Inside that directory, make a new file called “CMakeLists.txt”. To test your OpenCV, make a new directory named “Video_Capture” anywhere inside your disk. We tell CMake to build in Release mode fully optimized, no debugging capabilities): cmake -D CMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local. First, make a new directory called “Release” inside the “opencv” directory and open it: cd OpenCV & mkdir Release & cd Release Once the cloning has finished, we must build OpenCV through CMake. Open up your working directory and use the following commands inside that directory to clone the OpenCV repository via git: git clone
Opencv cmake linux install#
To install these dependencies, type in the following: sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev In addition to the required dependencies, OpenCV also has a list of optional dependencies it uses. Sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev In order to save time, type in the following commands in a terminal to install the necessary prerequisites: sudo apt-get update
OpenCV requires a host of various dependencies to function properly. In the following blog post, we will go through the steps necessary to compile OpenCV 3.0 from source on Ubuntu 14.04 and capture a video through your computer’s own webcam. Unlike PCL, however, OpenCV is a 2D imaging library, making OpenCV just as useful to have for machine vision. OpenCV is an open-source library that supports real-time computer vision.
