Re: Compatible Visual Studio versions
Just to be clear: Yes, the camera SDK is compatible with VS2008. I myself am using it with OpenCV 2.2 and Qt 4.7.3 on WinXP and Win7 (both 32bit) with VS2008, and with VS2010 (and OpenCV and Qt) on Win7 64bit.

Re: Camera images to OpenCV
<r>I've been compiling my project on three machines: Visual Studio 2008 on WinXP SP3 32bit, VS 2008 in Win7 32bit, and VS 2010 Win7 64bit.<br/> <br/> In all cases I'm using Camera SDK 1.0 (but this doesn't matter, all 1.x versions work), OpenCV 2.2 with a custom patch, and Qt 4.7.3. I always compile...

Re: Camera images to OpenCV
[quote=malboro]Hi this is the code i am trying Thanks to LinusA but i only get gray image in the imshow window. I use a Trackir 4 camera, any idea? Thank you [/quote] You're using a single-channel cv::Mat, which is a gray image. I wrote above how to retrieve the data so you can do "color proces...

Re: Detecting red laser beam by using Optitrack V100:R2
<t>Oh, and, are you sure it has to be a laser beam (I mean, you wouldn't see the beam in air anyway, only the spot where it hits the cam)? Are you sure you can't just use regular retroreflective markers? I mean, that's the whole point of V100:R2 cams. Otherwise "regular" cams would do, especially if...

Re: Detecting red laser beam by using Optitrack V100:R2
<t>I guess you don't have V100:R2 cams with FS (filter switcher) technology? In that case you could just disable the IR band pass filter.<br/> <br/> Otherwise yes, you'd have to buy a an IR laser with about 800nm wavelength. They can be particulary dangerouse, as you cannot see the beam, while it ca...

Timestamps etc. and time of actual "snapshot"?
Hi, I'm trying to figure the time delay between the actual "snapshot" (i.e. the precise moment of exposure) of synced V100R2 cams, and the time I'm actually processing the marker data in my application. I am successfully reading timestamps of individual frames (CameraLibrary::Frame). To wo...

Re: About CModuleVectorProcessing Class
Doug, I guess what symparobofr is trying to say: Given this marker base http://www.naturalpoint.com/optitrack/static/img/markerBaseRigidBody.png , what are the real 3D positions of the marker centers, when you put markers on the studs? I.e. do you have the exact data you produce this marker base fro...

Re: Support in SDK for lens and projection distortions
<r>[quote=kb_kat]Hello, LinusA.<br/> Sorry for the late response to your request. The idea with the software implementation of the inverse mapping is just iterative applying forward rectification (Barrel model) until your algorithm converges to certain precision.<br/> [/quote]<br/> Well yeah, I was ...

Re: Exact Difference between different eVideoModes
Let me just add my experience to what Mike said: Precision Grayscale: : The cam seems to do a thresholding of the pic (i.e. the threshold property is used). The thresholded 1-bit picture is used as a mask over the cam's internal grayscale view, and you get the masked data to your PC. Basically the s...
