FIG. 2 shows that the plane separation diagram (PSD), sidewall photos (WPIC), and matching information (M_I) are directly provided to the 3D drawing generator 130 from the outside of the management server 100, but this The invention is not limited thereto, and the 3D drawing generator 130 may receive a plane separation diagram (PSD), sidewall photos (WPIC), and matching information (M_I) through the communication unit 120.

The 3D drawing generation unit 130 is a plane separation diagram (PSD) in which the plurality of individual spaces included in the facility 11 are separated by the plurality of sidewalls by hand, and the plurality of individual spaces. Based on the sidewall photos (WPIC) photographing the sidewalls to be separated, and matching information (M_I) between the separation lines and the sidewall photos (WPIC) included in the plane separation diagram (PSD), A three-dimensional drawing (3DD) representing a three-dimensional shape may be generated (step S100).

In an embodiment, the standard image database 140 may pre-store a 3D standard sidewall image and a standard member image corresponding to each of the standard members.

In this case, the 3D drawing generation unit 130 generates a 3D drawing (3DD) by using the 3D standard sidewall image stored in the standard image database 140 and the standard member image corresponding to each of the standard members. can do.

Specifically, the 3D drawing generation unit 130 for each of the sidewall pictures WPIC, based on the length measurer 20 included in the sidewall picture WPIC, the actual width and length of the corresponding sidewall SW. You can estimate the length.

For example, since the horizontal reference ruler 21 and the vertical reference ruler 22 included in the length measurer 20 have the reference length, the 3D drawing generation unit 130 Based on the ratio between the horizontal length of (SW) and the length of the horizontal reference ruler 21, the actual horizontal length of the side wall SW is estimated, and the vertical length and vertical length of the side wall SW on the side wall photograph (WPIC) are estimated. The actual vertical length of the side wall SW may be estimated based on the ratio between the lengths of the rulers 22.

Thereafter, the 3D drawing generation unit 130 loads the 3D standard sidewall image from the standard image database 140, and based on the estimated horizontal length and vertical length of the sidewall SW, the 3D standard sidewall image By expanding or reducing the size of the 3D standard sidewall image, a 3D sidewall image having the estimated horizontal length and vertical length may be generated.

In addition, the 3D drawing generator 130 may determine the type of standard member present on the corresponding sidewall SW based on the identification code 31 included in the sidewall picture WPIC.

For example, the 3D drawing generation unit 130 determines whether the identification code 31 is included in the sidewall photo (WPIC), and when the identification code 31 is included, the identification code 31 is By recognition, the type of the standard member indicated by the identification code 31 can be determined.

For example, since the horizontal reference ruler 21 and the vertical reference ruler 22 included in the length measurer 20 have the reference length, the 3D drawing generator 130 uses an image for a sidewall photograph (WPIC). After performing processing to classify the standard member in a side wall photograph (WPIC), based on the ratio between the horizontal length of the standard member and the length of the horizontal reference ruler 21 on the side wall photograph (WPIC), The actual horizontal length may be estimated, and the actual vertical length of the standard member may be estimated based on a ratio between the vertical length of the standard member and the length of the vertical reference ruler 22 on the sidewall photograph (WPIC).

Thereafter, the 3D drawing generation unit 130 loads the standard member image corresponding to the determined type of the standard member from the standard image database 140, and based on the estimated horizontal length and vertical length of the standard member, the The standard member image having the estimated horizontal length and vertical length may be generated by expanding or reducing the standard member image to adjust the size of the standard member image.

Thereafter, the 3D drawing generation unit 130 may insert the size-adjusted standard member image in a position corresponding to the position of the identification code 31 in the 3D sidewall image.

In the same manner as described above, the 3D drawing generation unit 130 may generate the 3D sidewall image in which the standard member image is inserted for each of the sidewall photos WPIC.

Thereafter, the mobile device 200 may correlate the damage coordinate value COOR and the damage information DMI to each other and transmit the on-site inspection result CR to the management server 100 (step S400).

When the on-site inspector finds a plurality of damages in the facility 11, the mobile device 200 generates and generates a field inspection result (CR) for each of the plurality of damages based on the input of the field inspector. The field inspection results (CR) can be transmitted to the management server (100).
