Implementación de un medidor de velocidad basado en visión artificial.

Abstract

This project presents an automatic method of vehicle speed measurement. It has the real data of its speed (observed in the tachometer), and this allows to obtain the error made by the method. Once the tests have been carried out, this technique can be applied to mediate the speed of any other object. To perform this speed measurement, it is required to have the distance traveled by the object and the time invested, both variables considering the field of view of the camera used. To obtain the distance covered by the camera's field of view, it was initially done manually depending on the scenario. Subsequently, its obtaining was automated using a laser meter that measures the distance perpendicular to the trajectory of the vehicle and, on the other hand, to the angle of the field of vision of the camera used that is also calculated experimentally. With both parameters, this distance from the field of vision is trigonometrically obtained. For the measurement of time an algorithm is used in Matlab considering the time from when it enters until the object of the field of vision of the camera comes out, based on these two parameters, distance and time, the object's speed is determined.
