Method for determining a track of a geographical trajectory

Abstract

A method for determining a track of a geographical trajectory which has a predetermined start location and a predetermined end location, said method comprising the steps of: moving a data collecting device from the start location to the end location, the device comprising a set of sensors providing for sample wise collection physical measurement data during the movement of the device and enabling the determination of a heading profile, a pitch profile, a distance profile and a roll profile from said measurement data; determining said heading profile, said pitch profile, said distance profile and said roll profile based on the collected measurement data; and determining said track based on said heading profile, said pitch profile, said distance profile and said roll profile. All said physical measurement data are stored during the movement of the device from the start location to the end location. After retrieval of the stored measurement data and before determining said profiles, the method further comprises the steps of: determining at least first, respectively second trajectory parameters based on measurement data of a first, respectively second sensor of said set and mapping said first trajectory parameters on said second trajectory parameters; determining an error compensation for said measurement data of said first and said second sensors based on said mapping; and correcting said measurement data of said first and second sensors by means of said error compensation.
