We recap the important points from this masterclass.
How is an image formed? The real world has three dimensions but an image has only two. We can use linear algebra and homogeneous coordinates to understand what’s going on. This more general approach allows us to model the positions of pixels in the sensor array and to derive relationships between points on the image […]
Many technologies have been developed to determine the 3D-structure of the world. RGBD sensors such as the Kinect use structured light, projecting a pattern of light onto the scene and observing how it is distorted. Time of flight sensors measure the time it takes for a pulse of light to travel from the camera to […]
Let’s recap what robots are, where they’ve come from and what they can do. Robots use sensors to understand their world and plan an action to achieve their goal.
Why do robots need a sense of vision in this modern age when GPS satellites can tell a robot where it is? Let’s talk about GPS, how it works and its strengths and weaknesses such as multipath and urban canyon effects.
All animals have a variety of senses that help them in everyday life. We’ll talk about interesting non-human senses that some animals possess and the often overlooked human sense of balance which is based on accelerometers and gyroscopes in our vestibular system.
We learn how accelerometers and gyroscopes can be combined into an inertial navigation system capable of estimating position and orientation of a vehicle, without GPS.
