Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In endoscopic examinations, doctors face challenges in accurately diagnosing targets by viewing endoscopic images from different positions and directions, which limits their understanding of biological surfaces or internal structures.
Innovation Solution
An image processing system that generates three-dimensional data from a series of endoscopic images, allowing for the creation of two-dimensional images from desired viewpoints, enabling precise diagnosis by displaying these images on a display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If doctors view endoscopic images from the original capture position and direction, then the images are readily available for diagnosis, but the understanding of concavities and convexities on the biological surface is limited
Solution Approach 1:
The patent applies dimensionality change by transitioning from two-dimensional endoscopic images to three-dimensional reconstructed data. This allows doctors to view the observed target from multiple angles and directions by generating two-dimensional images from different viewpoints based on the three-dimensional data, thereby improving diagnostic accuracy while maintaining ease of access to image data.
2Adaptability or versatility
If multiple endoscopic images are captured to enable viewing from different positions, then viewpoint flexibility is improved, but the complexity of image management and processing increases
Solution Approach 1:
The patent uses copying by creating a three-dimensional data model that replicates the spatial structure of the observed target. Instead of managing multiple original endoscopic images, the system generates virtual two-dimensional images from this three-dimensional copy, allowing flexible viewpoint changes without the complexity of managing and processing numerous captured images.
Solution Approach 2:
By transforming multiple two-dimensional endoscopic images into a single three-dimensional data structure, the system reduces image management complexity. The three-dimensional data serves as a consolidated representation from which infinite two-dimensional views can be generated, simplifying the overall image processing workflow.
3Measurement precision
If three-dimensional data is generated from multiple endoscopic images, then diagnostic accuracy is improved, but the processing time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by generating the three-dimensional data model in advance during the endoscopic examination procedure. Once the three-dimensional data is created, it can be stored and reused for multiple diagnostic sessions without requiring repeated processing of the original endoscopic images, thereby reducing processing time in subsequent diagnostic activities.
