AI Technical Summary

Technical Problem

Existing construction management systems, such as described in Patent Document 1, do not effectively determine whether managed objects like sleeves are installed according to construction drawings based on information from photographs taken at the actual construction site.

Method used

A construction management device that includes a captured image with measuring members and recognition displays, utilizing a first recognition unit to identify the position of sleeves through orthoimages, and a second recognition unit to determine the coordinates of the sleeves, enabling accurate installation verification.

Benefits of technology

Facilitates easy determination of whether managed objects are installed correctly according to construction drawings, improving construction management efficiency and accuracy.

Abstract

To provide a construction management device that can easily determine whether installation of a management object is performed as in a construction drawing.SOLUTION: A construction management device 100 comprises: a first recognition unit 111 that, on a photographed image including a long-sized member comprising a long-sized body having a predetermined length and at least two recognition displays provided on the long-sized body and associated with different pieces of information, recognizes the recognition displays; and an image creation unit 113 that, based on the recognized recognition displays, creates an ortho-image corresponding to the photographed image. The image creation unit 113 creates the ortho-image by using the coordinates of at least four points included in the recognition displays.SELECTED DRAWING: Figure 6
