Abstract
Method for inside-out optical-inertial tracking of a movable object includes providing IR light by a plurality of markers; reading a picture from an optical sensor and detecting pixels satisfying predefined conditions by a first data processing device; detecting marker blobs, based on the pixels, and determining parameters of the blobs by the first data processing device; reading data from an inertial sensor; generating a consolidated data flow comprising the parameters of the marker blobs and the data of the inertial sensor by the first data processing device, and transmitting the data flow to a second communication device; determining a tracker positioning data in a coordinate system of a motion area of the object, based on the consolidated data flow, by a second data processing device; validating a model of a tracker motion path, based on tracker positioning data; extrapolating tracker positioning data onto an extrapolation horizon, based on the model.
