We started experimentations considering new camera models more accurately adapted to the real optical systems of a fetoscope. We defined different image formation models to evaluate (thick lens model, GRIN Lens, …). We currently try to establish mathematical properties which will allow us to estimate fluid-immersed calibration parameters based on a dry calibration.
We prepared a calibration dataset based on the pinhole camera model (2D mosaicking RSG meeting).
