摘　　要：计算机联锁自动化测试能够节省软件测试阶段的人力成本,而实现自动化测试的前提是需要提供可靠的站场信息。文章以上位机界面显示规范为主要技术文件,提出一种基于计算机视觉图像分析与文字识别技术提取计算机联锁软件上位机界面信息的方法,该方法通过挖掘可量化的信号设备和功能按钮图元特征,以及二者在界面内名称的字符特征,实现基于上位机界面截图的站场信息提取功能。以中国铁路广州局集团有限公司连江口车站计算机联锁软件为例,验证了该方法的可行性,为自动提取站场信息提供了新思路。Computer interlocking automatic testing can save the labor cost in the phase of software testing,while providing reliable interface layout data is the premise of realizing automatic testing.According to the upper computer interface display specification,this paper proposed a method for extracting information from the upper computer interface of computer interlocking software based on computer vision image analysis and text recognition technology.This method implemented station information extraction based on upper computer interface screenshots by mining quantifiable features of signal devices and function button entities,as well as the character features of their names in the interface.Taking the computer interlocking software of Lianjiangkou Station of China Railway Guangzhou Group Co.Ltd.as an example,the feasibility of this method is verified,which provides a new idea for automatic extraction of station yard information.
