2017-05-10 16:31:21 -0500 asked a question Installation of OpenCV with Libraries from the Source Files

I have already read the tutorial on the opencv webpage and it is just way too old and almost useless.

I want to build OpenCV with QT support using Visual Studio 2017.

(Why VS2017 you might ask, Microsoft is pushing out VS2017 now. The support for 2015 is limited and it does not ship with c++ compilers anymore and it is hard to set it up and working, and almost impossible to have it functional alongside VS2017)

So far I have tried:

  • OpenCV 3.2.0, QT 5.8 and VS 2017. QT5.8 can not be compiled, this is already reported to QT issue tracker
  • OpenCV 3.2.0, QT5.7.1 and VS 2017. QT compiles with some issues, cmake generates but the generated lib still generate errors in VS 2017

Does anyone know a solid combination of this three software that works together, basically VS2017, any version of OpenCV and QT?

@gregoireg could you share your final code/result?

@RonM, did you ever try the solution suggested above?

@Tetragramm, Thanks for the reply, some question though, I mentioned which camera I plan to use, is that not enough information? Also using a capture card, couldn't I do

cap = cv2.VideoCapture(0)
cap = cv2.VideoCapture(1)
cap = cv2.VideoCapture(2)

To read from all the cameras? (please also see updated question with more info)

Hi, I have just started to use openCV and I am very new to image/video processing and stitching so please bear with me while I explain what I am trying to accomplish.

  1. I plan to purchase 3 HERO5 Black and connect them to a PC via HDMI
  2. For this I plan to use the following Capture Card,
  3. I plan to buy the following NVIDIA Graphic Card Nvidia Titan X, for processing the images
  4. The cameras position/angle between each other will be fixed.The cameras will be moving with respect to the world, so the scene will be changing.

I would like to use openCV and preferably python to stitch real-time videos from these cameras into one video.

So first of all, I must start by asking

  • Is the hardware I plan to purchase sufficient to solve the task? (is GoPro a good choice to do live video editing?)
  • Does OpenCV support reading video feed from this capture card/HDMI input?
  • Should I focus on using Linux or Windows, what platform is better supported by OpenCV? (hopefully not MAC)
  • Where/How should I start with the programming? Are there simple OpenCV examples for reading HDMI feed and stitching out there as I believe someone else has already tried to solve this problem? I found the following link, but the project is too complicated for me to start with directly, (this seems to difficult to start with)

Any help is appreciated.
