Workshop "Ubiquitous Tracking", Salzburg 06-08 Feb 2004

protocol 08 Feb 2004: internal discussion about diploma theses


Dagmar Beyer, Daniel Pustka, Franz Strasser

thematical separation of the diploma theses

  • Daniel: application for calibration, fusion components
  • Franz: connecting subgraphs, independent from calibration and data flow graphs
  • Dagmar: path search on spatial realtionship graphs
    constistent IDs for objects, no consideration of anonymous objects


  • Franz - Dagmar: both must work on the spatial relationship graphs.
    find a suitable representation in DWARF
  • Daniel - Franz/Dagmar: calibration needs at least two different paths between two objects.
    could be selected manually for testing

further considerations

  • Franz:
    • Mapping the topology of the Spatial Relationship Graph and the logical topology of the underlying network
    • Connecting different logical network subsystems
    • Connecting two differnt SR-Graphs (SR1, SR2)
      observe spatial relation between nodes in SR1 and SR2 in order to find connecting edges between SR1 and SR2
    • classification of new objects or anonymous measurements:
      1. anonymous object in SR1: new object or anonymous object (measurement of a motion detector for example)
      2. already identified object in SR2
      3. same motion modell, same position: insert an ID-edge between them

  • Dagmar:
    • evaluation of the error function
    • inferred attributes for Data Flow Components such as Interpolation Component, etc
    • implementation and anlaysis of different path-search algorithms for different classes of error functions
      • complexity analysis
      • experimental results in simulation environment


  • list requirements for the diploma theses
  • set focus on main problems
  • optimisation only in those parts
  • priorisation of tasks/implementations
  • find representation of the spatial relationship graph in DWARF
  • definition of error function and attribute mapping
  • how far is fusion (loosely coupled) part of the Ubitrack system?
