2D to 3D

Hello Doug , I am currently working on a project and have used tracker to do the 2D video analysis. My next step in the project is to develop or start working on ideas to make 2D analysis into a 3D video analysis.I have multiple cameras and the resources.U hope to use tracker for the same.I am fine with the learning curve being steep and long.I just need some ideas and advice on the same. Thank you, Vijay Padmanabhan
I have never done a 3D analysis so cannot advise except to note that the ability to synchronize the cameras (so both shutters operate at exactly the same time) would make it much easier. If you do this, and match the calibrations, I think combining the data in a spreadsheet should be straightforward.
I too would like to hear from someone who has done this. Anybody?? Doug

I've used Tracker only for some 2D analysis. As a biomechanics hobbyist, I've done sports movement 2D and 3D analysis for personal interest using these software programs: - Ehuman by HMA Technology. This is an exceptionally good program that was priced very low, but unfortunately, is no longer available to the public. The prof at York University in Canada who developed the program seems to now be retired. - KA 2D/3D (See http://userwww.sfsu.edu/biomech/ForFaculty/ka2d_3d.htm).

Setting up biomechanical projects for 3D analysis requires many detailed considerations as described in Chapter 2 of this book: http://www.sportsbiomech.com/Books/Biomechanics%20of%20movement.pdf
