The Agisoft Lens User Manual provides information and guidance on the use of Agisoft Lens. Agisoft Lens is an automatic lens calibration software, which uses an LCD screen as a calibration target. It supports estimation of the full camera calibration matrix, including non-linear distortion coefficients. Estimated calibration parameters can be saved in human readable file format for subsequent use in the software, where precise camera calibration data is required.
Agisoft Lens estimates the following camera calibration parameters:
• fx, fy – focal length
• cx, cy – principal point coordinates
• K1, K2, K3, P1, P2 – radial distortion coefficients, using Brown’s distortion mode
