Construction management system for construction work, program for construction management of construction work, and construction management method for construction work

摘要

PROBLEM TO BE SOLVED: To provide a system for determining whether a construction member has been installed or not, or a process to which a construction member belongs during construction work, based on a three-dimensional coordinate situated on a surface of a construction member or on a surface of a construction member during construction work, at the same time reducing errors in determination results and making recognition possible of an object with an irregular surface also.SOLUTION: With a construction management system 10, an image capture unit 21 captures a three-dimensional coordinate of a surface of a construction member as three-dimensional point group data from a stereo camera 12, a storage unit 23 stores a design three-dimensional coordinate of the surface of the construction member, and a processing unit 22 sets surfaces A, B that face each other with a three-dimensional region that include the three-dimentional coordinate stored by the storage unit 23 in between. Then, the processing unit 22 determines whether the construction member has been installed or not, based on the amount of three-dimensional point group data found in a region between the surfaces A, B.
