Despite their use across numerous industries, the terms ‘accuracy’, ‘precision’, ‘resolution’ and ‘repeatability’ are used almost interchangeably by suppliers and users alike. However, each of these terms represents a very specific characteristic of any measurement system. Understanding the differences between each one is critical to understanding if a given system will work for a given application. This presentation will define the differences between each measurement. From there a series of real world scans will be used to clearly demonstrate the difference between these characteristics. I.e. scans with high accuracy and low resolution; low accuracy and high resolution, etc. A series of potential applications will be provided with recommendations on which specifications matter and when. Finally, we will review the types of tests a user can perform to validate their 3D scanner’s performance as well as examples of similar techniques and tools are used to manufacture a 3D scanner.
