摘　　要：CBMD是一款针对CB-3模拟磁照图进行数字化处理的软件,利用专业图像处理技术,对模拟磁照图进行数字化,由于模拟仪器调试及存放因素造成了图纸状况不尽相同,使用者在数字化处理过程中,根据不同的图,纸采用相应的方法进行处理,才能保证数字化结果精确度。本文就主要的几种影响处理精度的情况展开讨论,并提出具体的解决方法。CBMD is a computer program for digitizing the analog magnetic photographs produced by CB-3, using professional image processing techniques. Since the adjustment of analog instrument and storage condition is dissimilar, the photographs are of different status. Users should consider how to process the photographs to guarantee the digitization accuracy of magnetic photographs. In this paper, several factors that influence the process accuracy are discussed and resolutions are put forward.

关 键 词：CBMD 磁照图 精确数字化
