MACHINE VISION COUNTING SYSTEM APPARATUS AND METHOD

摘要

A machine-vision-based counter includes an image acquisition component (i mager), wherein light provides discrimination between a background field and imageable units located away from the imager. The imager outputs data repre senting the field and units; an image processor receiving imager data finds countable units therein. An operator interface accepts command inputs and pr esents count output. A controller manages image acquisition, processor and o perator interface functions. A counting method includes configuring an image r to detect light directing from a source to units positioned to be detected by the imager, and directing the light to the imager. The method includes d iscriminating between a background field and imageable units; providing, as an imager output, data representing the field and units; configuring an imag e processor to receive imager data; configuring the processor to interpret t he data as counted units on a background field; and configuring an operator interface to present a count result.
