VRsurv

Description

Abstract (English)

Today's typical surveying tasks, like staking out or monitoring, take place in a dynamic and fully 3D environment with many dependencies on other objects. Obstructions and disturbances of the line of sights must be foreseen often at a very early stage of a project. Also, the high precision of modern surveying instruments requires a detailed evaluation of systematic effects to fulfil nowadays accuracy demands.

In order to compete with these requirements, the planning environment for modern geodetic network design needs to be in 3D and object orientated to cover the relations and dependencies between relevant object groups within the monitoring scenario. Moreover, it should be capable of processing meshed reality capture data sets and design models from architects to serve as a basis for feasibility studies of the concept.

Such a geodetic 3D planning tool is realized with the experimental software VRsurv at the Institute of Engineering Geodesy and Measurement Systems (IGMS) of Graz University of Technology. Fully operational virtual surveying equipment can be placed in an interactive 3D environment. Therefore, a modelled total station can turn and steer onto prisms and the line of sight is automatically checked for obstructions, optimal prism orientation or automatic aiming issues.
