动态测量技术精度检测系统设计

随着动态测量技术的快速发展,对其精度鉴定的需求也愈发迫切。目前,对于动态测量技术的检测仍旧存在很多技术瓶颈,甚至对于一些中、高动态测量设备还无法提供有效的检测手段。本文中提出了一种基于旋转平台和光电传感器的动态检测原理、设计方案和检测流程,完成了原理样机的研制,并进行了大量的实验测试和验证。实验表明,对于0.88cm/s-3.54cm/s的低动态的全站仪动态跟踪测量,该系统可以实现0.4-0.6mm精度的检测,对于0.98cm/s-6.28m/s的中、低动态的GPS动态测量则能够实现3-10mm的检测精度。

The design of precision inspection system for dynamic surveying technology

With the rapid development of dynamic surveying technology, the necessity of precision evaluation becomes more and more urgent. It is now still many technical bottlenecks in dynamic surveying technology, there is even no inspection solution available for some equipments in medium and high velocities. In this paper, it proposes a dynamic inspection principle, its design program and the inspection process based on the rotation platform and the photoelectric sensor. Then the sample equipment is accomplished on which many experiments and proving activities are carried out. According to the experiments, the inspection precision for total station dynamic surveying ranges from 0.4mm to 0.6mm under low velocity condition(lower than 3cm/s),while the precision for GPS dynamic surveying is 3mm-10mm under low and medium velocity conditions(lower than 6m/s).
