基于自适应特征提取的数显仪表识别系统
Digital-display instrument recognition system based on adaptive feature extraction
摘要
Abstract
In order to make the digital-display instrument adapt to various outdoor environments,an instrument′s automatic recognition system adaptive to various illuminations is established. According to the features that the color of the bright area of the digital-display instrument image is almost red and the color of the dark area is partial to gray,the color space filtering method based on RGB is designed to reserve the luminance information of the bright area better. The improved Otsu method is proposed to realize the adaptive extraction of image characters of the digital-display instrument. The threading recognition method is used to realize the automatic recognition of the digital-display instrument according to the digital feature information of digital-display instrument. The actual measured results of massive experiments show that the adaptive feature extraction algorithm has strong adaptability to the instrument images taken in different imaging angles and different illumination environments,and can get the identification accuracy of 95% when it is applied to the automatic recognition system of digital-display instrument;its average running time is 1.136 second.关键词
