Lighting - The Last Machine Vision Frontier
Machine vision is becoming a common tool on the manufacturing floor. Morphological operation, algorithm, grayscale analysis, correlation, blob tools, vectors, regions of interest and field-of-view (the area the camera sees) are commonplace terms among machine vision users. In just a few years, the focus of machine vision has changed from whether or not the vision system will actually work to whether to purchase brand X over brand Y and at what volume of discount. In fact, the words 'machine vision is a commodity item purchase', a dream for machine vision vendors in the 1980s, is a reality today.
Despite the advances of machine vision hardware, software, cameras and communication protocol, lighting for machine vision remains an art form for those involved with vision integration. The ability to look at a part and state with confidence the lighting technique required for feature extraction is rare, even among those with long term machine vision experience. Why is it that lighting remains so difficult, even though the majority of engineers recognise lighting as an important piece of the total machine vision solution? The reason is that, for the most part, a logical lighting selection workflow to guide us through the necessary steps for integrating the light has been, for the most part, non-existent. Light selection is mostly an afterthought to the vision system purchase.
