Trying to configure OpenCV 3.1 Viz Module with Visual Studio 2015

Hello all,

I am currently trying to configure my Visual Studio to work with the Viz module for OpenCV for a 3D scanning project I have been working on. My build of OpenCV only had a build and sources folder. I added the viz.hpp and corresponding headers to the opencv2 directories within the include folder and it shows no errors. I am getting an error when trying to build my project saying that there are some unresolved external symbols, which make sense as there isn't a definition for some of these declared methods, which point to the needed module folder viz. In the viz folder, it contains all the C++ files for the needed headers, I am just struggling to make them visible to the project. Adding them to the included source directories of my properties file seemed to not change the error.

Tl;dr version: I need to configure Visual Studio to recognize and source the Viz module properly.

Any help would be greatly appreciated!

I'm not sure if it worked, I was able to compile both of them and in the resulting opencv folder there is no build or source folder present and there's a bunch of install VC++ files in every directory along with cmake directories. I am using Visual Studio to compile the code.

"I was able to compile " have you build opencv with samples? have you got dll in bin/debug or bin/release

I am not seeing a build folder with samples. I am getting the debug and release folders https://gyazo.com/ea61d8398bbe74d1186d89159a5d01ed (https://gyazo.com/ea61d8398bbe74d1186...) https://gyazo.com/8c720a6b12022cf847b7d4ea5c26d898 (https://gyazo.com/8c720a6b12022cf847b...) but I am not seeing the build or source folder like in the common .exe installer for windows that I would expect for including in Visual Studio https://gyazo.com/c728a1943a39cc8a7adacf8bbe0a95c5 (https://gyazo.com/c728a1943a39cc8a7ad...) . Thank you for your help LBerger with this, I've been really struggling

I made some video. I supposed that you have already build Vtk in g:/lib/vtk/build using cmake

1 Clone opencv

2 Clone opencv_contrib

3 Use Cmake first part and second part

4 build opencv using VS 2015 without CUDA and withvtk

If there is no sensitive information, you could consider hosting your videos as tutorial videos on a more generic platform like YouTube.

You're tutorial worked well! I didn't use the opencv_contrib when building my solution the first time. Thanks!
