Method of calibrating a computer-based vision system onboard a craft

This method of calibration comprising the reconstruction of a 3D mapping of 3D landmarks of an environment on the basis of digital images of the environment captured by the computer-based vision system (10) during the movement of the craft (2) along a trajectory.

More Information
Summary:This method of calibration comprising the reconstruction of a 3D mapping of 3D landmarks of an environment on the basis of digital images of the environment captured by the computer-based vision system (10) during the movement of the craft (2) along a trajectory. It comprises the optimization of at least one 3D mapping corresponding to a first sequence of images by considering at least one extrinsic parameter and/or at least one intrinsic parameter and/or at least one parameter of poses and/or one parameter of 3D landmarks as constant and the optimization of at least one 3D mapping corresponding to a second sequence of images, longer than the first image sequence and including the first image sequence, by considering said at least one extrinsic parameter and/or said at least one intrinsic parameter and/or said at least one parameter of poses and/or said at least one parameter of 3D landmarks as variable so as to estimate it.
