Re: Suggestions for Given Capture Volume

<t>Vincent -- thanks for the help.<br/> <br/> We were hoping to use IR-LEDs to enable the cameras to see the points from far away. Is the limitation the software, or the visibility of the markers?<br/> <br/> Would there be any way to use enough cameras to "tile" the space, with several overlapping v...

Re: Problem with getting frames in C#

<t>Doug,<br/> <br/> Thank you so much. This has been a huge stoppage to my group.<br/> <br/> I had tried messing around with .Release() before, but couldn't get it to work.<br/> <br/> When I run the code above, I get a<br/> 'OptiTrack.NPCameraFrame' does not contain a definition for 'Release'<br/> <...

Anyone have a very basic C# example?

<t>Hi. I've checked out all the sample programs on the Optitrack page, and found them to be helpful. However, I'd like a really, really basic app in C# to just capture general frames and print out coords of objects detected (with one camera).<br/> <br/> Something like the C++ Win32 command line prog...

Re: Problem with getting frames in C#

<t>Birch,<br/> <br/> Thanks so much for the help. I'll try this.<br/> <br/> However, I'm a bit unclear how to determine that "there are no frames left." I'm sure this can easily be done in a while loop, but what would signal that there aren't any frames left? I already test to see if the frame retur...

Problem with getting frames in C#

<t>Hi. I'm using a single flex c120 and trying to develop a very basic app in C# to snap and image (and record coordinates of a detected point), move the camera, and do this again.<br/> <br/> I must be doing something conceptually wrong. If the object is in the camera view, my program will give me 4...

Mixed C120 and V100

<t>I had originally purchased 4 C120's for a custom-built application. I've just decided to buy the point-cloud toolkit for another application.<br/> <br/> Alas, I'd rather buy more V100's to boost my number of cameras. But the point-cloud toolkit doesn't support mixed cameras. This really stinks fo...

Re: Camera Lens calibration

<t>Birch,<br/> <br/> Thanks so much for the reply. I'll look at that INPVector3 interface.<br/> <br/> BTW... using Tsai's model, I got the following:<br/> <br/> f = 2.849240 [mm]<br/> kappa1 = 8.362079e-02 [1/mm^2]<br/> Cx = 182.793037, Cy = 133.506785 [pixels]<br/> <br/> Does that sound right?<br/>...

Re: Camera Lens calibration

<t>Scruff and Brich,<br/> <br/> Thanks for posting this. I'm also trying to calibrate my Flex 120 camera.<br/> <br/> I'm using the Roger Tsai method, and need the intrinsic camera params. I'm assuming using 2.2 mm by 1.8 mm for the image sensor and 355x288 will work.<br/> <br/> I'm confused, though,...
