[Prior art]
In recent years, underground malls and large-scale complex commercial buildings are increasing mainly in large cities. Many visitors to such underground malls and buildings can shop and eat while moving within the facility without being exposed to the weather. However, in underground malls and large buildings, you often lose your sense of direction, so you may be wondering where to go. Conventionally, only functional facilities such as “illumination lamps”, “speakers”, “disaster prevention sensors”, “ventilation vents” are provided on the ceiling. For this purpose, a guide map, a place name, character information indicating the name of the building, etc., and a map of the hall including the current location display are posted at predetermined locations in the underground shopping mall and buildings.

An image recording apparatus 3 that outputs information and a plurality of displays 5 that display each piece of image information are provided.
[0015]
The imaging device 1 is a device in which a television camera 8 is installed on an appliance that is installed at predetermined intervals, such as a street light 6 standing near the shoulder of a sidewalk located in the upper part of an underground shopping street. Thus, by attaching the TV camera 8 to the upper part of the street lamp 6, the outdoors can be imaged in a wide range from a high position. Instead of the street lamp 6, it can be installed at a predetermined position on the roof of a plurality of buildings.
[0016]
In the upper part of the underground shopping center, undergrounding of electric wires is promoted, but some of the facilities are on the ground even if they are underground related facilities. For example, as shown in FIG. 3, on-road devices for distribution such as a road transformer 9, a multi-circuit switch 10, a low voltage branch box 11, a high voltage cabinet 12 and the like are installed on the ground. It is also possible to attach the television camera 8 to any one of these on-distribution road devices installed on the ground to form the imaging device 1.

The reason why the fisheye lens 13 is used is that a spherical image captured by the imaging device 1 on the ceiling surface 4 can be displayed on the display 5 of the ceiling surface 4 with a viewing angle of 360 degrees. For people in an underground shopping center or a large complex commercial building, it is possible to recognize the position information of the surroundings around the zenith that is connected to the ceiling surface 4 in the vertical direction from the floor. As shown in the figure, based on a characteristic building, it is possible to easily determine where the person is currently. For example, it can be understood that the north-northeast landscape and the west-southwest landscape are located opposite to each other across the zenith. Therefore, displaying the surrounding (outdoor, outdoor, ground) video on the ceiling surface 4 centered on the zenith makes it easy for the viewer to grasp the position information of 360 degrees in the same visual line direction. become.
[0021]
The television camera 8 is not limited to the fish-eye lens 13 and can be replaced with a wide-angle lens as long as it can capture a wide range of outdoor scenery. For example, when imaging a wide outdoor area with a small number of television cameras 8, it is preferable to use the fisheye lens 13. On the other hand, when the arrangement interval of the imaging device 1 is narrow, it is preferable to use a wide-angle lens. By using the wide-angle lens in this way, an outdoor image can be displayed on the display 5 on the ceiling surface 4 without distortion.
[0022]
The image recording device 3 is a device that outputs already recorded guide image information separately from the outdoor image information captured by the imaging device 1. For example, this guidance image information includes an emergency guidance image displayed on the display 5. This emergency guidance image includes an image that informs pedestrians of the location when a disaster such as a fire occurs in an indoor area such as an underground shopping center or a complex commercial building. Or it can be used to inform the location of the underground shopping center.
[0023]
The image recording device 3 records road guide image information related to the exit to the outdoors. As shown in FIG. 6, this road guide image information includes a method of projecting the position of the exit stairs and the direction of the station every predetermined time when an outdoor image is displayed on the display 5, or the position of the exit stairs, Any method of displaying an image superimposed on an outdoor image so as to display the direction of the station can be adopted.
[0024]
Display device 5, the guidance image information recorded outdoors image information and the image recording apparatus 3 that has been processed by the image processing device 2 is a device for displaying the ceiling surface 4 in the underground shopping center or large complex commercial buildings. The display 5 has a plurality of plasma liquid crystal display devices 14 arranged on the ceiling surface 4. As described above, the display 5 can be divided into a plurality of pieces and displayed in accordance with a wide area such as the ceiling surface 4 of the underground mall or the ceiling surface 4 of the building.
[0025]
The display 5 is not limited to the liquid crystal display device 14, and a projector (not shown) can be disposed as long as it is a means capable of displaying an image on the ceiling surface 4 in a wide range.
