无反射棱镜全站仪在测量中的应用研究

摘要

Non prism total station is a station without prism as cooperative target can measure distance.It is a combination of free ran-ging technology with traditional reflection prism total station instrument, and the advantages are irreplaceable in common with total sta-tion.The use of non-reflecting prism is more convenient and faster, realized"the aim that is measured".Reflecting prism total sta-tion instrument has been widely used in the digital topographic map surveying and mapping, the determination of the object point accu-racy specification accuracy requirements.In this paper, the principle of non-prism measurement of this new technology achievement precision were systematically elaborated and summarized.%无反射棱镜全站仪是不用棱镜作为照射目标就可以进行测距的全站仪，是无反射棱镜测量距离技术与一般全站仪的融合，具有一般全站仪不能替代的优点。利用无反射棱镜可以方便、快捷地测量距离，实现了“即测即得”。已普遍应用于数字地形图测绘的此类全站仪，其所测定地物点的精度满足规范的要求，因此，对无反射棱镜测量这项新技术的工作原理、成果精度进行了系统的阐述与总结。
