3 D video emergency communication system based on many rotor wing unmanned aerial vehicles
Technical field
The application belongs to communication technical field, specifically, relates to a kind of based on three of many rotor wing unmanned aerial vehiclesDimension video emergency communication system.
Background technology
Along with China's sustained and rapid development of economy, various factors leading to social instability increase day by day, meanwhile,All kinds of natural calamities are also in frequent generation. These accidents, often bring about great losses to social life,Social stability is produced to significant threat. In order to tackle above-mentioned accident, need to be by field condition exactlyConvey to commanding. Traditional mobile communications network, can realize field personnel and command centreBetween voice communication. Be that simple voice communication can not realize completely to emergent on-the-spot complete multipleExisting, can not meet command centre to emergent on-the-spot task deployment, the like this enforcement to emergency disaster relief actionProduce great obstacle. Therefore, we need a kind of emergency communication system, not only can make commander peopleMember's " listening clearly ", can also accomplish " visible ".
In emergency worker does not reach the emergent on-the-spot time period, it is the later stage that emergent site environment is surveyedThe key point that disaster relief operations is implemented. Unmanned plane technology is full-fledged gradually, and unmanned plane carries camera and becomesFor the main way of on-site land survey. Common unmanned plane is divided into fixed-wing, helicopter and many rotors conventionally.Before 10 years, no matter the unmanned plane of fixed-wing and helicopter type is taking photo by plane or model plane Sports Field,Substantially occupy absolute leading position, but along with the raising of taking photo by plane and requiring, fixed-wing, helicopter classThe unmanned plane of type has cruelly spilt a lot of inborn deficiencies in the process of taking photo by plane, such as handling deficiency, spiritActivity is inadequate etc. And many rotor wing unmanned aerial vehicles are in the time that lift-launch camera carries out IMAQ, show exclusiveAdvantage. Many rotor wing unmanned aerial vehicles are to have utilizing radio robot and providing program control for oneself of multiple rotorsThe not manned aircraft that device processed is handled. Many rotor wing unmanned aerial vehicles have good handling, and flexibility is high,Difficulty and the cost of taking photo by plane are greatly reduced. Adopt the conduct of many rotor wing unmanned aerial vehicles for emergency communication systemCamera carrying platform has highlighted exclusive advantage.
The image effect collection of image often being obtained by traditional technology is all two-dimentional plane effect,Two dimensional image is when to emergent on-the-spot reduction, and just a plane is shown. Commanding is according to obtain twoDimension image is difficult to the emergent scene of rediscover.
