convert Flycapture2 Image to float*

Question

I am trying to save Flycapture2 image as a floating point EXR image. The pixel format that I get from the camera is YUV420 and I need to convert it to RGB in order to save it. What is the best way to do this? Precision is very important for this.

You can set your image format by using Flycapture SDK:

FlyCapture2::Format7ImageSettings fmt7ImageSettings;
FlyCapture2::Error error;

    fmt7ImageSettings.pixelFormat = FlyCapture2::PixelFormat::PIXEL_FORMAT_BGR;

    // Validate Format 7 settings  
    bool valid;
    error = cam.ValidateFormat7Settings(&fmt7ImageSettings, &valid, &fmt7PacketInfo);
    unsigned int num_bytes = fmt7PacketInfo.recommendedBytesPerPacket;


    // Set Format 7 (partial image mode) settings  
    error = cam.SetFormat7Configuration(&fmt7ImageSettings, num_bytes);
    if (error != FlyCapture2::ErrorType::PGRERROR_OK)
    {
        error.PrintErrorTrace();
    }
