基于形态学走廊环境门牌号的识别

Doorplate Identification for Mobile Robot in Hallway Based on Morphological

提出了一种未知走廊环境下的门牌号定位识别方法。为了识别走廊环境中的门牌号码,机器人在不同光照环境下拍摄门图像,利用Robert边缘检测、形态学运算相结合的方法定位门牌号图像的位置,再经过水平和垂直投影法,倾斜校正等操作分割得到门牌号图像,最后运用模式识别识别出门牌号码。实验结果证明此方法可以准确地识别出门牌号码,为视觉导航提供环境信息。

A new method of locating and identifying the doorplates in unknown hallway environment is proposed. To de- tect the doorplate, mobile robot took the door images in different illumination environment, then, the algorithm robert edge detection and morphological operation were used to locate the position of doorplate image, the doorplate was obtained by image segmentation technology such as horizontal and vertical projection, slanting correction, and the doorplate could be identified by pattern recognition. The experimental results prove that the methods can identify the doorplate accurately, which can pro- vide environment information for vision navigation.
