Measuring device for elevator shaft dimensions and measuring methods for elevator shaft dimensions

摘要

The present invention relates to a hoistway dimension measuring apparatus comprising: a plurality of 3-D distance image sensors arranged on a circumference of the same circle, oriented toward the center of the circle and inclined at an elevation angle with respect to a horizontal plane, and output the measurement data that is emitted by picking up an image of a pattern that is on the inner walls of a hoistway, the imaging objects; and a computer that 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 a range of 360 degrees in the horizontal direction, balances the first integrated measurement data, and second integrated measurement data after the match, and calculates the dimensions of the elevator shaft based on the second integrated measurement data after the match.
