Area of Science:

Medical Imaging
Gastroenterology
Robotics

Background:

Accurate navigation is crucial for wireless capsule endoscopy (WCE) and microball camera systems.
Current methods may require multiple images or complex setups for directional information.

Purpose of the Study:

To propose a novel method for acquiring an intestinal direction vector (IDV) from a single static wireless endoscopic image.
To enable improved navigation and camera selection in endoscopic procedures.

Main Methods:

Lumen detection using Bayer-format downsample, adaptive threshold segmentation, and radial texture detection.
IDV calculation by modeling the small intestine and image capture process from a single image.

Main Results:

The lumen detection achieved 95.5% precision and 98.1% sensitivity.
Experiments in pig intestines showed the IDV error is within a sphere of radius 0.085.

Conclusions:

The proposed method effectively acquires IDV from a single endoscopic image.
This technique offers a promising solution for enhancing WCE navigation and multicamera system control.
