\nEngineer Jon explained why vision inspection systems<\/a> can\u2019t do everything you want.<\/p>\n

How the Human Brain Processes Images
\nYour brain is a pattern recognizing machine. Primed with a lifetime of learned patterns, it can quickly identify and categorize nearly anything you can see. Even when pictures aren\u2019t clear, you can probably make a good guess just based on context. You know where you are, what you\u2019re looking for, and you\u2019ve got the additional benefit of all your other senses.<\/p>\n

When you\u2019re considering a vision inspection task, you also have deep knowledge about the product you\u2019re inspecting, the process that created it, and the things that can go wrong. That helps immensely in determining if something is a good part or reject.<\/p>\n

Unlike a computer, your brain is very flexible and readily learns from experience. You can quickly and effortlessly learn new product categories or defect types. You can recognize patterns without having to be taught. If you don\u2019t see what you\u2019re looking for in the place you expect, you\u2019ll look elsewhere. Even fuzzy or distorted images are recognizable to the human brain, and you\u2019ll usually get better over time.<\/p>\n

\"\"<\/p>\n

While the human brain is supreme when it comes to pattern recognition (also called categorization in vision systems), it has some limitations. It can be inconsistent from person to person or day to day, sometimes slow, and it\u2019s not numerical, so things like measurement from visual inputs are difficult.<\/p>\n

How Industrial Vision Inspection<\/a> Works
\nOn the other hand, when you\u2019ve got an automated vision inspection system, it only knows what you tell it. It has no idea about the process or the part, no stored bank of patterns to recognize, no awareness of context, and no other senses.<\/p>\n

The programmed system is very rigid in its approach to finding, categorizing, and measuring features. Each step of the process has to be specifically set up by the programmer, so it won\u2019t improve over time without help, it won\u2019t learn new patterns, and it won\u2019t look anywhere else if it doesn\u2019t find what it\u2019s looking for.<\/p>\n

This ridgid approach has its benefits, as well. It tends to be fast, consistent, and numerical, all important features for industrial processes. It\u2019s also very good at measurement tasks.<\/p>\n

Simplicity is important for automated inspection<\/a>. Setup the camera and lighting to collect images with high contrast on the features of interest and low contrast on everything else. This helps simple algorithms (compared to your brain) to be effective. Simple algorithms process faster, and they\u2019re more feasible from a programming perspective.<\/p>\n
