| 摘要 |
The invention relates to a measuring device (1) for measuring the geometry of a hollow cylindrical object (2). Said measuring device (1) comprises at least three interior measuring probes (7) that have outer sensing surfaces (8) to be placed against an inner wall surface (3) of the hollow cylindrical object (2), and at least three exterior measuring probes (7) that have inner sensing surfaces (10) to be placed against an outer wall surface (4) of the hollow cylindrical object (2). Each of the exterior measuring probes (9) is associated with one respective interior measuring probe (7). |
