A wide range of single-purpose point sensors such as proximity sensors, lasers and photocells have long played a key role in virtually all factory automation systems by detecting the presence of parts or assemblies, performing measurements, and identifying colors.
Since its early days, machine vision has been primarily used to check the liquid level in a bottle, or verify if a packaging label is applied correctly.
For several years now the technologies used in machine vision have gotten more sophisticated, and at the same time the applications for quality checks are solved with a new ease.
Machine vision technologies for Vision Guided Robotics (VGR) have greatly enhanced the flexibility and capability of robots in many industrial applications, expanding the value of robots in markets ranging from automotive to food to pharmaceutical to warehousing/distribution/order fulfillment.
The benefits of smart cameras have made them an ideal match for a manufacturing environment. Combining a camera, processor, software and communications in one small, low-power package, smart cameras are highly integrated optical inspection tools for controlling quality and increasing productivity—required tasks in manufacturing.
New computer vision applications are obtaining maximum image quality by combining high resolution, low-flare lenses with large format, high resolution global shutter sensors.
