摘　　要：无棱镜电子平板作业模式已成为数字测图的主要方法。然而,在无棱镜测距的实际使用过程中,经常会出现测的不准、甚至测错的情况。现将结合多年数字测图过程中的经验教训,重点梳理无棱镜使用过程中应当把握的精度问题,归纳了上中下三次观测来测量平面位置,左中右三次观测来测量高程、加点验线法、图形校核等解决方法,达到了无棱镜功能在电子平板测图中发挥最大作用的目的。A operating mode of reflectorless total station and electronic plane-tablet has become the main method of digital mapping. However, in the actual use of Reflectorless functions, there are often situations where the measure- ment is not accurate or even wrong. Based on the the experience and lessons in the process of digital mapping for many years, we will focus on sorting out the accuracy problems that should be grasped during the use of reflectorless total station, and sum up the position of the plane in the upper and lower three observations, the method of measuring elevation three times in left, middle and right, adding point line checking, graphic checking, etc. achieves the purpose of maximum effect without prism function.
