<P>PROBLEM TO BE SOLVED: To allow a state (amount of irregularities) of a measurement object surface of a concrete wall or the like to be automatically and accurately measured by an instrument. <P>SOLUTION: A rotating laser measurement instrument includes a distance sensor for measuring a distance by a laser beam, first driving means for driving the distance sensor in an axial direction, second driving means for driving the distance sensor around an axis, and drive control means for controlling drive of the first and second driving means. The distance sensor is supported so as to be rotatable along a surface orthogonal to a lengthwise direction of a measurement object surface and is made movable along the lengthwise direction of the measurement object surface by a prescribed pitch, and a state of the measurement object surface is automatically measured while the distance sensor is moved by the prescribed pitch and is rotated at a prescribed angle. This configuration allows automatic, easy, and accurate measurement of an uneven state and other surface states. <P>COPYRIGHT: (C)2013,JPO&INPIT |
