I would like to get this demo running in my QTcreator. I' running this on osx 10.7 and i have the latest opencv installed. I can run this demo outside the qt creator but that's all. I was wondering how to make this work as a QTcreator project.
This can be solved by opening the cmake file in qtcreator it will then load all the files an can be compiled .

Basically I am developing a project using OpenVino and OpenCV,to do so I cannot use the normal and easy way of using pip to install opencv library but instead Intel provided their own optimized version OpenCV.
I cannot find a place to add the path for the custom OpenCV in pycharm.
If anybody can enlighten me,please do so.
Thank you in advance.
please try the below steps.
Install Python 2.7.10
Install Pycharm(If not installed previously)
Download the OpenCV executable.
Install OpenCV
Add OpenCV in the system path(%OPENCV_DIR% = /path/of/opencv/directory)
Goto C:\opencv\build\python\2.7\x86 folder and copy cv2.pyd file.
Goto C:\Python27\DLLs directory and paste the cv2.pyd file.
Goto C:\Python27\Lib\site-packages directory and paste the cv2.pyd file.
Goto PyCharm IDE and goto DefaultSettings>PythonInterpreter.
Select the Python which you have installed on Step1.
Install the packages numpy,matplotlib and pip in pycharm.
Restart your PyCharm.
PyCharm now has OpenCV library installed and working.
Hope this will solve your issue
We recently decided to use Android Studio's CMake support as a part of our development, and as far as compiling and building is concerned everything works fine for the development team.
As a part of our validation efforts we are also running Jenkins for continuous testing, and that's where the problems are starting. The machine running Jenkins does not have Android Studio installed, nor it has an UI. As such it only possesses the android NDK and SDK. However, when running tests, the following error occurs :
Failed to find CMake.
Install from Android Studio under File/Settings/Appearance & Behavior/System Settings/Android SDK/SDK Tools/CMake.
Expected CMake executable at /home/vagrant/android-sdk-linux/cmake/bin/cmake.
The problem now is that there is no way to install CMake like suggested ! The machine does not have any UI to run Android Studio, and the command line tools feature no option to install CMake. And creating sym-links isn't the solution either, as CMake isn't the only thing it's looking for.
How am I supposed to make my project work on the machine ? CMake is running perfectly (as it was already used as part of the tests) so the problem is only coming from Gradle looking only in the SDK directory for it...
The problem now is that there is no way to install CMake like suggested
Actually it is not! Instead of using android list sdk command for installing sdk packages you should use new command line tool: sdk-manager.
Ndk, cmake are available for installing through this new android sdk tool.
you need to install manually cmake on your system unix:
go to your android sdk directory ${ANDROID_HOME} and create new cmake folder with:
wget "https://dl.google.com/android/repository/cmake-3.6.3155560-linux-x86_64.zip"
unzip -q cmake-3.6.3155560-linux-x86_64.zip -d ${ANDROID_HOME}/cmake
add to PATH ENV ${PATH}:${ANDROID_HOME}/cmake/bin
I was trying to install lejos on my laptop which has windows 8.1.
I downloaded eclipse 32bit.
I installed lejos plug in in eclipse.
I installed leJOS_EV3_0.9.0-beta_win32_setup.
Now i went to eclipse and created lejos nxt project. The problem that the project has red (!) and when i create a class it has error:
Description Resource Path Location Type
Unbound classpath container: 'org.lejos.nxt.ldt.LEJOS_LIBRARY_CONTAINER/nxt' in project 'test' test Build path Build Path Problem
What did i do wrong?
Ok after some more research I found a good video which explain how to install lejos on pc correct way. So after combining this video and eclipse install tutorial i was able to create class and run my first program.

I have started to work on Rpi. I have worked on opencv on windows and ubuntu. Now I want to do Image porcessing on Rpi. I have installed latest version 2.4.8 on my Rpi. And I am able to open and display an image. However when I am trying to open webcam and display, it gives me error: HIGHGUI ERROR: v4l/v4l2: VIDIOC_CROPCAP.
Can anyone tell whats the problem ?
I haved the some error when trying to execute a code that does facedetection , i solved it by adding the files needed in my working folder (source folder).
you can show us the code to find out what exactly you need
If you are using prebuilt binaries, they may be built without v4l support. Try to build your own OpenCV with v4l checked. And of course before that install v4l with development files. You can follow this tutorial with how to install required dependicies explanied.
I was installing QT5 and OpenCV 2.4.4 with CMAKE 2.8.10.2..
I was following the instruction from here and here .
The problem is, when I want to compile the OpenCV library with cmd, 'mingw32-make' is not recognized as internal or external command, operable program or batch file.
I don't know how to react, I've follow the instruction step by step..
Thanks for your answers :)
===============================
This question has been answered :)
the answer is I didn't put the path contains mingw32-make.exe (Qt5.0.2\Tools\MinGW\bin) to system variable. different version different path, made me confuse.
So, if you want to integrate Qt 5.0.2 and OpenCV 2.4.4 with CMAKE 2.8.10.2 in Windows 7, use instructions from two links that I mention it above, it works! Thanks:)
In start menu you can find pre-configured environment variable command prompt link for Qt MinGW. If you are using Qt 5.0.2 for Windows 32-bit (MinGW 4.7, 650 MB) you may find something like Qt 5.0.2 for Desktop (MinGW 4.7). Use it for your command. Please make sure you are using mingw32 version of Qt otherwise the command you are looking for is nmake.
