Embodiment 1

[0040] This embodiment is based on the following ideas:

[0041] First of all, the aircraft targets in the apron area are large, and there are high pole lights at night, so the light is ideal; in addition, the apron is a strictly controlled area, and there is no interference from unrelated vehicles and personnel. Based on the above reasons, using the intelligent video analysis technology in the prior art, it is possible to accurately locate and identify the aircraft in the apron area.

[0042] Then, after locating the exact position of the aircraft in the apron area in the image, use measurement and coordinate conversion to convert the pixel coordinates in the image into latitude and longitude coordinates, which are used as a new data source for integrated track data , which is used to improve the accuracy of the comprehensive track data in the apron.

[0043] refer to figure 1 , figure 1 A flow chart of the steps of the method for improving the accuracy of the comprehensiv...

Embodiment 2

[0081] This embodiment is the optimization method of Embodiment 1, specifically:

[0082] Embodiment 1 mainly uses intelligent video analysis to obtain the exact position of the target, and then uses the transformation from pixel coordinates to latitude and longitude coordinates to realize the output of the latitude and longitude position of the apron target, thereby increasing the data source of the integrated track monitoring system. It can effectively overcome the shortcomings of the existing ads-b, multipoint positioning and surface surveillance radar systems in the integrated track system in the apron area, and improve the accuracy of the integrated track data. In the transformation from pixel coordinates to latitude and longitude coordinates, RTK equipment is used to measure points in the apron area, so as to obtain a series of point pairs corresponding to latitude and longitude coordinates and pixel coordinates, and then use the algorithm in step 230 to improve calculati...

Embodiment 3

[0129] The present invention also provides a device for improving the accuracy of the comprehensive track monitoring data of the apron, comprising:

[0130] The detection and identification module 40 is used to obtain the pixel coordinates of the aircraft in the apron area in the video image based on intelligent video analysis;

[0131] The coordinate conversion module 42 is used to convert the pixel coordinates of the aircraft in the video image into the latitude and longitude coordinates used by the track monitoring system;

[0132] The data fusion module 44 is used for connecting the latitude and longitude coordinates to the existing track data for data fusion to obtain comprehensive track data, and based on the comprehensive track data, real-time monitoring of aircraft in the apron.

[0133] In the following, the above three modules will be described one by one.

[0134] First, the identification module 40 is detected. This module is used to obtain the pixel coordinates ...

The present invention provides a method, device and system for improving the accuracy of airfield integrated flight track monitoring data. The method includes, based on intelligent video analysis, obtaining the pixel coordinates of aircraft in the airfield area in the video image; determining the pixel coordinates and latitude and longitude Coordinate conversion relationship; convert the pixel coordinates of the aircraft in the video image into the latitude and longitude coordinates used by the track monitoring system; connect the latitude and longitude coordinates to the existing track data for data fusion, and obtain comprehensive track data, based on the integrated track Data, real-time monitoring of aircraft on the apron. The present invention proposes the method of approximate planar mapping and double-sided mapping to realize the efficient and accurate conversion of pixel coordinates to longitude and latitude coordinates, realize the precise conversion of the pixel coordinates of the aircraft in the video image into the longitude and latitude coordinates used by the track monitoring system, and improve the The accuracy of the longitude and latitude coordinate data is improved, and the accuracy of the comprehensive track data in the apron is effectively improved.

Description

technical field [0001] The invention relates to the technical field of civil aviation, in particular to a method, a device and a system for improving the accuracy of apron comprehensive track monitoring data. Background technique [0002] The most commonly used monitoring method in civil aviation airports is to use integrated track data for real-time display. The integrated track data is integrated with various airport monitoring systems, such as ADS-B, multi-point positioning, surface surveillance radar, A-CDM, etc., in order to achieve more Rich data display and higher monitoring accuracy. [0003] In actual use, there are some limitations in the integrated track access data, especially for the apron area. For example, the signal coverage of ADS-B on the apron is not good, and the problem of target loss often occurs; The positioning accuracy of the apron is not enough. The European Air Traffic Network Management Organization (EUROCONTROL) has given the accuracy standard o...
