摘要
全站仪是在工程测量中广泛应用的高精度仪器,对于测角和测边具有精度高、速度快的优点。文章首先介绍了全站仪悬高测量的基本原理和在工程中的应用;然后针对在实际应用中,必须要将反射棱镜恰好安置在被测目标点的天底以便获得准确结果这一硬性条件进行了讨论,并提出了一种有效的改进方法来解决这一问题。理论结果表明本文提出的方法能够有效解决反射棱镜放置问题,因此能更好地发挥全站仪的先进功能,为实际生产服务。
Total station is a widely used apparatus in engineering survey,which has the advantages of high accuracy and high speed in terms of angle and distance measurement.In the present paper,the fundamental rationale and application of suspension survey with total station apparatus in engineering are introduced firstly.In practice,that the reflecting prism should be laid rightly in the nadir of the target to obtain accurate results is a strict constraint.An effective improved method is then proposed to overcome this constraint.The theoretical result shows that the method proposed effectively can solve the problem of reflecting prism placement.Therefore,the advanced functions of the total station apparatus can be more efficiently exploited in engineering operations.
