Abstract
UN APARATO DE BUSQUEDA DE DISTANCIA INCLUYE UN PAR DE CAMARAS SEPARADAS QUE PROPORCIONAN SEÑALES QUE SON DIGITILIZADAS, ALMACENADAS EN MEMORIAS INTERMEDIAS DE MARCO Y PROPORCIONADAS A UN COMPUTADOR QUE PROPORCIONA UN MAPA DE DISTANCIAS DE UN OBJETO DE BLANCO VISTO POR LAS CAMARAS.EL COMPUTADOR OPTIMIZA UNA FUNCION DE DISPARIDAD REDUCIENDO AL MINIMO UN COSTE FUNCIONAL, CON LO QUE SE AVERIGUA LA DISTANCIA EN DIFERENTES PUNTOS DE LA SUPERFICIE DEL OBJETO DE BLANCO EN BASE A VARIACIONES DE ILUMINACION, REFLECTIVIDAD Y TEXTURA.
