Im searching for a function which geometrically transforms my thermal-camera-videostream onto an other videostream, but the cameras are (per hardware-size limitation) distanced from each other by about 10cm (thermal cam above the normal cam). I know the field ob views of both cameras. Does OpenCV have a function which solves said problem with the camera-distance? In the end i want both camera-streams to appear merged and correct overlaid in the object-height/width and position.

Thanks,

Steffen

Is there a function or workaround-method to horizontally concatenate 2 images together directly in CUDA? My program grabs 2 frames by highspeed-cameras, uploads them to CUDA, processes them and downloads them, then the images are concatenated by hconcat on the cpu (which i need to avoid as it drastically reduces my framerate) and displayed via OpenGL.

Surely its possible to stitch the images together via OpenGL, but i would rather like to do it via CUDA. I use OpenCV 3.0 and CUDA 6.5.

Just tested cv::cuda::demosaicing on my new nvidia-gpu, works like a charm :)

I recently tried to compile the "opengl.cpp"-sample with my MSVC11 2012 Express 32-Bit. Due to the MSVC saying GL/gl.h and glu.h producing over 100 failures (dont know why) i included freeglut and glew instead (thought it might work instead of just gl.h and glu.h). It compiles without failures and produces a grey window, but then crashes and says "namedwindow not compiled with enabled OpenGL" despite the fact that ive done this in cmake. The exact same opengl.exe-version produced by compiling of OpenCV.sln works just fine, but why?

Thanks,

I always thought my MSVC 2012 Express-Installation covers 64Bit-Code, but after your comments i learned that it only covers 32Bit. I once again built the DLLs and Libs with 32Bit and it all runs fine, thanks for your help! :) Will also try to include Win 7.1 SDK to get it working with 64Bit.

Ive downloaded OpenCV3.0 via Github and TortoiseGit from https://github.com/Itseez/opencv and build it via CMake without problems. Then I tried to compile it via MSVC11 2012 on my Win7 64bit-pc by opening OpenCV.sln and generating the Debug and Release-DLLs/Libs by pressing F7. opencv_cudev300d.dll/opencv_cudev300.dll and opencv_cudev300.lib/opencv_cudev300d.lib got built successfully, but after that i get mainly two errors: LNK1104: File "....\lib\Debug\opencv_core300d.lib" cannot be opened and MSB6006 cmd.exe gets executed with code 1

Anyone can help me out?

Thx for your answer, so i gotta use gpu::demosaicing via OpenCV 3.0 to do what i want. At the moment im using a AMD-GPU but for better performance i already thought about buying a faster Nvidia-GPU, although i wanted to support OpenCL instead of CUDA...

Hi, in OpenCV 2.4.9.0 ocl::cvtcolor Bayer->RGB is not supported. Will it be supported in OpenCV 3.0 and if: does it already work in 3.0-Alpha?

Thanks,
