Vision sensors can solve many non-contact inspection and measurement problems, replace complex sensor arrays, provide feedback to robotics, and solve problems where machine vision was once thought too expensive and complex.
Some of the more obvious uses for a vision sensor would be for traditional vision applications. But due to ease of use, lower cost, and functionality, vision sensors can also be applied to applications that traditionally use mechanical gauging or sensor technology. Measurement sensors, proximity and photoelectric sensor arrays, or mechanical gauges that perform inspection and measurement can, in many applications, be replaced by a single ...
