Image Sensors Used to Stably Determine Marking Failures of Workpieces on Rapidly Conveyed Lines
Case Number 237
last update: April 18, 2011
This Image Sensor has improved pattern matching. Stable detection of markings is performed even when detecting two dates, such as the manufacturing date and the use-by date on rapidly moving workpieces.
Know-How
The unique image processing circuits support high-speed lines performs matching with models dividing images into smaller parts. Subtle differences that cannot be determined by conventional pattern matching are detected as large numerical values.
Benefit / Efficiency
A single Image Sensor is used to inspect markings of two dates.
