Single/multiple Point Tracking

[Queeny]

Hello,

I am new to the optitrack system and I have a few questions about it. I am using the a optitrack flex:c120 camera, the optitrack SDK and the API documentation to try and acheive multiple point tracking. Of course, I will first try to acheive single point tracking, and then move on to multiple point tracking.

How can I acheive single point tracking with what I have?
So far, I managed to ouput the object count from every frame. And I think that I should use the getObjectData method, but I do not understand it enough to use it.

Is there a single point tracking sample?
In previous posts, I read that there is a single point tracking sample, but I do not know which sample that is; I already compiled the grayscale and the command line sample.

Is there a command for beginning tracking? or does the camera automatically rank the objects and track the highest ranked object all the time?

How do I decide which camera options to change so that I could track the object that I need? is it just trial and error?

Also, is there a thorough example on how to use the smoothing interface?
I understand how to use the INPObject, INPCameraFrame, INPCamera, and INPCameraCollection interfaces...is smoothing different? it's different to me, because it's an action, not a physical thing...while, object, frame, camera and camera collection are physical things.

Thanks for your help.

The C++ VC8/2005 Sample for the OptiTrack SDK should include example code for how to read the highest ranked object in a frame as well as show basic information about smoothing. Our recommendation is for you to experiment with the settings until you find something that works best for you.

You also have the option of reading all of the markers for a frame and performing your own tracking and ranking on them if the built in features aren't what you are looking for.

Hi kweenee,

I'm new to this topic. Could you please tell me where you got the sample code for single/multiple point tracking?


Thanks in advance.
