PROBLEM TO BE SOLVED: To thoroughly determine an installation and a non-installation of a member in a construction site.SOLUTION: In a member installation determination system 1, a tower crane 5 is installed in a construction site, and includes: a boom 51; a wire 52; and a hook block 53. The hook block 53 is hung with a wire 54 so as to support a hanging balance 55. An observation device 2 is a stereoscopic camera, and is provided on both ends at an underside of the hanging balance 55, images an object member 4 located vertically below, and transmits the imaged image data to a server 3 installed on the tower crane 5. A turning control device 6 is provided in a center of the underside of the hanging balance 55, and causes the hanging balance 55 to turn with a shaft of the hook block 53 as a center. As a result, the observation device 2 is made to turn. A GPS device 7 obtains positional information of the observation device 2. The server 3 receives the image data of the object member 4 from the observation device 2, receives the positional information of the observation device 2 from the GPS device 7, and determines whether or not the object member 4 is installed based on the image data of the object member 4 and the positional information of the observation device 2. |
