PURPOSE: To correct error when a shape steel is dislocatedly or obliquely transported on the way of transport, and measure bending of the full length and a local part, by measuring the shape steel by means of three distance measuring instruments provided on the side of a transporting table, and measuring a transport speed by means of a speed meter. CONSTITUTION: Three distance measuring instruments 1, 2, 3 are installed in the lengthwise direction on the side of a table 7 transporting a shape steel 6 in the lengthwise-direction, so as to measure the distances to the shape steel 6. Further, a transporting speed of the shape steel 6 is measured by means of a speed meter 4, and positions where the distances are measured by the distance measuring instruments 1, 2, 3 are computed by a computer 5. By this measurement, three coordinates are introduced on many positions of one shape steel 6. The computer 5 computes from the coordinates, and bending quantities on the full length, the end part, and the local part can be simultaneously measured. For the distance measuring instruments, an optical range finder or a laser type range finder are generally used, and for the speed meter 4, a Doppler type speed meter directly measuring transport speed is generally used.
