Installing Open. CV 2. Ubuntu 1. 2. 0. 4 LTS Sebastian Montabone. EDIT I published a new guide using Ubuntu 1. LTS and Open. CV 2. The latest Long Term Support version of Ubuntu1. LTS is out and a new version of Open. CV was released as well. This means that now is a great opportunity to update my Open. CV installation guide to the latest versions, Ubuntu 1. LTS and Open. CV 2. We are going to setup Open. CV to use the new Qt highgui interface, which is much better than the simple highgui interface. Also, we will install Open. CV with support for Open. GL, as well as reading and writing videos, access to a webcam, Python, C and C interfaces, and Intel Threading Building Blocks TBB. OK, so the first step is to make sure that everything in the system is updated and upgraded. Now, you need to install many dependencies, such as support for reading and writing image files, drawing on the screen, some needed tools, etc This step is very easy, you only need to write the following command in the Terminal. Time to get the Open. CV 2. 4. 1 source code. Open. CV 2. 4. 1. Open. CV 2. 4. 1. Open. CV 2. 4. 1. Now we have to generate the Makefile by using cmake. In here we can define which parts of Open. CV we want to compile. Since we want to use Python, TBB, Open. GL, Qt, work with videos, etc, here is where we need to set that. Just execute the following line at the terminal to create the appropriate Makefile. Note that there are two dots at the end of the line, it is an argument for the cmake program and it means the parent directory because we are inside the build directory, and we want to refer to the Open. CV directory, which is its parent. D WITHTBBON D BUILDNEWPYTHONSUPPORTON D WITHV4. LON D INSTALLCEXAMPLESON D INSTALLPYTHONEXAMPLESON D BUILDEXAMPLESON D WITHQTON D WITHOPENGLON. Check that the above command produces no error and that in particular it reports FFMPEG as YES. If this is not the case you will not be able to read or write videos. Also, check that Python, TBB, Open. GL, V4. L, Open. GL and Qt are detected. If anything is wrong, go back, correct the errors by maybe installing extra packages and then run cmake again. You should see something similar to this Now, you are ready to compile and install Open. CV 2. 4. 1. sudo make install. Now you have to configure Open. CV. First, open the opencv. Add the following line at the end of the fileit may be an empty file, that is ok and then save it. Run the following code to configure the library. Now you have to open another file. Add these two lines at the end of the file and save it. PKGCONFIGPATHPKGCONFIGPATH usrlocallibpkgconfig. PKGCONFIGPATH. Finally, close the console and open a new one, restart the computer or logout and then login again. Open. CV will not work correctly until you do this. Now you have Open. CV 2. 4. 1 installed in your computer with Python, TBB, Open. GL, video, and Qt support. Check out the cool Qt interface which provides image viewing capabilities with zoom, as well as the ability to save the current image with just one click. If you zoom in enough, you can see the RGB or intensity values for each pixel. Now lets build some samples included in Open. CV. cd Open. CV 2. Now we are ready to run the examples. Open.
