Hi Sergey, I have a reasonable amount of experience with motion tracking. From my robotics projects and, more recently, with my project on gait analysis. I was a little overwhelmed with the project description though. Were the individual projects mentioned intended as one large project or as suggestions for separate projects? I have a little experience relating to the lens estimation and variable focal length projects and a considerable amount of experience with multi-camera reconstructions, but implementing all eight projects listed seems like a lot in a summer.
My own suggestions for this project are based on the needs I've felt while working on my current assignment. The lab I'm volunteering at uses 8 cameras spaced around a room to determine the x, y and z coordinates of 15 LEDs attached to different points of a subjects legs. The data is stored as the subject moves and my program recreates the motion on my screen. It also calculates the internal forces involved and re-simulates the motion, given certain additional criteria. I'm presenting my software on Monday to the department, and I can send a youtube link with my application. The method of reconstructing the motion was pretty basic. The cameras generated the coordinates in the form: <frame number> <LED/reference point number> <x> <y> <z> which seemed like a pretty obvious format to me. I was surprised to find that I couldn't find a software that directly took data of this form or any similar form and reconstructed the motion. If one could design a 3d object (even a humanoid) and specifically assign the reference points (say a marker on your right wrist) to distinct points on the objects (the right wrist of the humanoid) in an open source application, I think it would save on a lot of tedious coding and have numerous applications (maybe even for virtual games). I'm not sure if I've described this clearly. Please let me know if it needs further explanation or if you think it could be incorporated into the motion tracking project. Thanks.
