Abstract

Se describe un método para generar datos de entrenamiento. El método puede incluir ejecutar un proceso de simulación. El proceso de simulación puede incluir cruzar una cámara virtual a través de un entorno de conducción virtual que comprenda al menos una condición de precipitación virtual y al menos una condición sin precipitación virtual. Durante el cruce, la cámara virtual puede moverse con respecto al entorno de conducción virtual tal como lo determina un modelo de movimiento de vehículo que modela el movimiento de un vehículo en conducción a través del entorno de conducción virtual mientras transporta la cámara virtual. Se pueden registrar los datos de sensor virtual que caracterizan el entorno de conducción virtual tanto en condiciones de precipitación virtual como en condiciones sin precipitación virtual. Los datos de sensor virtual pueden corresponder a lo que produciría un sensor real de haber detectado el entorno de conducción virtual en el mundo real.
