Description

Real time multi-media data delivery method and apparatus on internet or intranet using unmanned camera}

The present invention relates to a method and a system for transmitting real-time image information of the Internet or an intranet using an unmanned aerial photographing apparatus, and more particularly, to a photographing monitoring and retrieval system in a specific field by combining an unmanned aerial photographing apparatus and the Internet or an intranet. The present invention relates to a method and system for transmitting real-time image information of the Internet or an intranet using an unmanned aerial photographing apparatus that can be easily implemented.

Recently, with the spread of personal computers, high-speed modems, and leased lines, multimedia data transmission has become possible, resulting in the convergence of broadcasting and communication.

That is, in the conventional broadcasting system, the service is mainly focused on a service for transmitting the same contents to a plurality of unspecified viewers, and the user has no choice but to continuously watch the broadcast in order to continuously know the contents or information necessary for the viewer.

However, Internet broadcasting is a two-way service system that can receive a channel consisting of the contents desired by the user as well as the broadcast time zone without the limitation of time and space, and can freely exchange various multimedia contents based on the multimedia technology combined with the computer. Is applied.

For this reason, various fields of Internet broadcasting are under development, and the present invention belongs to the field of acquiring and transmitting real-time image information of the Internet or intranet applied to live broadcasting.

The development level of the conventional Internet real-time video information transmission system, especially the network for sharing real-time video information of a specific field is poor.

For this reason, since the Internet broadcasting system also started from imitation of the existing broadcasting system, it is necessary to secure broadcasting data in order to implement the broadcasting system. The biggest problem is the need for large input resources and equipment such as shooting equipment and manpower. .

In other words, in a broadcasting system, a broadcast station transmitting an existing broadcast, an internet broadcast or a broadcast, a medium relaying the broadcast broadcast, and a receiver receiving the broadcast are similar to each other. Among them, the transmission medium is airwaves and the Internet, and the receiver is a television. Is different from a computer (browser).

In this case, the Internet broadcasting is mainly used as a means for transmitting information to the Internet, and a software means interworking with the server is mainly used. Therefore, it can be compared with the existing hardware broadcasting system as a means for connecting and implementing a broadcasting station and a transmission medium. The input resources are simple and economical.

In addition, the existing broadcast is mainly focused on a system that transmits the same content to multiple viewers, so there is no concern for small groups or individuals, but the broadcasting through the Internet enables two-way transmission for small groups or individuals.

However, the problem is the acquisition of real-time transmission data and the poor performance of the photographing equipment.

For this reason, it was inevitable to use the webcam used for video communication to reveal personal information or to ignore small-scale broadcasting that ignores copyrights and edits and distributes others' works. The concentration of development in large corporations is an unavoidable reality.

In particular, the development of specific fields in the intranet is very poor.

In other words, if you use an intranet, which is a network system that allows information from internal organizations of specific organizations to share the necessary information by building an information sharing system using the World Wide Web (WWW) and browser software technology, It is possible to build a system.

Therefore, it is possible to build a system for the public on the intranet such as a disaster detection, rescue search system or security security search system that requires real-time image information.

However, the biggest problem here is the acquisition of real-time image information, and if this is not solved, it is difficult to implement a real-time image information transmission system for a specific field such as the public interest.

Accordingly, the present invention has been made to solve the above problems, using an unmanned aerial control device such as an unmanned aerial vehicle or unmanned controlled submarine with a wireless camera, in particular, unmanned pilot that can be applied to real-time image information transmission in a particular field An object of the present invention is to provide a method and system for transmitting real-time image information of the Internet or intranet using a photographing apparatus.

To this end, the present invention is provided with an unmanned pilot camera equipped with an unmanned aerial camera for transmitting image information in real time, an image receiver for receiving an image from the unmanned aerial camera in real time, and real time continuous information transmitted from the image receiver. It consists of an encoder for processing the server and a server for transmitting the real-time continuous information processed from the encoder to the browser on the Internet or intranet upon user's request.

