Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device inside a structure or a vehicle, which can constantly monitor all directions of 360 °.

[0002]

2. Description of the Related Art A television camera or an optical device is used as a device for an operator inside a building or a vehicle to monitor the outside. As a means for monitoring all directions of 360 °, for example, a television camera that turns by remote control can be mounted on the structure, and the information sent from the television camera can be displayed on a CRT display and monitored. Also, in closed ships such as submarines, periscopes are equipped to optically monitor all directions.
In an apparatus equipped with a pivoting TV camera, an operator points the TV camera in a desired direction by remote control, and obtains an image of the outside world in that direction. If the TV camera has a zoom function, the function can be used to enlarge and monitor the image.

However, since the viewing angle of the television camera is limited, it is only possible to obtain images of only a part of the external world, and it is not possible to monitor the images of the remaining directions. It takes a certain amount of time to rotate the television camera to change the azimuth to be monitored. Moreover, it is difficult for the operator to instantaneously confirm the orientation of the image on the current CRT display. In an optical device such as a periscope, the operator faces the direction of the optical axis of the lens, so
It is possible to easily recognize the direction currently monitored.
However, it is difficult for a person other than the operator who operates the periscope to simultaneously recognize the azimuth information and the appearance of the outside world. In addition, turning the periscope to monitor another direction requires a turning time, and the direction to be monitored cannot be instantaneously changed.

[0004]

As means for constantly monitoring all directions of the outside world from the inside of a closed area surrounded by a partition wall,
For example, a plurality of TV cameras are prepared, and the TV cameras are radially arranged so as to cover the viewing angle of 360 °, and the CRT displays connected to the TV cameras are arranged inward on the circumference. And then CR
There is a means for the operator to enter and monitor inside the ring of the T display. However, also in this case, among the CRT display groups arranged inward on the circumference, there is a physical gap between adjacent displays.
Then, the image in the gap will be displayed on the adjacent display, but it is difficult to instantaneously recognize the accurate direction, and when instantaneous judgment is required, there is a problem that the judgment is dull. Occurs. The present invention provides an omnidirectional monitoring device that solves the above problems.

[0005]

An omnidirectional monitoring device according to the present invention includes a plurality of television cameras arranged outside a partition wall to photograph omnidirectional images, and an image display device for displaying images photographed by the television camera. The image display device includes a sensor that detects a direction in which the image display device is facing, and a control device that displays a captured image of the outside world corresponding to the direction in which the image display device is facing, on the image display device according to a signal from the sensor.

[0006]

[Operation] Since the operator wearing an image display device such as an eyephone monitors the external image corresponding to the direction of the face,
All directions can be monitored without misidentifying the direction of the outside world being monitored.
