Published in 2025 at "IEEE Transactions on Instrumentation and Measurement"

DOI: 10.1109/tim.2025.3638923

Abstract: In industrial microvision systems, challenges like mounting parallelism, mechanical vibration, and thermal drift often cause frequent and nonuniform defocus, which degrades traditional corner detection and complicates camera calibration. While phase-based techniques are robust to defocus,… read more here.
