Geometric Wide-Angle Camera Calibration: A Review and Comparative Study

Understand

Wide-angle cameras are widely used in photogrammetry and autonomous systems which rely on the accurate metric measurements derived from images.

• To find the geometric relationship between incoming rays and image pixels, geometric camera calibration (GCC) has been actively developed.
• Aiming to provide practical calibration guidelines, this work surveys the existing GCC tools and evaluates the representative ones for wide-angle cameras.
• The survey covers camera models, calibration targets, and algorithms used in these tools, highlighting their properties and the trends in GCC development.
