Where should I include ueye libraries?

Hi guys,

I am going to use ueye camera for image processing and am totally new in this field. I have already installed Visual community and opencv following this tutorial: https://www.youtube.com/watch?v=7SM5O... I have runned one sample program included also in this tutorial and included the opencv folders in the project settings.

However, I don't understand yet, where should I include the ueye libraries (including e.g. ueye.h and uEye_api.lib etc.) and why do we use openCV? I just have been told that we should use opencv with visual studio for image processing!

Thanks you!

opencv is a computer-vision and machine-learning library.

if all you want is image processing, you don't need it.

(also, we can't really help with any ueye problems (off-topic))

thanks for your response. But could you please explain what do you mean exactly by if all I want is image processing? What else could be needed? I'm asking because I am new and the whole thing I am going to do is not yet clear. I might need something else in the future.

what do you want to do ?

With help of one ueye camera I want to take pictures of some patterns and then measure some distances (e.g. between two points or measuring the middle point between two lines).

yes, sure. i probably just misread you above, ignore.

So I should use only openCV and no need to include ueye libraries. Am I right? I didn't get the answer "yes" exactly :)

I used uEye cameras just a bit a long time ago; so I don't really remember the API. Anyway, you add #include <ueye.h> at the beginning of your cpp file that does the capturing (main.cpp), and the lib file in the project properties->linker->additional dependencies.

Then, use the uEye SDK documentation to implement your capturing code. At one point you should have something like : uchar *data; ... camera_capture(data);. There, you can create an OpenCV image object: Mat img(height,width,data,CV_8UC3);

Anyway, you can use OpenCV for the tasks you need, however you'll need some good C++ programming skills and understand the bases of image processing and OpenCV. I recommend to take some photos and work with them, and add the live processing part later.

Thank you. It is really helpful.
