PROBLEM TO BE SOLVED: To accurately determine the installation or non-installation of a member in a construction site.SOLUTION: In a member installation determination system 1, an observation device 2 photographs a target member 4 in a construction site, captures three-dimensional point group data (the coordinate value of each pixel corresponding to a member), and transmits the data to a server 3. The server 3 receives the three-dimensional point group data from the observation device 2, narrows down the received data according to the design information of the member, and determines the installation or non-installation of the member on the design information based on the point density of the data narrowed down and a distance from the observation device 2. As a coordinate system, an observation device coordinate system (X, Y, Z) specific to each observation device 2, and a field site local coordinate system (x, y, z) specific to a construction site are set. Based on a distance between the observation device 2 and each of two reference points, the position (x, y, z) of the field site local coordinate system of the observation device 2 is calculated. The use of the position of the observation device 2 enables coordinate conversion from the observation device coordinate system to the field site local coordinate system. |
