Data integration apparatus, method and program

Abstract

The present invention provides a data integration apparatus, method, and program that can accurately integrate three-dimensional data in a hoistway measured at a plurality of locations with high reliability. In the data integration apparatus, method, and program for integrating measurement data measured by using three-dimensional measuring devices at a plurality of positions in an elevator hoistway, for measurement data obtained by measurement on the upper side of a car, position alignment in the height direction is performed by adopting the ceiling of the hoistway as a datum and position alignment in the horizontal direction is performed by adopting a guide rail as a datum; and for measurement data obtained by measurement on the upper side of the car and the measurement data obtained by measurement in the lower side of the car, position alignment in the height direction is performed by adopting a common component as a datum and position alignment in the horizontal direction is performed by adopting the guide rail as a datum.

Description

technical field [0001] The present invention relates to a data integration device, method, and program, and is applicable to, for example, a data integration device that integrates 3-dimensional measurement point group data obtained at multiple places in an elevator hoistway. Background technique [0002] When refurbishing an elevator, the dimensions of various parts in the hoistway are collected for comparison with the dimensions of the new car. Conventionally, the dimensions of each part in such a hoistway have been collected manually. [0003] However, in recent years, a method of measuring the dimensions of various parts in the hoistway using a three-dimensional laser measuring device has been considered. This method uses a 3-dimensional laser measuring device at multiple height positions in the well to measure the 3-dimensional coordinates of multiple places on the surface of the structures in the well (the inner wall of the well, beams, columns, guide rails, etc.), an...

Problems solved by technology

[0006] In this case, in Patent Document 1, feature parts suitable for positional alignment are extracted, and the three-dimensional point cloud position data of the measurement object observed from the first viewpoint is compared with the measurement object observed from the second viewpoint. The positional alignment of the 3D point group position data, but for example, when the alignment is performed in the hoistway with the wall of the hoistway as one of the common parts as a reference, the positional alignment can be performed in the horizontal direction of the x-axis and the y-axis, but There is a problem that positional deviation occurs in the z-axis direction (height direction), and it cannot cope with the deterioration of the accuracy of data integration.
