Detector Arrays: Taming the Irregular Shape Problem

Facebook Twitter LinkedIn Email Comments

Devices that perform well under laboratory conditions often face hurdles in uncontrolled real-world situations. This is true for charge-coupled devices (CCDs) and thermal cameras used in machine vision applications where an object's shape, location and orientation vary. Often the culprit is the detector array.

Gerald C. Holst, JCD Publishing

If we were to estimate the output of a CCD or thermal camera, we would typically draw an image over the detectors, aligning the image with the detector axes. We show it this way because it’s easy to draw; using quadrille graph paper, we simply follow the lines. In addition, symmetrical figures are easy to analyze. In the lab we can align a target with the detector array and easily verify our symmetrical drawings experimentally. Not so in the real world. Take, for example, a web inspection facility where parts are randomly located on a moving conveyor belt. Here, the image can fall...Read full article
