A disaster prevention system 100 according to the second embodiment will be described with reference to FIG. FIG. 4 is a schematic diagram illustrating the disaster prevention system 100 according to the second embodiment.

The disaster prevention system 100 includes a lighting system 1 and an information processing device 101 . The lighting system 1 and the information processing device 101 are connected via a network N by wire or wirelessly so that they can communicate with each other.

The information processing device 101 is, for example, a server device. The information processing device 101 transmits disaster occurrence information to the lighting system 1 when a disaster occurs. The disaster occurrence information is information that notifies the occurrence of a disaster that requires evacuation from the facility. The information processing device 101 also receives vehicle position information from the lighting system 1 .

Vehicle location information is collected from vehicles parked in a facility's indoor parking lot that have a passenger on board and that have a mark indicating that they are boarding a disabled vehicle (hereinafter referred to as "specific vehicle"). ) is position information. A parking section is a section set in advance in a parking lot, and is a parking range (parking space) for one vehicle. Parking lots are demarcated, for example, by white lines.

The information processing device 101 transmits vehicle position information to, for example, a security guard's receiving device when a disaster occurs.

The acquisition unit 35 acquires disaster occurrence information from the information processing device 101 .

The analysis unit 36 determines whether or not disaster occurrence information has been acquired. The analysis unit 36 detects whether or not a disaster has occurred based on the disaster occurrence information. When the disaster occurrence information is acquired, the analysis unit 36 determines whether or not the specific vehicle has been detected. The analysis unit 36 detects the presence or absence of a specific vehicle.

The analysis unit 36 performs image processing on the image data acquired by the acquisition unit 35 and detects the presence or absence of a vehicle in the parking space. Specifically, the analysis unit 36 detects parking spaces from the acquired image data.

The analysis unit 36 detects, for example, a parking space by extracting a line indicating the parking space. The analysis unit 36 sets the area corresponding to the parking space as the detection area. Note that the detection area may be set in advance for the image data. Then, the analysis unit 36 detects the presence or absence of the vehicle in the parking space based on the degree of detection of the road surface in the detection area. For example, the analysis unit 36 detects the presence or absence of a vehicle in a parking space from the difference image data between the image when the vehicle is not parked and the captured image.

When a vehicle is present in the parking space, the road surface in the detection area is blocked by the vehicle. Therefore, the detection degree of the road surface in the detection area is lowered. The analysis unit 36 calculates the degree of detection of the road surface in the detection area and calculates the occupancy rate. The occupancy rate is "0%" when the entire road surface in the detection area is visible. The analysis unit 36 determines that the vehicle is parked in the parking space when the occupancy rate is equal to or greater than the predetermined occupancy rate. The predetermined occupancy rate is a preset value, for example, "70%". The presence or absence of a vehicle in the parking space may be detected by an infrared sensor or the like.

Also, the analysis unit 36 detects the presence or absence of a passenger in the vehicle parked in the parking space. The analysis unit 36 detects the presence or absence of a passenger in the vehicle, for example, by performing face authentication processing on the acquired image data.

In addition, the analysis unit 36 detects whether or not a vehicle parked in a parking space has a mark (for example, a four-leaf mark) indicating that a physically handicapped person is on board. For example, the analysis unit 36 performs pattern matching processing on the acquired image data to detect the presence or absence of a mark indicating that a physically handicapped person has boarded the vehicle.

The generation unit 37 generates evacuation route information when disaster occurrence information (hereinafter referred to as “first disaster occurrence information”) is acquired. Note that, as in the first embodiment, the generating unit 37 generates information for controlling the lighting states of the first lighting unit 11 and the second lighting unit 21 of the first lighting device 10 . 2 Generated as disaster occurrence information (hereinafter referred to as “second disaster occurrence information”) to be transmitted to the lighting unit 21 . The generated evacuation route information and second disaster occurrence information are transmitted to the first lighting unit 11 of the first lighting device 10 and the second lighting unit 21 of the second lighting device 20 via the communication unit 31. .
