In this post I am going to show you how to get started with the OpenCV CinderBlock. We are going to use the
TinderBox tool to create a skeleton Visual Studio 2019 project.
A CinderBlock is a prepackaged collection of code and libraries which implement a feature or exposes a library in Cinder. This includes bridges to libraries like OpenCV and FMOD, as well as standalone implementations of features like TUIO support. Cinder ships with several built-in CinderBlocks such as QuickTime and the LocationManager.
So let's dive in.
Get the sources
First we need the sources. We therefor need to clone cinder's master repository and also the OpenCV block.
git clone --recursive git://github.com/cinder/Cinder.git cinder_master git clone https://github.com/cinder/Cinder-OpenCV3.git
Prepare the CinderBlock
Next we need to manually make some edits to the block. Otherwise
TinderBox will throw an error at us that it cant find some libs when trying to create a new project.
Cinder-OpenCV3\cinderblock.xml and replace every occurence of
$(PlatformTarget) with either
x64. Then copy/move the whole folder
To be honest, I don't think that this is the intended way to use this block. Though it makes it work... if you know how this is ment to work, drop me an e-mail!
Create an empty project
Now we should be able to start
cinder_master/tools/TinderBox-Win. On the first dialoque choose the following values:
Template : OpenCV: Basic Project Name : CinderOpenCV Location : C:\Temp\CinderOpenCV Cinder Version: cinder_master Environment : VC 2015
Make sure that the platform matches you substituted bitness from the preparation step above.
On the dialogue page, where you can select the CinderBlocks to include, OpenCV3 should show up and the Install-dropdown should have the value
Adjust Project Properties
As a final step we need to modify the project so it uses the correct Plattform Toolset and Windows SDK version.
Right click on the project and under
Configuration Properties => General set the target platform toolset to
Visual Studio 2017 (v141) and windows SDK version to
You now should be able to compile and run the provided sample, that shows a blured image of an airplane.
One more thing. If you are looking for further cool
