Your question is Stereo Camera Extrinsics From Async Images. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You have two cameras that output asynchronous images with partially overlapping fields of view. How can you estimate the extrinsic transform between the cameras?
Explain how you would handle timestamp offset, camera intrinsics, feature correspondence, robust geometric estimation, and validation. Discuss both an offline calibration workflow and how you would detect calibration degradation during operation.
