Abstract

PROCEDIMIENTO PARA CALIBRAR UNA CAMARA (4, 22) DISPUESTA EN UN SOPORTE MOVIL (21). LA CAMARA COMPRENDE UNA IMAGEN DE UNA MIRA FORMADA POR ALMENOS TRES MARCAS QUE APARECEN EN EL CAMPO DE LA CAMARA Y EL ANALISIS DE LA IMAGEN PROPORCIONA LA POSICION Y LA ORIENTACION ORIGINALES DE LA CAMARA RESPECTO A LA DE LA MIRA QUE SE CONOCEN EN UNA APLICACION. EL SOPORTE (21) PUEDE ENTONCES DESPLAZARSE HACIA UN OBJETO (28) CUYA CAMARA TOMA IMAGENES. COMO LOS DESPLAZAMIENTOS DEL SOPORTE SE MIDEN CON PRECISION, EL ANALISIS DE LAS IMAGENES DEL OBJETO PROPORCIONA LA POSICION Y LA ORIENTACION PRECISAS DEL OBJETO RESPECTO A LA CAMARA Y RESPECTO A LA MIRA. UNA APLICACION ES LA INSPECCION DE PANELES DE CARRETERA (28) PARA CONSTITUIR BASES DE DATOS DE GESTION DE LA RED O PARA SISTEMA DE NAVEGACION EMBARCADO.
