Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a C for visual search.
More specifically, in the case of a CD camera device, a collapsed building at the time of a disaster, a search for survivors such as a house, a narrow place such as a pipe in a construction site where humans are difficult to enter, a dark place or a place with danger, or underwater. It is used for visual search and confirmation, etc., and a camera unit including a small CCD television camera, an illumination lamp, a condenser microphone for sound collection and a microphone / speaker for interrogation is desired via a telescopic gripping bar. The video from the desired search location obtained by the small-sized CCD television camera is visually searched with a television receiver at a desired or remote location by guiding the user to the search location and using the longitudinal motion and the swinging motion. CCD camera device for visual search enabling bidirectional communication between the camera unit and the head set and providing a gas sensor for confirmation About.

[0002]

Conventionally, finding and rescuing victims trapped in buildings, houses, and the like that have collapsed due to an earthquake or the like has been urgently needed, and there is no time to delay. Must be implemented on time.

[0003] However, searchable locations such as collapsed buildings and houses are often narrow places where humans cannot easily enter, or are often dark or dangerous, and it is not easy to visually search and confirm them. In some cases, it is necessary to perform a visual search even underwater.

[0004] Police dogs and disaster rescue dogs, together with trainers, rush to the buildings, houses, etc. and rubble to find people who have been buried or trapped under collapsed buildings, houses, etc., or rubble. Sniff the odor of humans to signal the existence of survivors. However, the number of police dogs and rescue dogs was extremely small, and in the case of a collapse due to a large earthquake, effective detection was almost impossible.

Therefore, the present inventor has already proposed a C for visual search.
Although a CD camera device was proposed, the tip of a telescopic gripping rod to which a camera unit containing a small CCD television camera, illumination lamp, condenser microphone for sound collection, and microphone / speaker for interrogation is fixed is flexible. Therefore, even if the camera section is guided to a required search location, the search cannot be performed effectively.

In addition, since a small CCD television camera and an illumination lamp are built in a curved case of a narrow tip camera section, light of the illumination lamp emits light in the curved case of the camera section. Since the halation is caused by the reflection plate, there is a serious defect that a clear image of a required searched portion cannot be transmitted to the television receiver.

Further, when a known CCD camera device for visual search is used in water, the CCD camera device and the illumination lamp are arranged in separate cases. Because of the need for a shaped container, the overall configuration was necessarily inevitably large.

In addition, in a known visual search CCD camera apparatus, if the camera section is of a waterproof type, the camera section tends to float due to buoyancy when used in water, and it is difficult to operate the camera section. .

[0009]
