TT_Update gives only 50 fps

Post by jarmokauko » Mon Jan 10, 2011 8:40 am

Hi,

I'm running the TrackingTools 2.3.0 sample application, and the frame rate seems to be limited to 50 fps. For example, if the main loop runs every 5 ms, in 1 second TT_Update returns 50 x NPRESULT_SUCCESS and 150 x NPRESULT_NOFRAMEAVAILABLE.

The Tracking Tools GUI shows 100 fps for camera frame rate. I have 6 FLEX:V100R2 cameras, connected through 2 OptiHubs.

Thanks,
-Jarmo

PS. Does the forum have search functionality?

Hey Jarmo,

Can you try this and see if it solves your problem. This will delay loading your project until all the cameras have fully intialized:

Code: Select all

    TT_Initialize();

    while(TT_CameraCount()==0)
    {
        TT_Update();
        Sleep(5);
    }

    TT_LoadProject(...);
