PURPOSE:To make it possible to automatically measure three-dimensional matter in a non-contact manner, by relatively driving a detection sensor and the matter to be detected so as to allow the distance between the detection sensor and the matter to be detected to be always present in a definite measurement region. CONSTITUTION:In an apparatus for measuring the shape of matter 1 having a three-dimensional free curved surface, a detection sensor 4 for detecting the distance up to the surface of the matter 1 in a non-contact manner is provided, and the matter 1 and the detection sensor 4 are made relatively movable by a drive apparatus 2. As the detection sensor 4, for example, a laser length measuring machine may be used. The shape of the matter 1 is inputted as a three-dimensional coordinates value in a dot line state by a recording medium 8 and processed by an operational processing apparatus 6 to be applied to the drive apparatus 2 as an order value to perform control so as to allow the detection sensor 4 to be always present in a definite measurable region. |
