In the teaching of physics is essential to have places where the student can assimilate and test the concepts learned from books. Often these labs are not enough not counting that external factors do not always get the desired results. Thus, is proposed to create a virtual lab linked to a real scenario using computer vision techniques (Direct Linear Transformation). Initially were measured position and time locating recognizable patterns in image sequences. Was obtained an uncertainty of ± 1.5 mm for the position, with a frequency of capture of 30 frames per second, which gives a time resolution of 33.3 ms.
