Abstract

Una modalidad de la presente invención establece una técnica para realizar corrección de perspectiva en una o más imágenes de prueba. La técnica incluye analizar una primera imagen de prueba para detectar un conjunto de puntos externos y calcular una ecuación de plano geométrico basada en el conjunto de puntos externos. La técnica además incluye proyectar un primer conjunto de puntos asociados con un primer modelo de pantalla curva basado en la ecuación de plano geométrico para generar un segundo conjunto de puntos. La técnica además incluye comparar el segundo conjunto de puntos con un conjunto de puntos internos incluidos en la primera imagen de prueba para determinar al menos un valor de error, y determinar un valor de curvatura de pantalla basado en al menos un valor de error.
