3D Scanner Data Processing for Dental Obstacle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional scanners in dentistry face challenges in acquiring accurate data due to obstacles like fingers or instruments entering the scanning area, requiring users to manually select and correct data, which is time-consuming and labor-intensive.
Innovation Solution
A data processing apparatus and method that automatically processes three-dimensional data by generating data sets with the largest data amount as true data, excluding obstacles and ensuring accurate surface representation of objects, using a scanner interface and processing circuitry to differentiate between true and false data sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual selection and correction of three-dimensional data is performed by the user, then accurate data can be obtained by excluding obstacles, but the process requires a lot of time and effort
Solution Approach 1:
The system performs automatic data verification and selection without requiring user intervention. The verification unit autonomously analyzes multiple three-dimensional data sets, determines their validity based on predetermined conditions, and selects the most appropriate data set, enabling the system to serve itself rather than requiring manual user correction
Solution Approach 2:
The patent replaces the manual mechanical process of user selection and correction with an automated computational verification system. The verification unit uses algorithmic processing to evaluate data sets and determine their validity, substituting human manual operations with automated information processing
2Reliability
If multiple three-dimensional data sets are generated and manually evaluated, then the true data set can be identified, but the complexity of the process increases
Solution Approach 1:
The verification unit implements a feedback mechanism that automatically evaluates generated three-dimensional data sets against predetermined conditions and provides feedback on their validity. This automated feedback loop enables the system to identify and select the true data set without manual intervention, maintaining reliability while reducing processing complexity
3Productivity
If automatic data processing is implemented to reduce user effort, then time and labor are reduced, but the system complexity increases
Solution Approach 1:
The system performs preliminary verification and validation of three-dimensional data sets during the acquisition process itself. By预先 establishing predetermined conditions and automatically verifying data sets as they are generated, the system eliminates the need for subsequent manual correction processes, thereby improving productivity without requiring complex post-processing systems
