Let’s look at some recent research results that vividly show how information from many 2D images taken from many different locations can be combined to form a detailed 3D model of the world.

Let’s recap the important points from the topics we have covered in our discussion of optical flow and visual servoing.

An image is a two dimensional projection of a three dimensional world. The big problem with this projection is that big distant objects appear the same size as small close objects. For people, and robots, it’s important to distinguish these different situations. Let’s look at how humans and robots can determine the scale of objects […]

Seeing is an active process and our brain uses our eyes to find answers to questions — how we look at a scene depends on what we want to know. Eye tracking experiments measure where eye movement, where we look and what we pay attention to.

Vision is a critically important sense for humans and, in fact, for almost all animals. If it’s useful to us then surely it would be a useful sensor for robots.

An important problem in robotic vision is moving a camera so that the view it sees matches the view we want it to have. To achieve this we exploit knowledge about how an image changes as a camera moves. Then we invert that and compute how the camera should move so the image changes in […]

We will compare and contrast the terms image processing, computer vision and robotic vision — they have much in common but there are some subtle but important distinctions. When it comes to interpreting an image we typically try to find and describe regions, lines and interest points.
