Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional measurement devices for oral cavities face challenges in achieving high precision while minimizing data amount and processing load, often resulting in inefficient scanning processes due to the need for multiple directional scans, which can increase data and processing loads without ensuring precise results.
Innovation Solution
A method and device that detect measurement information-insufficient sites within the oral cavity, notify a re-measurement start position, and re-scan these areas with adapted characteristic sites to create high-precision three-dimensional measurement information, thereby optimizing the measurement process and reducing unnecessary data and processing loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If scanning is performed in multiple directions to ensure complete coverage of the measurement target, then measurement precision is improved, but data amount and processing load increase
Solution Approach 1:
The patent segments the measurement process into initial scanning and selective re-scanning phases. Instead of uniformly scanning the entire measurement range in multiple directions, the system identifies specific measurement-insufficient sites and directs re-scanning only to those areas, thereby maintaining precision while reducing overall data volume
Solution Approach 2:
The patent applies local quality by differentiating between measurement-sufficient and measurement-insufficient sites within the measurement range. Re-scanning is applied selectively only to insufficient sites rather than uniformly across the entire range, optimizing the balance between precision and data reduction
2Measurement precision
If scanning is performed in multiple directions to capture complete three-dimensional information, then measurement precision is improved, but measurement time increases
Solution Approach 1:
The patent performs preliminary scanning to identify measurement-insufficient sites before conducting re-scanning. This preliminary action allows the system to plan the re-scanning process efficiently, avoiding unnecessary scanning in areas that have already been adequately measured
Solution Approach 2:
The patent applies partial action by performing re-scanning only on measurement-insufficient sites rather than re-scanning the entire measurement range. This selective approach maintains measurement precision for critical areas while significantly reducing total measurement time
3Quantity of substance
If re-measurement is performed on only the measurement-insufficient site, then data amount and processing load are reduced, but synthesis precision between initial and re-measurement results decreases
Solution Approach 1:
The patent uses feedback mechanisms to evaluate measurement sufficiency at each site and dynamically adjust the re-scanning process. The system continuously monitors measurement quality and directs re-scanning to specific sites where insufficiency is detected, ensuring synthesis precision is maintained through targeted data collection
Solution Approach 2:
The patent introduces characteristic sites as intermediaries to facilitate accurate synthesis between initial and re-measurement results. These characteristic sites serve as reference points that enable precise alignment and integration of measurement data from different scanning phases

AI summary
Provided is a three-dimensional measurement method and a three-dimensional measurement device preventing increase in data amount and processing load and providing a highly precise measurement result. According to a three-dimensional measurement method for performing three-dimensional measurement on a desired measurement range H in an oral cavity, a re-measurement start position Rs, at which re-measurement on measurement information-insufficient sites Lm and Ln is to be started, is displayed; re-measurement is performed on an area starting from the re-measurement start position Rs and encompassing the measurement information-insufficient sites Lm and Ln; and a characteristic site in the re-measurement information acquired by the re-measurement and a characteristic site in measurement information are adapted to each other to create three-dimensional measurement information on the measurement range H. The measurement information-insufficient sites Lm and Ln are detected in a measurement information-insufficient site detection process (step s6) of detecting the measurement information-insufficient sites Lm and Ln, for which measurement information acquired in a three-dimensional measurement step (step s5) is insufficient. The three-dimensional measurement step is of performing three-dimensional measurement on a measurement range H.
