Intraoral Panoramic Image Stitching for Full Teeth Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intraoral imaging devices have limited field of view, making it difficult to identify the position and type of each tooth and the relationship between teeth, limiting comprehensive observation of dental lesions and surrounding teeth.
Innovation Solution
An intraoral imaging apparatus and method that generates an optical panoramic image by stitching multiple individual images along the teeth arrangement direction, integrating optical and X-ray panoramic images for comprehensive dental observation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an intraoral camera is used to capture individual tooth images, then detailed images of individual teeth can be obtained, but the field of view is limited and only one to three teeth can be displayed in a single image, making it difficult to identify the position and type of each tooth and the relationship between teeth
Solution Approach 1:
The patent divides the comprehensive dental observation task into two segments: individual tooth image capture (using intraoral camera for detailed views) and panoramic image generation (stitching multiple individual images together). This segmentation allows each component to excel at its specific function while the combination provides the complete solution.
Solution Approach 2:
The patent merges multiple individual tooth images into a single panoramic image that displays the entire teeth arrangement. By combining the detailed images from the intraoral camera with stitching technology, the system achieves both high detail quality and comprehensive field of view.
2Area of stationary object
If multiple individual images are captured to show more teeth, then the field of view increases, but it becomes difficult to identify the position and type of each tooth and the relationship between individual images
Solution Approach 1:
The patent introduces tooth arrangement information as an intermediary element that bridges individual tooth images and the panoramic view. This intermediary provides contextual information about tooth positions and types, enabling accurate identification and relationship understanding across the expanded field of view.
Solution Approach 2:
The patent adds a contextual dimension to the panoramic image by integrating tooth arrangement information. This transforms the panoramic image from a simple composite view into an informative display that includes positional and identification data, allowing users to understand tooth relationships in the expanded field of view.
3Measurement precision
If individual tooth images are captured separately, then detailed observation of each tooth is possible, but comprehensive observation of dental lesions and surrounding teeth relationships is difficult
Solution Approach 1:
The patent merges multiple individual tooth images into a single panoramic image that provides comprehensive view of all teeth and their relationships. This merging maintains the detailed information from individual images while adding the context of tooth arrangements and relationships, enabling both precise lesion detection and convenient comprehensive observation.

AI summary
Proposed is an intraoral image displaying method. The intraoral image displaying method may include storing a plurality of optical images for the intraoral cavity including a teeth arrangement, generating an optical panoramic image for the entire teeth arrangement by stitching the plurality of optical images along a teeth arrangement direction, and displaying the optical panoramic image.
