Abstract
La presente invención se refiere a un método para simular la visibilidad de un recubrimiento aplicado sobre una superficie para un sensor LiDAR, que comprende al menos las etapas siguientes: - aplicar el recubrimiento sobre la superficie (301); - medir un reflejo de luz respectivo con una longitud de onda de funcionamiento del sensor LiDAR desde la superficie recubierta con el recubrimiento a una multiplicidad de ángulos de iluminación y/o medición (302); - adaptar una función de distribución de la reflectancia bidireccional para el recubrimiento en función del ángulo de iluminación y/o medición respectivo a las respectivas reflexiones medidas (303); - simular una propagación de la luz emitida por el sensor LiDAR y reflejada por la superficie recubierta con el recubrimiento sobre la base de la función de distribución de reflectancia bidireccional adaptada mediante una aplicación de trazado de rayos (304), donde el sensor LiDAR es simulado como una unidad que comprende una fuente de luz puntual y una cámara, y donde la superficie recubierta con el recubrimiento es simulada como un perfil que está dispuesto a una distancia variable con una orientación variable delante de la cámara; - generar una imagen de luminosidad, que muestra una luminosidad de la luz reflejada por el perfil en la dirección del sensor LiDAR, mientras se tiene en cuenta la función de distribución de reflectancia bidireccional adaptada (305).
