Efficient Design of Measurement Assistance Systems for Robotic Total Stations using Custom Simulation with Unity3D, by Christoph Klug, VRVis & Augmented Reality Instructions by Peter Mohr-Ziak, VRVis
Talk 1: Efficient Design of Measurement Assistance Systems for Robotic Total Stations using Custom Simulation with Unity3D, by Christoph Klug, VRVis
Abstract: Research on interactive algorithms and workflows for robotic total stations (RTS) usually require hardware-in-the-loop approaches. However, this is obstructive and time-consuming for many reasons. We developed a complete system to extract and simulate geometric properties of an RTS. Our concept allows efficient design and test of RTS interactions with Unity3D, and verification with physical setups without software modifications. In this talk, we will discuss: 1. a method to extract a geometric simulation model using the RTS driver API only, 2. the analysis of the model-driver-discrepancy, and 3. an a-priori uncertainty characterization of simulation setups according to GUM, the Guide to the Expression of Uncertainty. Furthermore, we will briefly discuss two showcases for RTS assistance systems: 1) An assistance system for manual measurement of Manhattan corners. 2) An assistance system for semi-automatic RTS-registration using Manhattan corners.
Short Bio: Christoph Klug received the M.S. degree in Telematics from the Technical University of Graz (2012). After suspending his university career to work in the Automotive industry as an embedded software designer for several years, he is now working as a research assistant at the Virtual Reality and Visualisation Research Centre GmbH (VRVis) in cooperation with the Technical University of Graz, where he is finishing his Ph.D. degree in computer sciences. He is currently putting all his energy in enhancing workflows and algorithms for robotic total stations using Computer Vision methods with special regard to usability and accuracy. Further research interests lie in Computer Vision and Graphics, geometric modeling and human computer interaction.
Talk 2: Augmented Reality Instructions by Peter Mohr-Ziak, VRVis
Abstract: Augmented reality (AR) has been demonstrated to be an effective way of presenting tutorials and handbooks. However, creating 3D content for AR is costly and requires specially trained authors. Our research aims to accelerate the authoring process of AR instructions by interactively retargeting conventional, two-dimensional content into three-dimensional AR tutorials. In addition, we present visualization and rendering techniques tailored for AR instructions, as well as a novel interaction method for head-mounted displays.
Short Bio: Peter Mohr is currently working as a researcher at the VRVis Forschungs GmbH and the Institute of Computer Graphics and Vision on the University of Technology Graz (TU-Graz). He studied telematics at TU-Graz. At the moment Peter is working in the field of Augmented Reality (AR) with special regard to authoring instructions for AR under the supervision of Prof. Dieter Schmalstieg and Prof. Denis Kalkofen. The research interests of Peter lie in AR visualization, content generation for AR and head mounted displays (HMDs). In his spare time, he enjoys photography and drone flying.
