Abstract: Estimating the principal point for vehicle-mounted fisheye cameras is essential for accurate vision tasks. However, traditional calibration methods require human intervention and specific patterns, lacking flexibility and adaptability to different camera models during camera change.… read more here.

DOI: 10.1109/lgrs.2022.3179645
Abstract: We consider the problem of structure-from-motion (SfM) for images with varying principal point (PP) but otherwise fixed calibration. This scenario occurs for archival imagery taken using historic glass plate and film cameras without fiducial markers,… read more here.

Abstract: Abstract. We present an improved calibration method to optimize and simplify the current principal point estimation model and the zoom lens calibration process. A Euclidean distance weighting model (EDWM) for the principal point is constructed,… read more here.
