Japanese Unexamined Patent Publication No. 2003-444568

When a building is sold as a second-hand property, it has usually been a long time since the building was built, and some information regarding the investigation and evaluation of the building has been lost or lost. In particular, when the builder and the seller are different, it is often not possible to easily confirm who the builder is. Therefore, it is inefficient to extend or remodel a used building whose structure and building materials used are unknown. In addition, the survey and evaluation value of used properties can be calculated by performing a general depreciation according to the number of years elapsed from the building price at the time of new construction, information obtained by simple preview or external inspection, and other information. Generally, the method of calculation is performed based on the information that can be obtained, and the difference between the assessed value and the actual value has become a problem.

FIG. 8 is a flowchart of the building survey / evaluation system 1. In step S1, the building survey / evaluation system 1 scans the IC tag 1a attached to the building material of the building 1000 by using the methods shown in FIGS. 3 and 4, or uses a normal camera or an x-ray camera. Take a picture of the building. In the next step S2, the scanners 101 and 103 transmit the read information to a calculation means (for example, a CPU or a memory) provided in a predetermined terminal (for example, a smartphone). Further, the image of the exterior of the building by a normal camera and the image by a camera such as x-rays are also transmitted (output) to a predetermined terminal by using a predetermined communication device or an external storage device. In step S2, the calculation means may be a CPU or a memory provided in the server. In the next step S3, the calculation means of the predetermined terminal (for example, CPU or memory) determines whether or not all the information necessary for the investigation or assessment of the building has been read. The determination can be appropriately set on a predetermined terminal. For example, using the information in the database such as the usage, maximum number, and registration examples of other buildings stored in each IC tag 1a, the estimated valuation amount is derived, and the building is 80% or more of the valuation amount. If the material information is obtained, it may be judged that all the information necessary for the building assessment has been read. In that case, the valuation amount finally output may be an estimated amount, and the reliability of the valuation amount may be displayed together with this valuation amount.

In the next step S4, the calculation means (for example, CPU or memory) of the predetermined terminal calculates the survey result / evaluation amount of the building using the obtained information. Specifically, the valuation amount was calculated by depreciating the list price for the number of years elapsed from the list price, taking into consideration the information on the list price, useful life, and manufacturing date of each building material, and calculating the survey / valuation value for each building material. The survey / evaluation value of a building is calculated by taking the total of the survey / evaluation value of each building material. In addition, the survey results are calculated to reproduce the building three-dimensionally by aggregating information such as the dimensions and placement positions of building materials. In the next step S5, as shown in FIGS. 13 and 14, the evaluation value of the building and the survey result are output on the screen of a predetermined terminal. Further, the survey result shown in FIG. 14 displays the building three-dimensionally, and when a building material is specified by a cursor or the like, the registration information of the IC tag 1a attached to the building material is output. In the building survey / evaluation system 1, only the survey result of the building may be output or only the evaluation value of the building may be output. The survey results may include images of the exterior of the building, images such as x-rays, and the like. It is also possible to detect whether or not there is an abnormality in the mounting position or mounting angle of the column or beam by analyzing the image such as x-rays and the information of the IC tag 1a in combination.

The building survey / evaluation system 1 according to this embodiment has the following effects.
(A) Information on the actual building can be obtained by reading the IC tag attached to the building material, and building surveys and evaluations can be performed based on accurate information.
(I) Since a drone is used, it is possible to obtain information on building materials in places where people cannot actually move and access. In addition, accurate information can be obtained using a drone without invading the inside of the building.
(C) Since the IC tag is attached to the building material of the actual building and the predetermined server is not used, any number of people can use the system.
(E) Since the building is displayed three-dimensionally on the screen of the terminal, it is useful when expanding, remodeling or reducing the building.
(O) By taking pictures with a camera such as x-rays, it is possible to check the state of the wood hidden in the wall material and ceiling material.

Next, the building survey / evaluation system 2 according to the present embodiment will be described with reference to FIGS. 9 and 10. The building survey / evaluation system 2 is a system that uses a two-dimensional code 2a instead of the IC tag 1a used in the building survey / evaluation system 1. The two-dimensional code 2a is a code obtained by aggregating the information stored in the IC tag 1a of the building survey / evaluation system 1, and is attached to a part of the building. FIG. 9 shows an example in which the two-dimensional code 2a is attached to the cornerstone plate 200, and the two-dimensional code 2a may be attached to a building structure other than the cornerstone plate. Further, a plurality of two-dimensional codes 2a may be provided depending on the amount of information in the building, or may be newly attached by the contractor each time the building is expanded or remodeled or reduced. The two-dimensional code 2a may include information on the server address for downloading a predetermined application.

FIG. 10 is a flowchart of the building survey / evaluation system 2. In step S10, the building survey / evaluation system 2 scans the two-dimensional code 2a attached to the building using a predetermined terminal (for example, a smartphone). Further, in step S10, the predetermined terminal reads the two-dimensional code (step S11), analyzes the recorded information (step S13), and calculates the assessed amount of the member (building material) (step S15). Execute. In the next step S20, the calculation means of the predetermined terminal (for example, CPU or memory) determines whether or not all the information necessary for the assessment of the building has been read. When all the information necessary for valuing the building is read, the total valuation amount is calculated in the next step S30, and the real estate valuation is output to the screen of the predetermined terminal shown in FIG. 13 in the next step S40.
