Topcon影像全站仪在废弃采石场地形测量中的应用

Application of topcon imaging total station in topographic survey of abandoned quarry

近年来,废弃矿山生态环境问题越来越受到国家的重视,废弃矿山生态恢复逐渐发展为我国城市生态环境建设的重要内容之一,而区域地形测量则是生态恢复的基础。影像全站仪测量技术作为近年来发展的一种新兴地形测量技术,在废弃采石场地形测量中应用较为广泛。在介绍日本Topcon Corporation公司生产的影像全站仪测量技术原理的基础上,以实例实现地形测量及后期成图的全过程。实践证明,影像全站仪测量技术具有操作简单、测量速度快、精度高等优点,特别是影像全站仪测量过程中不需要用棱镜进行光线反射,极大地提高了地形测量的效率,同时对测量人员的安全性也有保障,适用于常规测量难以实现的困难立地地形测量。

In recent years, the ecological problem of abandoned quarry is increasingly noticed by national government. Ecological restoration of abandoned quarry has been an important zone of urban ecological construction in China. The regional topographic survey is the basis of ecological restoration. Imaging total station measurement as a new topographic survey technique developed in recent years has been widely used in the topographic survey of abandoned quarry. Based on the introduction of measurement principle of imaging total station made in Topcon Corporation in Japan, the entire process of topographic survey and post-mapping was practiced in an instance. Practice has proved that the imaging total station measurement technology have advantages with simple operation, high speed, and high precision. In particular, the non-prism measurement without a prism light reflection greatly improved the efficiency of the topographic survey, and protect the safety of the surveyors at the same time. This method can be applied to topographic survey in tough area where the conventional measurement is difficult to achieve.
