PROBLEM TO BE SOLVED: To reduce the cost for the execution of work and to improve the efficiency in the execution of work by two-dimensionally grasping the position and amount of outbreak and contact, and quickly reflecting the tendency of the contact and the outbreak on the execution of work. SOLUTION: A result of the hollow section measurement before the execution, performed by an electro-optical distance meter 5 is displayed by a development, the amount of asperity on the basis of the design section is displayed by contour lines, and a range of each contour line is distinguished from others by using different colors, to display the amount of contact, the amount of outbreak, and the distinction of the contact and the outbreak in the hollow section.
