AI Technical Summary
Technical Problem
Existing systems cannot investigate the flooding situation of a building in real-time while it is submerged, as they require on-site imaging after flooding has subsided.
Method used
A flooding situation survey system with a shooting device and processing device that captures and processes images of a building's predetermined part before and during flooding, calculating the distance to the water surface using pixel lengths and image corrections, allowing for real-time remote monitoring.
Benefits of technology
Enables easy and accurate remote investigation of flooding situations by calculating flood depths and changes over time, facilitating timely decision-making and repair planning without on-site visits.

Abstract
To more easily investigate the extent of flooding in a building while it is submerged. [Solution] The flooding situation survey system S1 of the present invention comprises a shooting device 40 and a processing device 10 that acquires an image of the building's entrance door from the captured image. The processing device 10 performs a non-flooding process using a first image showing the entrance door in a non-flooded state, and a flooding process using a second image showing the entrance door in a flooded state. In the non-flooding process, the unit pixel length is determined based on the number of pixels from the bottom end to the top end of the entrance door in the first image and the actual length from the bottom end to the top end of the entrance door. In the flooding process, the position of the water surface at the entrance door is identified in the second image. Based on the first and second images, a corresponding position corresponding to the bottom end of the entrance door is identified in the second image, and the flood depth is calculated based on the number of pixels from the corresponding position to the water surface in the second image and the unit pixel length.
