Abstract

La presente descripción se refiere a un método y a un dispositivo para detectar una línea recta, que pertenece al campo de procesamiento de imagen; el método incluye: adquirir un conjunto de características de histograma de gradiente de cada uno de respectivos puntos de pixel en una imagen, en donde el conjunto de características de histograma de gradiente está configurado para reflejar características de línea recta de un área local donde se sitúa el punto de píxel; determinar por lo menos una dirección candidata de una línea recta a ser detectada según los conjuntos de características de histograma de gradiente de los respectivos puntos de píxel; y determinar una dirección precisa y una posición precisa de la línea recta a ser detectada según la por lo menos una dirección candidata; la revelación presente resuelve el problema en la técnica relacionada de que el método para detectar la línea recta puede causar que la línea recta se rompa y el resultado de detección sea inexacto cuando la fuerza de orilla es débil o hay interferencias de ruido existentes; además, el método para detectar la línea recta proporcionada por la presente descripción no usa la transformada de Hough ni binariza la imagen, de manera que las influencias de los errores causados por la binarización se evitan lo suficiente, y aumenta la precisión de la detección de la línea recta.
