Re: Camera images to OpenCV

<r>[quote=davidtheory]Hi guys, thanks for the help.<br/> <br/> My settings for one cam are:<br/> <br/> mycam->SetVideoType(CameraLibrary::MJPEGMode); <br/> mycam->SetAEC(true); <br/> mycam->SetAGC(true); <br/> <br/> is this the best configuration for speed increasing in openCV? for real time?<br/> [...

Re: Camera SDK + Qt linking problem

<r>[quote=NaturalPoint - Doug]I'm hoping to add a QT sample app to the Camera SDK to help minimize the pain of this. [/quote]<br/> Just a quick note: If you compile OpenCV with the option WITH_QT (and optionally WITH_QT_OPENGL) and use the commands cv::namedWindow() and/or cv::imshow(), then you hav...

Re: Camera SDK + Qt linking problem

<r>I'm using the Camera SDK beta 1.0.1 (which is the same as final 1.0.1), Qt 4.7.1, Windows 7 32bit, and Visual Studio 2008. It all works like a charm. I'm not too familiar with g++ unfortunately.<br/> <br/> I'd advise you to do the usual step-by-step debugging: Remove/comment all references to Cam...

Re: which cameras for active IR tracking

<t>[quote=zsero]<br/> - Do different NaturalPoint cameras process IR blobs inside the camera and if yes, how many IR markers do they support? In cameralibraryglobals.h I've seen max objects 500, but it seems a bit too much. Tracking 500 IR blobs in real time would take a huge amount of processing, n...

Re: Camera images to OpenCV

Hi David, as Birch suggested, I did look at the examples from the SDK. I also browsed the header files of the camera SDK. It happens that I also use 6 cameras. It all works flawlessly. I stripped everything down to the bare minimum for my needs, that means, I initialize the camera manager: CameraLib...

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

Thanks, the frameID is a good tip :-).

So if I get those overflows, I could use GetLatestFrame() in this one case to flush the frame queue, and keep on using GetFrame() again as long as I can keep up?

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

Hi, I'm using Camera SDK 1.0.1 beta 1 and V100R2 cameras. I noticed there are 2 similar functions: Frame * GetFrame(); //== Fetch next available frame =======---- Frame * GetLatestFrame(); //== Fetch latest frame (empties queue) --- What is the exact difference between them? Is there a way to see ho...

Camera images to OpenCV

Hi, for all of you who'd like to get the bitmap of a camera frame into an OpenCV matrix, have a look at the code sample below. This post applies to OpenCV 2.2 and CameraSDK 1.0, but should be adaptable to other versions easily. // pMyCam is of type CameraLibrary::Camera * int camWidth = pMyCam->Widt...
