Normally you won't get errors while compiling, so you don't need to debug. If you need to customize OpenCV, then you have to recompile it.

Hi, Thanks but I found a way to get Kinect.

My problem is: - with this line: CvCapture capture cvCreateCameraCapture( 0 ) I can only capture my webcam (integrated to my laptop) stream. I found a function with openCv, using a checkerboard. Using the Python library (with pip install.) will get you a precompiled library too. Hello everyone, I need the intrinsic parameters of the Kinect camera for my work. This is valid for OpenCV library, no matter if you built it yourself or downloaded it. Just make sure that the include folders and the library ( opencv_worldXXX.lib) are added to your Visual Studio project, and the OpenCV DLL file ( opencv_worldXXX.dll) is accessible by the executable. Unfortunately I agree that external libraries in Visual Studio and compiling big projects is a real PITA.Дownloading the OpenCV library for windows from the site will give you a library that's ready to be employed. The compilation is handled by the Visual Studio compiler called cl. video codecs) and the available hardware in your machine (e.g.

#Opencv cmake install#

sudo apt install libavcodec-dev libavformat-dev. Video/Audio Libs - FFMPEG, GSTREAMER, x264 and so on. sudo apt install libjpeg-dev libpng-dev libtiff-dev. Generic tools: sudo apt install build-essential cmake pkg-config unzip yasm git checkinstall.

It generates the project files ( SLN for Visual Studio or Makefile for make/gcc) according to your needs (you can select the modules you need), the installed libraries (e.g. How to install OpenCV 4.5.2 with CUDA 11.2 and CUDNN 8.2 in Ubuntu 20.04. I want to be able to debug the errors from the compiling phase and for that I need to know why the special treatment for the c++ library compared to the python one? Why do I need to compile opencv and why does it need to be done with cmake? Does pip install opencv-contrib-python also compile opencv behind the scene? Is that systematic for all libraries? I followed this tutorial but it teaches how to install opencv per project, so is that it? Does compiling allow you to add opencv globally?Д¬Make is not for compiling OpenCV, it's just a configuration utility. Python opencv is just a bunch of shell commands away, but the c++ library is a nightmare especially that it involves working with visual studio which, on its own, is pain to get to work properly.

To build this using CMake, we create a file named CMakeLists.

At first, I just wanted to follow the instructions to install opencv on windows and move on since I thought the task itself is pretty straightforward, but then I got hit with some serious looking error messages when I tried to 'compile' c++ opencv (step 6.1 in this tutorial). If you have been working with OpenCV for some time, you should have noticed that in most. I just got an internship and I was tasked to generate dll files from c++ class and function definitions that call to the opencv library.
