Transcript

  • 1. ifgicopter – Microcopter as a sensor platform for environmental monitoring Matthes Rieke, Christian Knoth ITC Visit @ ifgi, Münster, 13.09.2010 http://swsl.uni-muenster.de/research/ifgicopter 1
  • 2. Motivation ● Set of problems ● Creation of orthophotos of small areas of interest – financial and logistical complex venture – areas of interest which are hard to reach ● Measurements of climate phenomena – are not available in the desired dose or are out of date – Hard to reach → http://swsl.uni-muenster.de/research/ifgicopter 2
  • 3. Motivation ● Aims of the project 1.Individual creation of (infrared) orthophotos of small areas of interest – sustainable environmental monitoring ● vegetation assesement ● terrain acquisition ● Hi-res images → temporary change of unreachable areas of interest 2.Highly flexible usage of a flying sensor platform to gather climate phenomena measurements – No long preliminary work needed http://swsl.uni-muenster.de/research/ifgicopter 3
  • 4. Team and fields of work ● Fields of work ● Planning software (Geoinformatics) ● Communication framework (Geoinformatics) ● Creation of orthophotos (Geography) ● Analysation of climate phenomena (landscape economy) ● DGPS services (Geoinformatics) http://swsl.uni-muenster.de/research/ifgicopter 4
  • 5. The ifgicopter ● Basis is a building kit by www.mikrokopter.de ● GPS modules already integrated http://swsl.uni-muenster.de/research/ifgicopter 5
  • 6. Communication ● Communication in real-time ● Copter uses a Wi232 module to periodly send data (HF at 868 Mhz → no license needed in germany) ● Gathering of GPS position and many other useful data ● Uplink ● Send GPS waypoints to the copter http://swsl.uni-muenster.de/research/ifgicopter 6
  • 7. Application 1: Orthophotography ● First application – Creation of Orthophotos ● Flightroute planning software http://swsl.uni-muenster.de/research/ifgicopter 7
  • 8. Application 1: Orthophotography ● First application – Creation of Orthophotos http://swsl.uni-muenster.de/research/ifgicopter 8
  • 9. Application 1: Orthophotography ● Photographs need to overlap about 60% with their neighbours → automatic calculation of waypoints following this requirement ● Planning software is capable of creating a flight route which covers a user-defined area of interest (bounding box, polygon, etc.) http://swsl.uni-muenster.de/research/ifgicopter 9
  • 10. Application 1: Orthophotography ● The camera: Panasonic LUMIX LX3 – UV+VIS+IR ● Internal band-elimination filter removed → photographs in VIS and NIR possible with an additional filter source: http://www.digitalkamera.de http://swsl.uni-muenster.de/research/ifgicopter 10
  • 11. Application 1: Orthophotography ● Example of infrared composite source: http://www.maxmax.com http://swsl.uni-muenster.de/research/ifgicopter 11
  • 12. Application 1: Orthophotography ● Classification of a rapeseed field http://swsl.uni-muenster.de/research/ifgicopter 12
  • 13. Application 1: Orthophotography ● Classification of a rapeseed field http://swsl.uni-muenster.de/research/ifgicopter 13
  • 14. Application 2: real-time data gathering ● Second application – real-time data gathering ● Two-tier architecture – Transmission of measurements from copter to a groundstation – Transformation into standardized data formats (OGC: Observation & Measurements) and integration into the Sensor Web http://swsl.uni-muenster.de/research/ifgicopter 14
  • 15. Application 2: real-time data gathering ● Realization using a two-tier framework – Input in proprietary formats – Output as interoperable data ● Why framework? ● Not restricted to ifgicopter platform → other sensor platforms easily integrable ● Connection to web services made simple http://swsl.uni-muenster.de/research/ifgicopter 15
  • 16. Application 2: real-time data gathering ● Architecture http://swsl.uni-muenster.de/research/ifgicopter 16
  • 17. Future work ● Visualization ● Additional sensors ● Fine dust ● LIDAR (laser scanning) ● Gas sensors ● Digital elevation models ● Autonomic flight (security and surveillance) http://swsl.uni-muenster.de/research/ifgicopter 17
  • 18. Video footage ● Video of a waypoint flight http://swsl.uni-muenster.de/research/ifgicopter 18
