Abstract

Este dispositivo de reconocimiento de imágenes montado en vehículo detecta de manera fiable los cuerpos en movimiento de las imágenes capturadas, incluso cuando la lente está sucia. Una unidad (10) de captura de imágenes dispuesta en el vehículo (5) local observa la periferia del vehículo (5) local a través de una lente (12) y convierte en una señal de imagen la señal óptica de la periferia observada del vehículo (5) local. De las imágenes capturadas por la unidad (10) de captura de imágenes, una unidad (70) de detección de vehículo (unidad de ejecución de aplicación de reconocimiento de imagen) detecta otros vehículos (6) (cuerpos en movimiento) presentes en la periferia del vehículo (5) local con una sensibilidad de detección prescrita. Dependiendo de qué tan alta es la turbiedad blanca (U), una unidad (50) de ajuste de sensibilidad de detección ajusta la sensibilidad de detección de la unidad (70) de detección de vehículo en la dirección para mejorar la sensibilidad de detección. Una unidad (26) de cálculo de grado de adherencia calcula el grado de adhesión (M) de la materia adherida tal como gotas de agua o lodo que se adhiere a la lente (12), y las correcciones se hacen basándose en tal grado de adhesión (M) en tal unidad (50) de ajuste de sensibilidad de detección.
