System calibrates camera pixel size in vision systems
- April 8, 2015
- Product Release
- Testing and Measuring
Heidenhain Corp. offers the Magnification Checker tool to help machine vision users qualify the pixel size of any camera type.
Originally produced by Acu-Rite (now a Heidenhain brand), the unit features variably sized artifacts imprinted on its glass surface to allow users to view the images through a camera and lens system. Because of varying application requirements to measure different-sized features, multiple magnification levels are necessary. Using the system in tandem with evaluation electronics, users can change magnification levels and teach and store pixel sizes at each level.
