Extract camera parameters from recording

Hi, we are doing research on calibration and triangulation algorithms, and I would like to extract at least the camera parameters from a recording I did in Motive:Tracker. I am able to extract the information when the actual cameras are connected, but I am away from the labo for a week, and I don't ...

NatNet client memory management

<t>Hi,<br/> <br/> I am using the NatNet client class in C++, and I was wondering if I had to do any memory cleanup. The samples doesn't seem to clean up any memory. The functions I am talking about:<br/> <br/> SendMessageAndWait writes to a void* message. How is that memory managed?<br/> <br/> GetDa...

Re: Calibration using the SDK

OK, thanks for the information. We will keep using the application for calibration purposes then.

Re: Camera positional information

Thanks a lot! I will use the SDK to save the information then. Is this information by any chance also available in the Tracking Tools GUI?

Calibration using the SDK

<t>Hi,<br/> <br/> We have a very specific setup and use custom software to do motion analysis, using only the positional info of unidentified markers output by Tracking Tools.<br/> <br/> The only thing we have to use the actual Tracking Tools GUI for is the calibration process. Are there any plans t...

Camera positional information

<t>Hi,<br/> <br/> We are doing experiments on positioning the six cameras we use for our specific setup, and want to save/report the position and rotation information (so the extrinsic parameters) of the cameras, so we can reproduce the setup later on.<br/> <br/> Is this possible, using the Tracking...

Re: Active LED "lens" shape

Allright, that was the answer I was looking for. I will find a way to shave the material as ball-shaped as possible.

Thanks

Re: Active LED "lens" shape

<t>I'm not sure if I made myself clear in my post: the part we put onto the led is not round: it is a cylinder shape, cut from a stick from a glue gun. The material itself seems perfect for the job, but I was wondering if the cylindrical shape will be a problem for accuracy (so whether the centroid ...

Active LED "lens" shape

<t>Hi all,<br/> <br/> We are using Tracking Tools to create a specific motion capturing and analysis setup for bicycles. Because of the reflective materials used on modern bikes, we quickly came to the conclusion that passive markers was not the way to go. So we are developing a setup using active I...

Re: Tracking individual points

<t>Nevermind about the ground plane issue. Turns out there was a ghost marker that I accidentally selected in stead of a real ground marker. The axes are correctly setup now.<br/> <br/> I also implemented a very rudimentary algorithm to trace the motion of a single marker by just searching for the n...
