we want to calibrate eight cameras we have mounted onto our vehicle. We followed the tutorial “static camera calibration” in the documentation. However, we have some issues.
According to the documentation, the images validation-<camera>.jpg generated after executing ./calibration-graph-cli --dir=<calib_data_path> should show a green overlay which indicate the quality of the calibration.
After executing ./calibration-graph-cli --dir=<calib_data_path>, in our case, the validation-<camera>.jpg images only show the blue dots on the targets and do not show the green overlay. The image below is an example of the output we obtain after executing the calibration:
We are using a Sony Alpha 6400 (ILCE-6400) with a sony 18-135mm objective (SEL 18135).
We used a fixed focal length of 18mm during the process.
It seems like we used auto focus during the capturing of the external camera images.
Can this be the reason for the failure of the calibration process (and the reason why the green validation rectangles are missing on the validation images)?
Why is an auto focus not allowed?
I did not mean the car cameras. My question was regarding the external camera you are using for the camera calibration. Can you please tell us the exact model and objective of the external camera you are using for the camera calibration process?
