Getting info of camera devices.

Kira

Hello all,
I tried to get the name of camera devices in Qt referring the sample camera example.
Their i can see the names of camera with their names in readable form but when i
use the same code in my program i get a long value with the names how can i separate the info to get the short names.
Sample code:

std::cout<<"Entering camera function \n";
    QList<QCameraInfo> cameras = QCameraInfo::availableCameras();
    foreach (const QCameraInfo &cameraInfo, cameras)
       // QVariant::fromValue(cameraInfo.deviceName());
        qDebug()<< "device:"<< QVariant::fromValue(cameraInfo.deviceName());
    std::cout<<"Exiting camera function \n";

Output:
device: QVariant(QString, "@device:pnp:\\?\usb#vid_04f2&pid_b5a7&mi_00#6&fea6f4d&0&0000#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global")
device: QVariant(QString, "@device:sw:{860BB310-5D01-11D0-BD3B-00A0C911CE86}\Basler GenICam Source")
device: QVariant(QString, "@device:sw:{860BB310-5D01-11D0-BD3B-00A0C911CE86}\Basler GenICam Source 2")
device: QVariant(QString, "@device:sw:{860BB310-5D01-11D0-BD3B-00A0C911CE86}\Basler GenICam Source 3")
device: QVariant(QString, "@device:sw:{860BB310-5D01-11D0-BD3B-00A0C911CE86}\Basler GenICam Source 4")

Also, i have only 2 cameras connected. But in the output i can see multiple cameras.

Hi,

That because your camera is seen through different interfaces. The GenICam standard does offer different ways to access your camera which might not correspond to the number of device.

@SGaist : Thanks.
Is there any way to get the names of camera like:
webcam
Basler GenICam Source
Basler GenICam Source1
From the list given above.

@Kira You can extract the name from the strings

Kira

Sure thanks.

pylon Basler camera

Have you tried using the pylon camera suite free software?

i need to support this camera

You may want to tell what make/model your camera is.
In addition, what connection type is (USB, IP, etc.)
The above mentioned framework provides some tools (viewer, configurator) that may also help you.

@Pablo-J-Rogina I used that software, actually i want to use Basler integrated in qt but first I need to get a list of Basler connected to the system, select one of them then get the frame from Basler then give that frame to OpenCV for process

Hi,

Then you need to use the SDK provided with pylon. There's everything there to enumerate the cameras connected to your system as well as grab images from them.