According to the present invention, the real-time video information is required in a specific field for public interest, for example, security search or tracking for security, video evidence acquisition, disaster situation search or escape search for rescue, or military search. It is possible to build an intranet and to build Internet for news and traffic broadcasting for the general class.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a block diagram according to the present invention, the present invention comprises a step 1 of photographing the image with the unmanned operation camera equipped with an unmanned control camera 10: the real-time image photographed in the step 1 receiver 12 Step 2 of digitally converting and compressing the digitized real-time continuous information, if necessary, by the encoder 14; and requesting a user on the Internet or an intranet through the server 16 through the real-time continuous information processed in the above step 2). Real-time image information transmission method using an unmanned aerial shooting device consisting of three steps to transmit to the user's browser (18).

In addition, the present invention according to the above is equipped with an unmanned control camera and outputting the image information in real time 10 and a receiver 12 for receiving in real time the image from the unmanned aerial shooting device 10 ), An encoder 14 for processing real-time continuous information sent from the receiver 12, and a server 16 for transmitting real-time continuous information processed from the encoder 14 to a browser on the Internet or an intranet upon a user's request. It is a real-time image information transmission system using an unmanned aerial photographing device consisting of.

As described above, the present invention provides real-time image information required by the consumer using the unmanned aerial imaging apparatus 10.

The unmanned aerial control apparatus 10 refers to various unmanned aerial vehicle transport equipment equipped with an unmanned aerial vehicle, and may include, for example, an unmanned aerial helicopter, an apparatus, a submersible, and the like, and in particular, a separate monitor 20 as a photographing equipment in the helicopter. Through unmanned operation by wireless, the control radius is close to 10km and is commercially available in Korea.

The applicant also has an unmanned aerial vehicle (application number: 10-2000-0025803, 10-2000-0024365, 20-2000-0013865, 20-2000-0013479, 30-2000-0014576) or submersible (application number: 10- 2000-0029862, 20-2000-0014181) has been applied for a number of devices, when using the unmanned aerial photographing device 10, a high-level camera that could not be obtained while controlling the camera directly by the operator's manual work Angle and precise image information can be obtained.

To describe this in more detail, subject shooting on a flat surface is limited in angle.

Therefore, a rail or a crane is used as a peripheral device of the camera in order to control a variety of camera angles.

At this time, the installation of such a rail or crane itself requires too much quantity and manpower, and also due to the constraints of space, it is inevitable to rely on aerial photography in areas where installation of such a rail or crane is difficult.

In this case, the equipment and manpower required for aerial photography are enormous, and the air navigation procedures are difficult.

For this reason, it is practically difficult to obtain enough images in a small Internet broadcast, especially in real-time video transmission, which is a level of flat shooting or a simple webcam as described above.

In addition, when the operator directly controls the camera, it is difficult to photograph a dangerous area such as a contaminated area or a disaster area, and real time broadcasting thereof is more difficult.

The present invention improves this problem through the unmanned aerial vehicle 10 and the Internet or intranet.

Naturally, the web page is configured in the real-time video transmission system having the unmanned aerial recording apparatus 10, except for the client side, the real-time video transmission side and the encoder 14 side through the unmanned aerial recording apparatus 10 are large. And it is classified on the server 16 side.

The real-time image transmitting side is composed of an unmanned aerial control apparatus 10 equipped with an unmanned aerial camera, a receiver, and a repeater 11 for transmitting real-time image information transmitted to the receiver 12 by airwaves.

On the encoder 14 side, the image obtained from the unmanned aerial imaging apparatus 10 is transmitted to the receiver through the repeater, and the transmitted real-time continuous information is converted into a digital signal through the encoder 14 and compressed for real-time transmission. Is performed.

On the other hand, if the present invention is applied to the wireless Internet system that is being developed enthusiastically, the receiver 12 and the repeater 11 and the like described above will not be necessary.

