Abstract

Un método y aparato para identificación de área se proveen en la descripción, que pertenece al campo técnico de procesamiento de imagen. El método puede comprender: identificar un borde predefinido en una imagen de identificación, en donde el borde predefinido es un borde ubicado en una dirección predefinida de la identificación; determinar uno de n candidatos de borde predefinido para ser un borde predefinido de destino cuando se han identificado los n candidatos de borde predefinido, en donde n = 2; identificar por lo menos un área de información en la imagen de identificación con base en el límite predefinido de destino. Puede resolver los problemas en la técnica relacionada de que es difícil identificar algunas áreas de información en la imagen de identificación obtenida directamente por fotografía y que las posiciones de algunas áreas de información son inexactas, y puede lograr el efecto de ubicar las áreas de información con exactitud al determinar el borde predefinido de destino con base en los n candidatos de borde predefinido en la imagen de identificación y determinar por lo menos una información con base en el borde predefinido de destino. [Figura 1].
