Re: Using CameraSDK with Visual Basic

[quote=MikeInCinci]Does the "tracking tools" support 2D tracking of a single dot and can it be interfaced using VB6? [/quote] Tracking Tools can output marker coordinates via VRPN (network stream). This could easily be received by any VB6 app (using Winsock OCX for example). You could also try to co...

Re: Support in SDK for lens and projection distortions

[quote=NaturalPoint - Doug] The OpenCV approach should work for you as well. They have a good way of doing it and their model is similar to ours so I would expect good results using that approach. [/quote] Well, just to let you know what I'm doing: I've got a test-app which starts with grid-points o...

Re: Support in SDK for lens and projection distortions

<t>Well, I'm doing my own intrinsic calibration, and then I'm currently using OpenCV undistort functions as well as a custom thing -- but I'm not happy with the OpenCV function. <br/> <br/> So if you've got this function inside the camera SDK, I'll happily give Core::Predistort2DPoint() a try. Is th...

Re: Support in SDK for lens and projection distortions

<t>Seth, could you elaborate on the exact functions to use from the SDK? I've got V100R2 cams with 3.5mm lenses...<br/> <br/> kb_kat, would you be so kind and post your results of the lense distortion you measured? I myself get distortions of between 8 and 12 pixels in the corners of the image (as I...

Re: Pushing MJPEG frame to AVI file without decompression

Hey Gaspard, a search for "compress" in the Camera SDK header files reveals this: Frame* IncomingCompressedFrame(CompressedFrame *frame, bool DataPath=true); in file camerarev11.h . Although this line (same file) int HardwareFrameRate() { return 250; } suggests it's not a V120:SLIM camera. Anyway, j...

<t>[quote=NaturalPoint - Doug]Hey LinusA,<br/> Does that help?<br/> [/quote]<br/> It did indeed, thank you so much! You saved me the hustle to implement my own frame-getter-thread.<br/> <br/> It's all very obvious what you posted -- it makes perfect sense. I don't really get why I didn't come up wit...

Re: Camera->GetFrame(), GetLatestFrame(), and frame queues

The problem is more serious than I thought :-( Even if I call FrameGroup->GetFrame() as quickly as I can, a "backlog" inside the frame-queue builds up. This causes a significant lag with my application, the markers are visible "behind in time". I was very glad that I had solved this problem by using...

Re: Camera->GetFrame(), GetLatestFrame(), and frame queues

<t>I just noticed: When using cModuleSync with FrameGroups, there is neither a function called GetLatestFrameGroup, or GetLatestFrame within the FrameGroup. The thing is: I started to like GetLatestFrame, as it would get me the newestup2date frame, even in situations were I can't keep up (due too st...

Re: camera SDK latency with TrackIR5

I'm sorry if this question sounds too obvious, but did you install the latest graphics drivers? I forgot that once, and OpenGL applications were very slow.
