Basic usage of Intel RealSense cameras with CVB

Hi @c.hartmann

Thanks for your response! I’m a colleague of @KKulikovskis and maybe I can provide some more details.

We have not installed any TL specifically, just CVB from the installer.

Although I noticed that the cameras show up in CVB GeniCam Browser
browser

This is the small example code where the problem presents itself:

#include <librealsense2/rs.hpp>
#include <iostream>
#include <cvb/device_factory.hpp>

int main(int argc, char *argv[]) {
    rs2::context ctx;
    auto list = ctx.query_devices(); // Get a snapshot of currently connected devices
    if (list.size() == 0)
        throw std::runtime_error("No device detected. Is it plugged in?");
    rs2::device dev = list.front();

    rs2::pipeline pipe;
    pipe.start();

    std::cout << "started" << std::endl;
    return 0;
}

The application crashes at pipe.start() with free(): invalid pointer.

But if the CVB include #include <cvb/device_factory.hpp> is removed then everything is ok.

Just a little extra information: If you have the GEV Variant (i.e. not USB of Realsense) then my Transportlayer won’t help you and you don’t need it.

But i got good news for you, if you do the acquisition via librealsense, then you don’t need device_factory.hpp. (I was not aware that librealsense handles GEV devices).

As for the error itself, no idea, i can be a dependency (like libjpeg as an example, which librealsense needs in a different version). But more like is, that there is a define overridden. Check the compiler warnings. BUT this is just a silly coincidence then.

To clrafiy - we are not using cvb/device_factory.hpp with regards to our Realsense cameras in any way.

We have a teledyne camera that we use in the same application, that is used through CVB. @OskarsO Example was to illustrate that we have pinned down the problem to these 2 includes conflicting in some way.

CVB is being used exclusively with Teledyne camera in our application, but this error still happens.

And All of our cameras (Realsense and Teledyne) use LAN connection - there are no USB devices.

I would check with Realsense logging, where the error is. Otherwise this is a bit out of our control.

Hello,

I seem to be unable to install the driver for the realsense camera.
Whenever I try to install them i am prompted with an error message that basically states I do not have an up-to-date version of Common Vision Blox.

The error message says “Der Common Vision Blox SI UVC RS TL (x64) setzt voraus, das Common Vision Blox (x64) 13.01.000 oder neuer auf ihrem System installiert ist”. (In engl.: "The Common Vision Blox SI UVC RS TL (x64) requires Common Vision Blox (x64) 13.01.000 or higher being installed on your system).

I tried to install both the 64-bit and 32 bit version of both Common Vision Blox and the RealSense driver.
I verified the version of Common Vision Blox via the GenICam Browser to be 14.01.005 (64 bit).
I am running the OS Windows 11.

It is not obvious to me what I did wrong, maybe the mechanism for detecting Common Vision Blox is erroneous within the Realsense driver.
Or maybe there was an API breaking change between major version 13 and 14 and maybe I would need to install a version 13.00 < x < 14.00.

If anyone has encountered this issue before and found a workaround please let me know.

Greetings

Hi @Mojaeng ,
You did nothing wrong. The setup is not compatible with CVB 14. And does not make the check right.
I am sorry for that.

The RealSense TL works with CVB 14. To get it without the setup please contact de.support@stemmer-imaging.com
And link this post to it. Then we can send you the needed file.
