New self-calibration method for rolling shutter cameras unveiled

Researchers have developed a novel self-calibration method for rolling shutter (RS) cameras, eliminating the need for calibration targets or specialized hardware. This new approach directly estimates camera intrinsics and readout time ratios from image sequences by employing a self-calibrating bundle adjustment technique. The method integrates two existing RS imaging models into a unified dual-projection model, enhancing geometric and temporal consistency for more accurate 3D vision applications. AI

IMPACT Enables more accurate 3D vision applications by simplifying camera calibration.
