常规数码影像辅助的大比例尺数字测图

摘要

完整而准确地记录绘图信息,是目前主流数字测图作业模式中,最影响工作效率和劳动强度,并容易出现错漏的一项工作.针对这一问题,提出了一种借助常规数码影像记录相关信息辅助数字测图的方法.实验证明,该方法可以显著降低在地形复杂地区外业绘制草图和记录属性等的难度和工作量,有效减少内业编辑成图的错误.%It is a very critical step and the most influence on work efficiency and labor intensity to record the connection between measured points and the attribute of terrain in digital mapping with indoor and outdoor work separation form. And it also leads to error and pretermission easily. Aiming at this issue, an approach of large-scale digital mapping aided by common digital image was proposed in this paper. Experiments show that this approach can evidently reduce the difficulty and workload of outdoor work and decrease the error in indoor edit.
