In the case of field images for which the location of the disaster area is unknown, the location can be estimated with street address-level accuracy and then by comparing the images with aerial imagery and map data covering wider areas can be displayed on the map.

Field images provided in emergency situations such as disasters do not necessarily include location information, which can sometimes make it difficult to identify disaster areas. While NEC has developed techniques in the past to estimate locations through the use of satellite images and aerial photographs (*1), this latest technology has achieved the world’s highest matching accuracy (*2) (*3) , allowing the location to be estimated with a high degree of accuracy. degree of precision, even for field images taken during a disaster.

To estimate locations, this technology automatically extracts regions such as roads, buildings and traffic signs from field images and then combines them with map layout information (the size and layout of roads, buildings, etc.). In this way, even for images of partially collapsed buildings or partially flooded streets, the photographed location can be updated by actively using information on roads and buildings at low risk of damage in the event of an earthquake. Highly accurate estimation becomes possible. Reduced risk of drowning in flood conditions to match.

NEC plans to put this newly developed technology into practical use within FY2025 in an effort to help expedite evacuation guidance, rescue efforts and other early response activities in the event of a disaster. In addition, NEC is committed to making society safer, more secure and more convenient by expanding the use of LLM and image analysis technology in other applications.
