Hi,

I get this error when I run sudo ./calibration-graph-cli --dir=/usr/local/driveworks/tools/calibration/calibration_data

Terminating app due to unexpected exception:
Could not make progress initializing the world positions. This probably indicates a disconnected graph. Check that all targets are detected in the images and that there are enough targets and images to link all cameras. Nodes with missing poses: external,

I have added 52 images from the external camera. I am using targets 90-97. I have attached my terminal output below.

Hi @mamoona.b.shami
We will check internally and get back to you. Thanks.

Looks like you don’t have a complete graph. Image should be connected to all other images by observing the same targets, maybe they have some isolated observation.

This can also happen if some targets don’t get detected if they are too far away or too blurry or something.
