Capsule Endoscopy 3D Panoramic View Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display systems for capsule endoscopes are inefficient, requiring examiners to manually review numerous images, leading to prolonged examination times, fatigue, and potential errors due to lack of spatial information about the capsule's position and posture during image capture.
Innovation Solution
A display system that converts multiple images from a capsule endoscope into 3D panoramic views, incorporating a 3D mini-map to visualize the capsule's path and position, providing a wider viewing angle and enhancing examination accuracy by generating a 3D panoramic view using image grouping, homography calculation, transformation, and blending algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If capsule endoscope continuously captures images during passage through organs, then comprehensive organ examination is achieved, but examination time and examiner fatigue increase significantly
Solution Approach 1:
The patent segments the large number of captured images into meaningful groups based on spatial location and temporal sequence. By organizing images into structured datasets with metadata about capsule position and orientation, the system enables examiners to review representative images from each segment rather than every individual image, significantly reducing review time while maintaining examination completeness.
Solution Approach 2:
The patent introduces spatial dimensionality by incorporating capsule position and posture information into the image display system. This allows images to be contextualized within a 3D representation of the organ cavity, enabling examiners to understand spatial relationships and navigate through the examination data more efficiently, reducing the time needed to correlate images with anatomical locations.
2Reliability
If capsule endoscope captures numerous images for thorough examination, then diagnostic accuracy improves, but examiner workload and potential for errors increase
Solution Approach 1:
The patent performs preliminary organization and structuring of image data before examination. By pre-processing the image dataset to include spatial metadata, temporal sequencing, and systematic grouping, the system prepares the data in an optimized format that reduces examiner workload during actual review. This preliminary structuring enables faster navigation and more accurate diagnosis without requiring examiners to manually organize numerous images.
3Device complexity
If traditional capsule endoscope system is used without spatial information, then device simplicity is maintained, but ability to recognize capsule position and posture is lost
Solution Approach 1:
The patent introduces spatial metadata and position information as an intermediary layer between the capsule endoscope and the image display system. Rather than fundamentally altering the capsule device, the system adds a processing layer that correlates captured images with spatial coordinates and capsule orientation data. This intermediary approach provides comprehensive spatial information while maintaining relative system simplicity through software-based solutions.

AI summary
The present disclosure relates to a display system including a capsule image view, a 3D mini-map, and a 3D panoramic view, and a method of generating a 3D panoramic view. Specifically, according to the present disclosure, it is possible to infer the shape of an organ using a 3D mini-map and to simultaneously identify whether or not the capsule endoscope captures the images, and information on the position and posture of the capsule endoscope at primary captured points by visualizing the actual movement path of the capsule endoscope, thereby improving the accuracy of examination, and since multiple 2D images captured by a single capsule endoscope are able to be viewed as a single 3D panoramic image without changing the structure of the capsule endoscope, it is economical and the viewing angle of the image is able to be increased, thereby reducing the examination time and fatigue of the examiner.
