Abstract

Se revela un sistema y un método para calibrar una cámara de profundidad en una interfaz de usuario natural. De manera general, el sistema obtiene una medición objetiva de la verdadera distancia entre un dispositivo de captura y uno o más objetos en una escena. El sistema compara luego la verdadera medición de profundidad con la medición de profundidad proporcionada por la cámara de profundidad en uno o más puntos y determina una función de error que describe un error en la medición de la cámara de profundidad. Posteriormente, se puede recalibrar la cámara de profundidad para corregir el error. La medición objetiva de la distancia a uno o más objetos en una escena puede ser realizada por una variedad de sistemas y métodos.
