Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional scanners in dentistry face challenges in accurately acquiring data due to obstacles like fingers or tongues entering the scanning area, requiring manual selection and correction of data, which is time-consuming.
Innovation Solution
A data processing apparatus and method that verifies three-dimensional data by comparing data sets acquired at different times using a virtual space set with respect to the scanner's position, automatically identifying and correcting for obstacles by aligning and comparing data sets to determine true data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual selection and correction of three-dimensional data is performed to remove obstacles, then data accuracy is improved, but time consumption and operational complexity increase
Solution Approach 1:
The system performs preliminary comparison and verification of three-dimensional data sets before final data selection. By comparing multiple data sets acquired at different times and identifying consistent features, the system pre-filters out obstacle data, so that when data correction is needed, the work has already been substantially completed through automated comparison.
Solution Approach 2:
The system enables self-service by automatically comparing multiple three-dimensional data sets, identifying obstacles through verification processes, and selecting valid data without requiring manual intervention. The data processing apparatus autonomously performs the verification and selection tasks that previously required operator involvement.
