In this section, we will introduce you to the first step of any AOI algorithm, that is, isolating different parts or objects in a scene.
We will take the example of object detection and classification of three object types: a screw, a packing ring, and a nut and develop these in this chapter and Chapter 6, Learning Object Classification.
Let's say we are in a company that produces these three objects. All of them are in the same carrier tape, and our objective is to detect each object in the carrier tape and classify each one to allow a robot to put each object on the correct shelf:
In this chapter, we will isolate each object and detect its position in the image in pixels. In the next chapter, we will classify each isolated object to check whether it is a nut, a screw, or a packing ring.
In the following image, we show our desired result where there are a few objects in the left-hand side image, and in the right-hand side image, we draw each one in different colors...
