Abstract

Un método para calibrar un dispositivo de escáner óptico implementado por un aparato de gestión de calibración, que incluye brindar instrucciones al dispositivo de escáner óptico para escanear una superficie de calibración en un patrón de escaneo basado en uno o más parámetros de escaneo, donde uno o más parámetros de escaneo varían a través del patrón de escaneo. El ángulo de escaneo para cada uno de los múltiples puntos en el patrón de escaneo se computa en función de una imagen obtenida de una fuente de luz emitida desde el dispositivo de escáner óptico en un ángulo de escaneo para múltiples puntos en el patrón de escaneo. Una relación de calibración entre los ángulos de escaneo computados y los parámetros de escaneo correspondientes se determina para cada uno de los múltiples puntos en el patrón de escaneo.
