Abstract: Apparatuses, systems, and methods dynamically model intrinsic parameters of a camera. Methods include: collecting, using a camera having a focus motor, calibration data at a series of discrete focus motor positions; generating, from the calibration data, a set of constant point intrinsic parameters; determining, from the set of constant point intrinsic parameters, a subset of intrinsic parameters to model dynamically; performing, for each intrinsic parameter of the subset of intrinsic parameters, a fit of the point intrinsic parameter values against focus motor positions; generating a model of the intrinsic parameters for the camera based, at least in part, on the fit of the point intrinsic parameter values against the focus motor positions; and determining a position of a fiducial marker within a field of view of the camera based, at least in part, on the model of the intrinsic parameters for the camera.

Abstract: Apparatuses and methods determine the three-dimensional position and orientation of a fiducial marker and tracking the three-dimensional position and orientation across different fields-of-view. Methods include: capturing an image of a first space in which the fiducial marker is disposed with a first sensor having a first field-of-view; determining the three-dimensional location and orientation of the fiducial marker within the first space based on the image of the first space in which the fiducial marker is disposed; capturing an image of a second space in which the fiducial marker is disposed with a second sensor having a second field-of-view; calculating pan and tilt information for the second sensor to move the second field-of-view of the second sensor to acquire an image of the fiducial marker; and determining the three-dimensional location and orientation of the fiducial marker within the second space based on the image of the second space.

Abstract: An aircraft component failure prediction apparatus including a database and an aircraft maintenance controller coupled to the database. The controller classifies operational data, in a first classification, as corresponding with at least one maintenance message to form at least one classified multidimensional operation data matrix including classified data. The controller classifies the classified data of the at least one classified multidimensional data matrix, in a second classification, to predict an occurrence of a future maintenance message for the aircraft component. The controller preprocesses the at least one classified multidimensional operation data matrix, and generates an output of at least one partial dependency function that explains prediction of the occurrence of the future maintenance message.