In other words, if a wireless Internet system using a satellite network is used, the encoder 14 may work on the image information captured by the unmanned aerial imaging apparatus 10 and transmit the image information to the server 16 at the position.

The encoder 14 is software for real time continuous information compression transmission, and not any one specific software is applied to the present invention.

The encoder can either deliver audio and video content to the server or encode it into an ASF stream used for asf files, the output of which can be listened to or viewed in real-time software (hereinafter referred to as the player) and for server multicast, unicast or storage. An information stream that can be sent to.

Here, encoding and compression of video and audio content requires high processing power of a computer, so it is preferable to perform encoding on a separate computer.

The server 16 includes a web-based management application for interfacing with the client side and the web server to monitor real-time usage, manage content, and configure the system, and store the real-time image information compressed by the encoder 14 on the Internet or the Internet. It means a streaming server that transmits on an intranet.

The web server only provides the location information of the streaming server, which requires real-time multimedia homepage management and location information on the multimedia data.

The software on the server 16 side is not limited to any one specific software, and the general real time transmission of the server 16 at the request of the user will be described as follows.

When a user visits a web server on the Internet or an intranet and clicks the location information of the real-time image data captured by the unmanned aerial imaging apparatus 10, the web server transmits the location information of the multimedia data to the user's browser 18.

The user's browser 18 executes the player and transmits the location information of the real-time image data to the player.

At this time, the player reads the location information and requests the server to transmit the data converted and digitally converted by the unmanned aerial imaging apparatus 10 in real time, and the server transmits the requested data to the real player in real time.

The present invention is limited to the transmission of real-time image information using the unmanned aerial imaging apparatus 10, and the present invention is excellent for application in a specific field.

In other words, examples of specific fields requiring real-time video information transmission include security, disaster surveillance, military search, and news.

For example, no matter how complex the downtown area, such unmanned aerial photography 10 can be quickly dispatched, tracked and repeated monitoring, and can be used as evidence for crime because it can store the image information if necessary. .

In such a case, if an intranet that operates a web page in a closed manner in consideration of the network line speed of the server 16 is used, it can be professionally used in a specific field, for example, a police or security company.

In addition, even if openly operated on the Internet, it is possible to give the netizens, the unspecified majority, the role of a security watcher, and for the same reason it can be used for military search.

In particular, since the present invention is useful for disaster search and the unmanned aerial vehicle shooting apparatus 10 can access a dangerous area that is difficult for humans to access, in a specific field of rescue organizations, such as disaster situation search, requestor search, escape route search, etc. It can be used.

On the other hand, the Internet application of the present invention for the general class may include, for example, news and traffic broadcasting.

In the live news broadcasting, detailed image information transmission is possible because aerial or underwater photography in a complicated and dangerous area is possible by using the unmanned aerial shooting apparatus 10 as described above.

In addition, even in traffic broadcasting where real-time information is required, the present invention avoids the level of a webcam in a fixed place.

That is, the conventional application to traffic broadcasting stays at the level of a webcam that transmits the traffic of a specific area by installing a camera on a pier or a building.

However, when the present invention is used, the traffic survey section is divided into a plurality of sections by using the unmanned pilot vehicle, and the detailed operation volume information can be obtained by repeatedly operating the unmanned pilot vehicle equipped with the unmanned aerial camera for each divided section. Can be.

Here, the unmanned control mechanism is a power device is provided in the streamlined body of the body filled with helium gas, etc., and is used for advertising in recent years.

Therefore, as described above, the present invention enables the realization of a system for the field that requires real-time image information by organically combining the unmanned aerial imaging apparatus 10 and the Internet or an intranet.

As described above, it is easy to implement a surveillance and retrieval system in a specific field by combining an unmanned aerial imaging apparatus with the Internet or an intranet, and thus, in the field where real time image information is required, It is easy to implement the acquisition and transmission system.
