The invention relates to a position determining device for determining a position of an elongate object within a tubular structure, said position determining device comprising a first providing unit for providing a first distribution of curvature values at a plurality of first points along a path within the tubular structure. The position determining device further comprises a second providing unit for providing a second distribution of strain values or of curvature values at a plurality of points along the object, and a position determining unit for determining the position of the object relative to the path on the basis of the first and second distributions.

Position determining device for determining the position of an object within a tubular structure

Methods, systems, and techniques are provided to a position determination device for determining a position of an instrument within a tubular structure. The position determination device comprises a first curvature values providing unit for providing first curvature values being indicative of first curvatures of the tubular structure at several first locations along the tubular structure and a second curvature values providing unit for providing second curvature values being indicative of second curvatures of the instrument at several second locations along the instrument. A position determination unit determines the position of the instrument within the tubular structure based on the first and second curvature values.
