A method of registering part of an optical shape sensing system (10) to an imaging system (48) is described, said part comprising a distal multicore optical fiber (16) and a proximal multicore optical fiber (14), an optical connector (34) optically connecting the distal optical fiber (16) and the proximal optical fiber (14) to each other, a launch base (36) fixed with respect to the imaging system (48) and arranged to fix the proximal optical fiber (14). In the method, the shape and orientation of the distal optical fiber (16) and of a section of the proximal fiber (14) extending from the optical connector (34) to the launch base (36) are optically measured for at least two different positions and/or orientations of the optical connector (34) with respect to the object (28). Inter alia based on the optical measurements in the first and second positions or and/orientations of the optical connector (34), said part of the optical shape system as a whole is registered to the imaging system (48). A system for carrying out the method is also described.
