摘要
历史资料数字化存档可以很好保护历史地形图资料,但处理过程面临着数据量大、不易校正、难拼接等问题。我院采用新的方法,将历史资料扫描后,利用有限元方法进行纠正,批量裁剪为统一大小,利用MrSID方法压缩拼接,很好地解决了这一问题。
It will do good to the protection of historical topographic map for the historical date to be stored in digital form,but there are still problems such as large amount of data,unease to correct and mosaic.We chose a new kind of method to deal with it.After scanning,finite element method was chosen to carry out correction,images size was made uniform after batch processing and were compressed by MRSID method.We achieved very good results.
