The subject introduces methods of 3D computer vision. First, in three lectures, we summarize the necessary concepts of digital image processing / analysis. We follow with the description of one (intensity, RGB) camera and related geometry. We will learn how to use two or more cameras to determine the depth in the scene and for 3D reconstruction. We will add further depth sensory modalities, namely lidars, radars, sonars. We will explain how to combine information from a variety of sensors. We will practically illustrate the methods in the tasks associated with self-driving cars.
