  1. 3D Flight Path Tracking of Butterflies by Image Processingtoinvestigatemovement in responsetoconditionandenvironment Oliver Mitesser, ÁdámKőrösi, Thomas Hovestadt, Peter Möhringer Gunther Bohn, University of Applied Sciences Würzburg/Schweinfurt Germany Bio Zentrum der UniversitätWürzburg XXXII. International Conference Science in Practice, Osijek 2014

  2. The problem “there is no information available on navigation abilities of butterflies in small-scale foraging movement and whether and how they might use spatial information Bio-Zentrum University of Würzburg XXXII. International Conference Science in Practice, Osijek 2014

  3. I. Introduction • Goal of the project: • ► Make behaviouralexperiments on butterflies • ► Explore sensory abilities • ► Identify role of internal status like hunger-level, egg-load etc • ► Explore memory and learning effects • ► Butterflies either memorize or mark host plants visited • ► Explore inference and anticipation XXXII. International Conference Science in Practice, Osijek 2014

  4. II. Flight cage and cameras: ► Near natural environment in a flight cage ► Cameras record movements of the butterflies XXXII. International Conference Science in Practice, Osijek 2014

  5. The test flight cage (8m x 8m x 3m) XXXII. International Conference Science in Practice, Osijek 2014

  6. S3D-HD cameras mounted on top of the flight cage XXXII. International Conference Science in Practice, Osijek 2014

  12. III. Image anddataprocessing ► Image processing detects butterflies and determines flight trajectories ► Statistics give insight into the behaviour of the butterflies ► Identify decision rules ► Create and improve movement model XXXII. International Conference Science in Practice, Osijek 2014

  13. S3D camera object behind the screen screen position object in front of screen Disparity related to position of object XXXII. International Conference Science in Practice, Osijek 2014

  14. Disparity in front and behind the screen XXXII. International Conference Science in Practice, Osijek 2014

  15. Result of a 3D analysis OMNITECOTR 1001 TV test system XXXII. International Conference Science in Practice, Osijek 2014

  16. IV. First results Example video XXXII. International Conference Science in Practice, Osijek 2014

  17. Example of data management and processing part of x-y trajectory XXXII. International Conference Science in Practice, Osijek 2014

  18. V. Conclusion • Already promising first results: • ► Test flight cage and consumer cameras show viability • ►Image processing is still to be developed • ► Explore memory and learning effects (in the future) • ► Explore inference and anticipation (in the future) • ►Define and improve movement model (in the future) • ►Compare model to measured trajectories (in the future) XXXII. International Conference Science in Practice, Osijek 2014
