This article describes the Metrovisionlab simulation software and practical sessions designed to teach the most important machine vision camera calibration aspects in courses for senior undergraduate students. By following a constructivist methodology, having received introductory theoretical classes, students use the Metrovisionlab application to carry out a series of practical exercises with the aim of learning in a simple way: 1) the basic functioning of a camera; 2) how to calibrate a camera; 3) the most important calibration methods and their special characteristics; and 4) the generation and use of synthetic calibration points. Evaluations based on student feedback confirm that the use of Metrovisionlab as a teaching tool facilitates the learning process. (Contains 5 figures and 1 table.)
