Abstract
El primer y segundo ángulos están medidos desde una línea central nominal de una cámara a respectivas primera y segunda posiciones. La primera posición está determinada por la cámara que ubica al primer punto central en un primer cartel. La segunda posición está determinada por la cámara que ubica al segundo punto central en un segundo cartel. El primer y segundo ángulos, y la primera y segunda distancias horizontales de la cámara desde el primer cartel y el segundo cartel, respectivamente, se usan para obtener una distancia vertical determinada y un ángulo determinado. La distancia vertical determinada mide una distancia desde el segundo punto central a un punto determinado por una intersección de una primera línea a través del segundo cartel y una segunda línea que es paralela al piso y tiene un punto final en la cámara. El ángulo determinado mide un ángulo de entre la tercera línea que se extiende desde la cámara en la posición nominal y la segunda línea.
