3D Scanning Inspection

This article discusses two types of 3D scanning: Structured Light and CT. It will broadly cover the advantages and disadvantages of each and some of the factors to consider in choosing a method for a particular application. Some considerations are scanner portability, characteristics of the objects to be scanned, scanner flexibility and limitations, inspection capabilities, and automation. Although we are looking at these only in a general sense, because there are many different types of CT and structured light scanners, these criteria should apply to the majority of scanners. However, we are just scratching the surface, offering an overview of some of the important points.
