The present invention relates to the intervention devices (1020,1120,1220,1320,1420) for the elongation that a kind of processing system (200) can be arranged to enable with optic shape sensing, such as conduit, including optical fiber. The shape data of reconstruction provides the intervention device (1020,1120,1220,1320,1420) that unit (130) provide the shape data of reconstruct. A kind of virtual mark supplier unit (140) provides at least one virtual mark (1020A, 1020B, 1101,1102,1103,1201,1203,1204, (140) 0, (140) 1, (140) 2, shape data based on reconstruct, such as covering to x-ray image. Therefore the present invention rotates any OSS-enabled devices and enters calibrated dial, be suitble to the 3D measurements of various activities.
