PURPOSE:To simplify measurement, by respectively providing movable members and position detection apparatuses on three axes constituting two-dimensional orthogonal coordinates and calculating three-dimensional data on the basis of the rotary angle of a rotary table and the position data of each movable member. CONSTITUTION:Detection rotary encoders 23, 26, 28 are respectively attached to members moving on three axes, that is, an X-axis slide table 22, a Y-axis column 24 and a Z-axis slide box 25, and a measuring probe 29 is provided to the leading end of a Z-axis slide bar 27 in a freely rotatable manner. Further, an article 11 to be measured is vertically grasped on a rotary table 30 equipped with an encoder 32 for detecting a rotary angle alpha and the probe 29 is contacted with two points on the straight line part of the pipe 11 (the article to be measured) and an order button 34 is pushed every time to input positional data of axes X, Y, Z and alpha to a calculator 33 while the vector calculation and crossing point calculation of the straight line part of the pipe are performed by the calculator 33 to obtain three-dimensional data. |
