Recfusion SDK Multi sensor calibration

I recently bought recfusion sdk and finding out how to use it.
I am using two intel realsense D455.
For the given sample code, I run those one by one and stuck in MultiSensorCalibration.
it seems to stop when it goes through “calib.calibrate()”. (Check with QMessageBox::information():wink:

I don’t know what is causing the problem…

It may seem little bit elementary but yet I am not an expert in programming.

Perhaps the marker is not visible (well enough) in the two images you pass into the calibration. You could save the images in the GUI application and if it works there and you feed the same images into the calibration in your code, it should then also work.
