Universal Geometric Camera Calibration With Statistical Model Selection, Chistopher Paul Broaddus
Universal Geometric Camera Calibration With Statistical Model Selection, Chistopher Paul Broaddus
Masters Theses
We propose a new universal camera calibration approach that uses statistical information criteria for automatic camera model selection. It requires the camera to observe a planar pattern from different positions, and then closed-form estimates for the intrinsic and extrinsic parameters are computed followed by nonlinear optimization. In lieu of modeling radial distortion, the lens projection of the camera is modeled, and in addition we include decentering distortion. This approach is particularly advantageous for wide angle (fisheye) camera calibration because it often reduces the complexity of the model compared to modeling radial distortion. We then apply statistical information criteria to automatically …
