I'm trying to get a videostream from gigE Baumer txg12 camera, to use it in my openCV app. But I don't know how to achieve it.
Does anybody have experience with using Baumer SDK with openCV?
How can I get my video-stream?

So I was using OpenCV to capture from my webcam, although I have hit a problem. Seems OpenCV has no way of detecting if the camera has been disconnected. So I was wondering if anyone knows any other webcam APIs for c++ that could be used as an alternative, or if anyone knows how to detect disconnected/reconnected webcams using OpenCV I could even continue using that.
I found retrieve function in OpenCV for web camera.
https://github.com/BelBES/HandDetector/blob/master/main.cpp
cv::VideoCapture cap(CV_CAP_OPENNI);
cap.retrieve(mat, CV_16UC1);
Can I retrieve it the same way in iOS?
I tried like following, but it shows just black.
mat.convertTo(depthMap, CV_8UC1, 1.0/255);
Any idea?
Or, How can I convert this main.cpp for iOS?
In iOS framework opencv2.framework, there is a type CvCapture, which is the cv::VideoCapture in C++:
Try it.
I am a beginner to ubuntu. I am trying to drive a external camera on ubuntu 15.04. I want to know how to combine opencv library with camera driver. So I can capture video use sentences like
VideoCapture cap;
cap.open(0);//0,1,2...
Does anyone have some idea? Looking forward to your reply!
It depends on the camera you use, some cameras you need do nothing, and some cameras give API,you can use the API to get the video then use opencv to do something.
I would like to know how OpenCV does to find devices that it can read from?
Can OpenCV only read from usb devices?
I have a video acquisition card (BlackMagic Intensity) and I until now used the blackMagic's SDK to retrieve the stream coming from the input port on the card, and converted it to a cv::Mat that I then use in my code.
But can't I not develop some kind of C++ plugin for OpenCV so that I can use VideoCapture to access my blackMagic stream? wouldn't it be a cleaner way of doing this?
Hope you can help
I am using OpenCV 2.4 with C++ for image processing and video streaming . I would like to know how we can use fire-wire camera like pixilink to capture frames? I tried the VideoCapture class but it seems to work with only usb cameras unlike firewire one. If some one has done same thing with firewire camera then kindly give some guidance how to do that?
You can capture images using firewire SDK or you can also libdc1394 API. I found libdc1394 to more reliable and easy to use and there are couple of examples available to get start.
