Re: GetDataDescriptions returns 0

I am testing with 2.5.0. I was testing with my own application, but I just checked the WinFormTestApp with unicast and it also appears to fail with "Unable to retrieve DataDescriptions"
Thanks!

GetDataDescriptions returns 0

Hello, I am trying to get the list of trackables from the server via GetDataDescriptions call but nothing appears to happen. The call returns 0 and the pointer passed in does not change. In Motive I have 1 rigid body and rigid body streaming is enabled. The client has been initialized and I am able ...

Pre-alpha Python wrapper for C++ Camera SDK

Ever wished you could use the Camera SDK from a Python application? Well, I did, so I've started development on a Python wrapper. You can download it from my lab's Github repository here: https://github.com/OlinRoboticsAndBioinspiration/pycamera The wrapper uses a language called Cython from which C...

<r>I am working on Python wrappers for the Motive API (but the .h and .dll files are still named TrackingTools - <E>:cool:</E>). <br/> <br/> It seems Motive is now using Intel's OpenMP library (libiomp5mt.lib), but the I also have the Enthought Python Distribution installed and it includes a version...

Re: Handling continuous rotations (> 180 deg.)

As it turns out, I decided to process the data in Python, and the NumPy package has a very nice function called "unwrap" that does exactly what I needed, giving a true integrated estimate of angles.

Handling continuous rotations (> 180 deg.)

<t>I'm trying to perform motion capture on a small planar double pendulum with a 4 camera setup of s250e cameras. I'm able to make trackables from each of the links of the pendulum and get the data out of the Tracking Tools .csv file just fine. <br/> <br/> However, I've noticed that for rotations gr...

Re: Max samples for calibration?

Mike,

Thanks for the clarification. I've generally been very happy with the quality of our calibrations, so far, so I don't see it being an issue.

Max samples for calibration?

<t>I've been performing calibrations for my OptiTrack system that consists of 6 s250e cameras and even with "Apply and refine" it appears to only be using about 100 samples to do the calibration. Assuming more data would generate a more accurate calibration, is there any way to get Tracking Tools to...
