George- Alexis Ioannakis
:: Short bio ::
George Alexis Ioannakis is pursuing for his Ph.D. degree at the dept. of Electrical and Computer Engineering, Democritus University of Thrace, Greece. He received his MEng Diploma at the dept. of Rural and Surveying Engineering, Aristotle University of Thessaloniki, Greece. Since 2013 he is working as a Research Assistant at the dept. of Electrical and Computer Engineering, Democritus University of Thrace and the Athena Research and Innovation Centre, Multimedia dept. Among his research interests are the 3d mesh processing, 3d object retrieval, photogrammetry, image processing, machine learning and rc multicopter construction/programming.
At this time of my life, I am working as a Research Assistant at the Democritus University of Thrace on the project 3DOR-Thalis(775). Among others we develop RETRIEVAL, an on-line benchmarking tool for retrieval methods. In simple words everyone can upload his retrieval results and the tool will evaluate all the metrics that exist in literature. RETRIEVAL is temporarily hosted under the url: retrieval.ceti.gr.

DIY H-shape quadcopter
The idea of building a quadcopter was conceived during the plenty leisure time I had while serving the military :-). The plan was to create something from scratch that could fly stable and shoot image sequences for photogrammetry purposes and just fun. The result is satisfying, but it demands very high steering skills. In the mean time steering algorithms have really evolved, something that made it easier for -amateur level- people to fly.
The quadcopter's frame is completely build of wood(it was chosen due to its tiny weight) and its frame shape is an H, because it is more suitable for mounting all the necessary parts (e.g. motors, flightcontroller, battery e.t.c.) while keeping it "in balance".
The quadcopter is equipped with four brushless motors of 930kV and 25A brushless speedcontrollers. The flightcontroller is kk2.0. Finally the quadcopter is powered by a 2200mAh 3S 25C Lipo Pack.
The receiver is turnigy 9x+ 2.4 GHz 8 Channel v.2.
The total amount of money spent is 190 euros.
