Abstract: Even an attribute of a target object can be clearly confirmed while looking at a photographed image. According to one embodiment, where the user sets additional information for a 3D display image, a user terminal MT first displays first guide pattern in the process of specifying a setting target of the additional information, and then displays second guide information in the process of specifying the display position of the additional information. After the display position is determined, the additional information input by the user is registered in a server device SV in association with the setting target and the coordinates of the display position.

Abstract: Image information appropriately representing the state of changes in the three-dimensional space is generated. According to one embodiment, a server device (SV) stores, in an omnidirectional image storage unit (21), omnidirectional images of a three-dimensional space photographed at a plurality of positions, for each floor of a facility. Where two images of the same floor photographed at different dates and times are displayed for comparison, an omnidirectional image whose photography position coordinates are closest to the photography position coordinates of a comparison reference image is selected from among all omnidirectional images to be compared. The angle of the selected omnidirectional image to be compared is adjusted such that it corresponds to the angle of a comparison reference image. Comparison display image data is generated in which the adjusted comparison image and the comparison reference image are arranged side by side and is transmitted to the user terminal (UT1).
