If we apply a sequence of 3D rotations to an objects we see that the order in which they are applied affects the final result.

We learn how to describe the 2D pose of an object by a 3×3 homogeneous transformation matrix which has a special structure. Try your hand at some online MATLAB problems. You’ll need to watch all the 2D “Spatial Maths” lessons to complete the problem set.

We recap the important points from this lecture.

When matching points between scenes with large different viewpoints we need to account for varying image size and rotation. SIFT features are a powerful way to achieve this.

We summarise the important points from this lecture.

We use MATLAB and some Toolbox functions to find corresponding points between two images using SURF features.

We consider a robot, which has two rotary joints and an arm.

We will learn how to create coordinate frames that have smoothly changing position and orientation over time.

Now we introduce a variant of the Jacobian matrix that can relate our angular velocity vector back to our rates of change of the roll, pitch and yaw angles.

A body moving in 3D space has a translational velocity and a rotational velocity. The combination is called spatial velocity and is described by a 6-element vector.
