Clear or Reflective Object Detection

Clear or Reflective Object Detection

Detecting transparent clear or shiny objects is one of the biggest challenges sensors face. Variations in target shape, size, material, color and translucence can complicate accurate detection. Light can burn through a target or be reflected away in erratic ways. Harsh, hazardous and washdown environments found in many applications not only challenge detection, but can dramatically shorten the lifespan and performance of a sensor. Banner offers several solutions designed and developed specifically to overcome the many challenges common to clear object detection.
