Intraoral Scanner Guide Path Overlay for Real-Time Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of intraoral scanners lack awareness and feedback on whether they are accurately following a scan guide, as the guide is typically provided separately and not integrated into the scanning process.
Innovation Solution
A method and device that display a guide scan path on the scan screen, track the user's scan path, and compare it to the guide path in real-time, providing feedback and warnings for accurate scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the scan guide is provided in a separate document or on a web page, then the scanning strategy can be provided to users, but users cannot check whether photographing is performed according to the scan guide in real-time
Solution Approach 1:
The patent merges the scan guide information with the scanning interface by displaying the guide scan path directly on the scan screen alongside the user scan path. This integration allows users to simultaneously view both the recommended scanning route and their actual scanning progress, enabling real-time verification without needing to refer to separate documents or web pages.
Solution Approach 2:
The system provides visual feedback by overlaying the guide scan path and user scan path on the same display. Users can immediately see whether their scanning follows the recommended path, receiving continuous feedback during the scanning process rather than discovering deviations after completion.
2Measurement precision
If the guide scan path is displayed on the scan screen, then users can check scanning alignment, but the system complexity increases
Solution Approach 1:
The system creates a visual copy of the guide scan path and displays it alongside the user scan path on the scan screen. This copying approach allows direct visual comparison between the recommended path and actual path, improving alignment accuracy assessment without requiring complex analytical processing.
Solution Approach 2:
The display system acts as an intermediary that visually represents both the guide scan path and user scan path in a comparable format. This intermediary representation enables users to assess alignment accuracy through visual inspection rather than requiring complex computational analysis.
3Reliability
If the user scan path is tracked and displayed together with the guide scan path, then users receive real-time feedback on scanning accuracy, but the processing time and computational resources increase
Solution Approach 1:
The system continuously tracks and displays the user scan path alongside the guide scan path throughout the scanning process. This continuous visual feedback maintains scanning accuracy verification without requiring additional processing time after scanning completion, as the comparison occurs in real-time during the scanning operation itself.

AI summary
Disclosed are a scan guide providing method and an image processing device therefor. A scan guide providing method according to an embodiment comprises the steps of: displaying, on a scan screen, a guide scan path for providing a scanning strategy of an intraoral scanner; tracking a user scan path actually scanned, along the guide scan path, by the intraoral scanner; and displaying the tracked user scan path together with the guide scan path.
