Abstract: At a preparatory step for correction, in a state that a reflective tape made with a retroreflective material is pasted in advance onto a floor surface of a measurement space in a direction away from the distance-measuring device, a distance La to an inside area of the reflective tape, and a distance Lb to an outside area of the reflective tape adjacent to the inside area are measured by the distance-measuring device, while measurement positions Y are being scanned along the reflective tape. A correction formula for converting the distance Lb to the distance La is created from a relationship between the distance La and the distance Lb obtained at each measurement position Y. At an actual measurement step, a distance (actual measurement value x) to the target object measured by the distance-measuring device is corrected in accordance with the correction formula, and a measurement-distance corrected value y is calculated.

As an actual measurement step, a distance (actual measurement value x) to the target object 3 measured by the distance measuring device is corrected in accordance with the correction formula, and a measurement-distance corrected value y is calculated.
