Abstract
An output device including: a memory; and a processor coupled to the memory, the processor configured to: acquire a satellite image in which a target region is photographed and event information relating to events that have occurred in the target region; and output, from among roads in the target region, a road for which a safety degree calculated based on the satellite image and the event information is less than a threshold value.
Claims5
An output device comprising:
- a memory;
- and
- a processor coupled to the memory, the processor configured to:
- acquire a satellite image in which a target region is photographed and event information relating to events that have occurred in the target region;
- acquire, as the event information, crime information relating to crimes that have occurred in the target region;
- evaluate the acquired satellite image and determine an evaluation value of brightness of a road appearing in the satellite image by:
- extracting road regions from the acquired satellite image by tracking road edges in the acquired satellite image;
- and
- calculating illuminance and brightness-related evaluation values from the extracted road regions;
- evaluate the acquired crime information and determine an evaluation value of the crime information, the evaluation value of the crime information being based on information in the acquired crime information indicating whether or not a crime has occurred and information relating to whether or not a person from whom assistance can be requested when a crime has occurred is present on the road;
- calculate a crime prevention safety degree based on the evaluation value of brightness of the road appearing in the satellite image and the evaluation value of the crime information;
- output, from among roads in the target region, a road for which the calculated crime prevention safety degree is less than a threshold value as an unsafe road;
- and
- cause a warning notification to be displayed on a display of a user terminal, the warning notification instructing the user not to walk on the unsafe road.
