Embodiment Construction

[0026] figure 1 It shows that a specific process of the method for generating a full-view image of a human body cavity based on a capsule endoscope image of the present invention is as follows:

[0027] 1. Obtain the pictures of the capsule endoscope and the format of the pictures: download the pictures taken by the capsule to the computer, and obtain the data and picture formats, such as BMP format.

[0028] 2. Preprocess the acquired pictures: eliminate all black and invalid images, and process blurred images. Here, the adaptive neighborhood averaging method with correction is used to eliminate image interference and noise, and the histogram equalization is used to Adaptive correction of image grayscale.

[0029] 3. figure 2 shows the process of generating full-view image of the present invention

[0030] The specific steps are: sequentially perform circular image expansion, image registration, and image splicing on the acquired pictures, and the spliced ​​image is a ful...

Abstract

The invention discloses a method for generating a body cavity full-view image based on capsule endoscope images, which comprises the following steps of: acquiring the capsule endoscope images and the image format; preprocessing the acquired images; generating the full-view image, wherein the acquired images are respectively subjected to circular image expansion, image registration and image mosaicking and the image obtained after mosaicking is the full-view image; and visually displaying the full-view image. By acquisition of the full-range cavity image through an endoscope, doctors can acquire more open and intuitive visual field during the diagnose, thereby the method is favorable to improve the accurately diagnostic rate of the doctors and shorten the image reading time.

Description

technical field [0001] The invention relates to an image processing method, in particular to a method for generating a full-view image of a human cavity based on a capsule endoscope picture. Background technique [0002] The wireless capsule endoscope, which appeared for the first time in 2000, has been widely used in the diagnosis of digestive tract diseases because of its painless inspection process and the ability to observe the entire digestive tract, and has become an important means of digestive disease inspection. Of course, there are some problems in the use of capsule endoscopes. For example, about 50,000 digital images can be generated during patient examination. All these pictures need to be interpreted by a diagnostician. The workload is huge, the diagnostic efficiency is low, and misdiagnosis and missed diagnosis are prone to occur. This has become a bottleneck restricting the development of capsule endoscopy technology recognized by experts. [0003] In order ...
