Simulink for PCV allows users to reconstruct a 3D view from multiple point cloud data generated from Simulink for NID. Simulink for PCV wraps OpenCV to enable to stitch over a million point cloud data such as 3D panorama view (and potentially SLAM view) with faster performance.
- OpenCV 2.3.1 for Windows 32bit/64bit (http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.3.1/OpenCV-2.3.1-win-superpack.exe/download)
- 32bit/64bit version of MATLAB R2011b or later
- Simulink for NID (http://www.mathworks.com/matlabcentral/fileexchange/32318-simulink-for-natural-interaction-device-nid)
- Computer Vision System Toolbox (highly recommended)

I setup successfully Simulink for PCV. But I can't use samples and don't see 'Point cloud viewer' in simulink.
Failed to find 'Template Matching' in library 'vipanalysis' referenced by 'nid_cvst_ocv_panorama360_qvga/vippanorama/Motion Estimation/Template Matching'
can you give me advice?
### Checking MATLAB version...
MATLAB version is OK with Simulink for PCV.
### Confirming Point Cloud Viewer installations with OpenCV...
### Setting MATLAB path to .\Lib and .\Lib\doc_en directory.
### Generating C:\Users\Win 8.1 VS8 X64\Downloads\slpcv\Lib\simulinkfornidopencvinfo.m
### Generating C MEX file for Point Cloud Viewer (OpenCV)...
Building with 'Microsoft Visual C++ 2010'.
MEX completed successfully.
### Successful completion of Point Cloud Viewer installations with OpenCV.
### Furthermore, manually, it needs to set Windows path to the folder which OpenCV dll stored.
### In case of 32bit version of MATLAB R2011b or later,
### set path to e.g. C:\opencv\build\x86\vc10\bin
### In case of 64bit version of MATLAB R2011b or later,
### set path to e.g. C:\opencv\build\x64\vc10\bin
It seems that you have not set Windows environment path to OpenCV installed directory, and then it causes the "...module could not be found" error.
Please check the step 4 in installation chapter of Simulink_for_PCV_En.pdf.
This is a superb material, is a step forward for the entire developers community. I appreciate a lot.
In my system:

How to solve the error (Invalid >MEX-file '...\Lib\sfun_pcv.mexw64': The >specified module could not be found)
It needs to set Windows path (not MATLAB path) to the folder which OpenCV dll stored.
- In case of 32bit version of MATLAB R2011b or later,
set path to e.g. C:\opencv\build\x86\vc10\bin
-In case of 64bit version of MATLAB R2011b or later,
set path to e.g. C:\opencv\build\x64\vc10\bin
I'm getting the same error (Invalid >MEX-file '...\Lib\sfun_pcv.mexw64': The >specified module could not be found). Have you had a chance to fix the error yet? If yes, looking forward to how I can fix it as well.
Also, if I wanted to add a 'Video to Workspace' block after the Pointcloud block, would it be possible? There isn't a output port. Is there a way to extract the XYZ data?
The latest 0.2.0 runs on 32bit and 64bit of MATLAB!, actually, 64bit seems to be faster than the other.
>but the model is not running (Invalid >MEX-file '...\Lib\sfun_pcv.mexw64': The >specified module could not be found.)
Yes, I have exact same error. It seems that .dll loading was failed. I need to do some investigation to fix the error.
Another good one Takashi!
I also tried to do the compilation with the 64-bit version of OpenCV. After some changes to the mex statement, the compilation finished successfully but the model is not running (Invalid MEX-file '...\Lib\sfun_pcv.mexw64': The specified module could not be found.)
Install 32bit version of MATLAB and OpenCV on 64-bit Windows.
I tried 64-bit version of OpenCV (e.g. 2.4.1), but some errors occurred during mex and simulation. Sorry for this restriction.
What should i do in order tom make it run on 64-bit windows?
