication and other technologies, the development of medical endoscope technology has been greatly promoted. Represented by the Wireless Capsule Endoscopy system (Wireless Capsule Endoscopy), the inspection of the human digestive tract, especially the small intestinal cavity, can be completed by the subject swallowing a capsule with a built-in wireless function micro-camera. The unique advantage of this technology is that it not only achieves painless diagnosis, but also breaks through the limitation that conventional endoscopes cannot directly inspect the small intestine. Currently, it is...
