Problems solved by technology

However, the aircraft ID information cannot be obtained directly from the video, but requires the help of other input sources, resulting in unsatisfactory results
In addition, the accuracy of this type of algorithm depends heavily on the multi-target tracking algorithm. In case of foggy weather, small targets, etc., the aircraft may not be detected, or the false detection may be caused by interference from other factors, which will lead to incorrect listing results. ideal

Embodiment Construction

[0032] Below in conjunction with accompanying drawing, mainly take airliner as example, the present invention will be further described.

[0033] Such as Figure 1-3 As shown, the present invention relates to an aircraft listing method based on the combination of video analysis and positioning information, which needs to complete the acquisition of flight information of known aircraft, the mapping from latitude and longitude coordinates to image coordinates, and the video surveillance system uses multi-target tracking algorithm to detect aircraft The matching of target, latitude and longitude information and the result of target tracking (matching between known aircraft and aircraft target), the overall process is as follows (see figure 1 ):

[0034] Step 1. Obtain flight information

[0035] The flight information mainly includes the aircraft ID (flight number or other identification information), longitude and latitude information of known aircraft, etc., and the flight in...

Abstract

The invention relates to an aircraft listing method based on a combination of video analysis and positioning information. The method comprises the steps of acquiring of information of a known aircraft, video monitoring, target matching, aircraft listing and the like and particularly comprises the steps of converting latitude and longitude coordinates of the known aircraft into coordinates of an image coordinate system, forming a panoramic image according to video monitoring images, carrying out target recognizing and target tracking on the panoramic image by taking the aircraft as the target,recognizing the aircraft target in the panoramic image and matching with the known aircraft to establish a matching or corresponding relationship between the aircraft target and the known aircraft andcarrying out aircraft listing by adopting coordinates, width and height of the aircraft target, which are obtained through the video monitoring, and the flight number of the known aircraft which is matched with the aircraft target. Therefore, the accuracy and the reliability of the aircraft listing are increased and the smooth pursuit effect of the aircraft listing is realized.

Description

technical field [0001] The invention discloses an aircraft listing method based on the combination of video analysis and positioning information, which belongs to the technical field of airport and air traffic management. Background technique [0002] At present, there are two ways to realize the aircraft listing: one is to use the positioning system, such as Automatic Dependent Surveillance-Broadcast (ADS-B) technology to directly obtain the aircraft ID, latitude and longitude information of the aircraft, etc. Aircraft are tagged. The other is to use the panoramic video surveillance system of the flight area, and the multi-target tracking algorithm based on video analysis to identify the aircraft in the video image and list the aircraft. [0003] Among them, Automatic Dependent Surveillance-Broadcast is a method that can automatically obtain relevant information from ADS-B airborne equipment and broadcast the identification number (for example, aircraft ID) and position of...
