Abstract: Methods of generating a camera model are provided. A robotic assembly is used to move a calibration assembly relative to a camera assembly through a series of poses. The calibration assembly comprises a calibration target and markers. The camera assembly comprises a mount, a camera having a field of view, and markers. The predetermined series of poses, together, cause the calibration target to pass through the field of view of the camera. The camera is used to generate a respective image of the calibration target. A tracker is used, to determine respective locations in space of the markers. A transformation function is generated that maps onto a three-dimensional space the stored coordinates and determined locations in space of the markers and features of the calibration target. The transformation functions are used to generate a model of parameters of the camera. Systems are also provided.
