Dimensional Acquisition Feedback for Measurement Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for dimensional acquisition in reverse engineering and inspection tasks often result in incomplete or inaccurate data due to unskilled operators lacking feedback on acquisition quality, leading to inefficiencies and the need for re-measurement or excessive data collection.
Innovation Solution
A method and computer program that provides continuous feedback during the acquisition process, using a 'coverage module' and 'feedback module' to indicate regions of sufficient or insufficient resolution on a CAD model, guiding the measurement device to areas needing further data acquisition, ensuring adequate resolution for inspection or reverse engineering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual dimensional measurement is performed without feedback on acquisition quality, then the measurement process can proceed freely, but the acquired data may be incomplete or inaccurate
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors acquisition quality during the measurement process and provides real-time guidance to the operator. The system evaluates whether acquired regions meet predefined quality criteria and directs the operator to specific areas requiring additional measurement, thereby ensuring measurement precision without requiring advanced operator expertise
Solution Approach 2:
The measurement system performs self-evaluation of acquisition quality by automatically assessing whether acquired regions satisfy predefined criteria. The system independently identifies deficient areas and guides its own operation, reducing dependence on operator skill while maintaining high measurement standards
2Reliability
If excessive data collection is performed to ensure coverage, then complete data acquisition is achieved, but the measurement time and data processing load increase
Solution Approach 1:
The system applies partial action by measuring only the specific regions that require measurement to achieve sufficient coverage. Rather than uniformly measuring entire surfaces, the system identifies and targets only deficient areas, avoiding unnecessary measurements while ensuring data completeness
Solution Approach 2:
The system performs preliminary evaluation of acquisition quality during the measurement process itself, rather than waiting until completion. By continuously assessing coverage and identifying deficient regions in real-time, the system can immediately direct additional measurements to appropriate areas, preventing incomplete data acquisition without requiring post-processing or re-measurement
3Measurement precision
If continuous feedback on acquisition resolution is provided, then the operator can target regions needing improvement, but the system complexity increases
Solution Approach 1:
The system provides continuous feedback on acquisition resolution by evaluating whether acquired regions meet predefined quality criteria and communicating this information to the operator. This feedback loop enables the operator to efficiently target regions needing improvement without requiring complex manual assessment procedures
Solution Approach 2:
The system manages complexity by establishing predefined quality criteria parameters that automatically evaluate acquisition resolution. By converting the complex judgment of data quality into measurable parameters against established standards, the system achieves precise resolution control through straightforward computational evaluation rather than complex analytical processes

AI summary
The present invention relates to a method for improving the efficiency of dimensional acquisition of an object by a dimensional measurement device directed over the object, comprising the steps: a) directing the measurement device over the object to acquire its dimensions, b) providing an indication of the resolution of the acquired regions, c) re-directing the measurement device over at least part of the acquired regions indicating insufficient resolution according to predetermined criteria, d) updating the indication of the resolution of the acquired regions, and e) repeating steps c) and d) until sufficient resolution is indicated according to the predetermined criteria, thereby efficiently acquiring the dimensions of the object at sufficient resolution. It also relates to a computer program therefor.
