Color imaging in machine vision: how to choose the right camera for your application. The challenges, the options, and the role of camera technology.
For many years, most machine vision systems only operated in black-and-white. Even today, the majority of machine vision applications are still monochrome. Yet there are a growing number of applications where color imaging is both required and can provide significant advantages.
The use of color in machine vision applications has increased significantly in the past ten years. This has been accompanied by steady improvements in both the camera technology and the algorithms to support color machine vision applications. As a result, many more machine vision system designers are finding themselves facing new challenges as they embark on building systems where color is a critical factor.
