摘　　要：目前,世界上极少数的公司垄断了数字水准仪的生产,他们的专利保护主要集中在电子读数原理和标尺编码结构上。本文在此背景下,提出了一种新的基于二进制编码的标尺编码方案。该方案将使用的刻度标尺横线进行二进制编码,水准仪部分采用面阵CCD采集标尺图像,利用快速数字图像处理算法进行水平中心定位读数。理论分析和实验表明,该设计具有可行性,在标尺不同位置和椒盐噪声点数小于60 K的时候有着100%的识别率。At present,a handful of companies in the world monopolize the production of digital level,and the current patent protection of digital level is mainly concentrated in the electronic reading principle and staff coding structure.digital level,we must put forward a set of new methods.In this paper,a new coding scheme based on binary coding is proposed which using the horizontal line on staff for binary coding,matrix CCD image to capture the staff image and fast digital image processing algorithm for horizontal center positioning readings.Theoretical analysis and simulation show that the design is feasible,the recognition rate is 100%in different staff locations and noise points less than 60 K.
