Paper Abstract

According to camera calibration requirements of close-range photogrammetry system, novel camera calibration method based on dynamic three-dimensional (3-D) optical plate is proposed. The dynamic 3-D optical plate is realized by translational moving a 2-D optical mask plate with elaborately designed targets alone a granite linear guiding rail. 2-D direct linear transformation for camera external parameter decomposition is studied, and mathematical model for camera internal parameter calibration is built based on bundle adjustment. The feasibility of dynamic 3-D optical plate and camera calibration method are experimentally demonstrated.
