Description

Field of the Invention [0001] The present invention relates to a method for locating foreign objects in a runway,

The present invention relates to a method for displaying a position of a foreign object in a runway, and automatically generates position information of a detection object such as a foreign object detected by a camera for monitoring foreign objects existing in the runway on the basis of a plurality of reference objects whose coordinates are known, The present invention relates to a method of displaying a position of a foreign object in a runway that enables a field worker to accurately grasp and access the position of the foreign object.

In general, the runway is constantly subject to damage, such as a pit made as a result of wear by an aircraft using the runway or other means of transport, and occasionally a debris or an external object may be present in the runway, / Landing, natural causes, etc. On the actual runway involved in the movement of aircraft, the presence of FOD (Foreign Object Damage) may cause aircraft crashes and resulting human casualties, causing significant losses to the aircraft company.

Thus, runway monitoring is very important in airport operations, and different methods are used to perform runway surveillance. Normally, the surveillance personnel periodically perform visual surveillance with the naked eye as they move near the runway, which is slow, labor-intensive and, furthermore, because the visual surveillance is affected by conditions near the runway, none.

In an automated system using radar, which is used in some airports, microwave signals are typically transmitted over the runway and signals reflected from some other external object are detected and analyzed because the microwave signals are pulsed or structured, Is used to calculate the distance to the external object and higher resolution can be achieved by using a radar sensor with a smaller wavelength and a higher pulse repetition frequency. However, runway monitoring systems using radar have limitations. Radar is an excellent means of detecting metal objects, but it is less sensitive to detecting non-metal objects such as rubber, so that objects made of materials with poor radar signals (eg, rubber) can cause significant problems in radar systems have. Furthermore, limitations such as radar blind spots or shadows are included by obstacles caused by other objects or infrastructures. In addition, radar can cause false alarms by presenting a strong signal to a very small metal object, which may not be so harmful.

Some airports use infrared or thermal imaging systems to detect objects, cracks, and the like on the runway. However, an infrared or thermal-imaging system can only detect infrared radiation (which is emitted from an object), which is outside the thermal equilibrium of the surroundings, that is, an object with sufficient thermal contrast , Pieces of warm metal debris on the cool runway), and small objects with weak thermal contrast can pose serious problems for infrared / thermal imaging systems. Furthermore, such a system is unpredictable under adverse weather conditions (e.g., cold weather).

Recently, surveillance using one or more video cameras located near the runway has been proposed. The video signal obtained from the camera is visually monitored by the operator at the console of the airport control room and a method according to the image processing for detecting any FOD by processing the video images of the runway received from the surveillance camera Has been proposed.

Video cameras used in surveillance systems require additional ancillary illumination (e.g., laser illumination or infrared illumination for night surveillance) and furthermore require significant infrastructure at the airport using such a system, which increases cost . And the presence of optical illumination (e.g., laser illumination or infrared illumination) can interfere with other systems used at the airport, cause safety problems in navigation of the aircraft at the airport, .

Prior art Patent Registration No. 10-1083283 entitled " System and Method for Inspection of Foreign Material and Packing Crack at an Airport "is a terminal of a vehicle that checks foreign matter and packing cracks in real time. By displaying, it is easy to check whether or not the inspection is possible. When foreign matter and packing cracks are found, emergency work items are sent to the terminal of Emergency Repair Personnel at the work site and foreign workers can check the foreign materials and packaging cracks Systems, and methods. ≪ RTI ID = 0.0 >

The camera 110 is composed of a zoom camera of high magnification capable of tilting, rotating, and zooming in / out in order to apply a fixed camera device to a runway etc., And detects foreign objects or the like while being operated by a user's operation while monitoring the runway and transfers the detected foreign objects to the control unit 140. [

The electronic map unit 120 has an electronic map for implementing a runway map, and displays facilities and camera positions on the runway through a separate display (not shown).

The electronic map unit 120 may be driven by the smart device 130 and may implement location information transmitted to the smart device 130 through wired or wireless communication on the display of the smart device 130. [

The smart device 130 is configured to receive the foreign object location information in the process of moving to the destination by the field worker and to receive the map information from the control unit through the wired / do.

The control unit 140 controls the camera 110 to operate by zooming in, rotating, and tilting the camera 110 in the process of detecting the monitored object. The control unit 140 controls the camera (110) The display unit 120 calculates the display position that the camera 110 currently indicated by the camera 110 in the operated state is currently using by using the history of the operation of the display unit 110 and the calculated display position and the position of the detected foreign object Map information, and outputs the map information to the display.

On the other hand, the installation information of the camera includes the installation position and height of the camera 110, azimuth angle, altitude angle, lens magnification, and the like.

In addition, the control unit 140 may display not only the information to which the display position is mapped but also a plurality of reference objects (for example, a pylon, a signboard, a lighting lamp, an induction lamp, a streetlight, etc.) So that foreign object location information is automatically generated based on the reference.

The foreign object location information may include all the angles, directions, distances, and the like from the foreign object to the respective reference objects. In order to facilitate access to the location of the foreign object by the field worker, It is preferable that at least three or more reference objects are included in a plurality of reference objects within a predetermined radius based on the position of the current field worker.
