Abstract
Provided is an elevator shaft dimensions measurement device including: a plurality of 3-D distance image sensors which are arranged on a circumference of the same circle, facing the direction of the center of the circle and inclined at an elevation angle with respect to a horizontal plane, and which output measurement data by capturing an image of a pattern irradiated onto the inner walls of an elevator shaft that are imaging objects; and a computer which integrates the measurement data output from the plurality of 3-D distance image sensors at a plurality of height positions in the elevator shaft, generates first integrated measurement data covering 360 degrees in the horizontal direction, aligns the first integrated measurement data to create second integrated measurement data after the alignment, and calculates the dimensions of the elevator shaft on the basis of the second integrated measurement data after the alignment.
