Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] The invention discloses an airport foreign object (FOD) detection method based on a dome camera monitoring video. In the method, video signals are collected by a monitoring dome camera set up in a specified area of ​​the airport, and video signals of sub-regions are polled sequentially through the rotation of the dome machine. After the video is decoded, the computer vision and image processing technology are used to update the background of the video in each sub-area and perform polling detection covering the entire area. Combined with the residence time of the suspected objects, it can be judged that various types of FOD with a diameter of 2cm-50cm in each sub-area, According to the sub-area of ​​the image and the matching of common FODs, the location area of ​​the FOD, the possible target type and other information are obtained, and the obtained information i...

Abstract

This invention discloses a method for detecting airport foreign object debris (FOD) based on a monitoring video of a dome camera. The method comprises the following steps: step 1, initializing; evenly dividing a to-be-detected area into several subareas to enable the union set of the subareas to completely cover the to-be-detected area; step 2, extracting a background; decoding collected video signals by a processing unitand then modeling through a time averaging method; step 3, extracting a foreground and performing a polling detection; step 4, judging after performing the polling detection; and step 5, saving an evidence; transferring data of a target location range of the FOD, extracting time data and extracted target information image data to a rear control and dispatching center through a network to enable the dispatching center to make a relevant decision. The method provided by theinvention has a strong ability for resisting ambient noises and reliably works.

Description

technical field [0001] The invention belongs to the field of digital image processing and the technical field of intelligent video monitoring, and specifically relates to a foreign object (FOD) detection method at an airport based on a dome camera monitoring video. Background technique [0002] Because foreign objects (FOD) on the airport runway are very harmful to the safety of aircraft take-off and landing, with the development of science and technology, the advancement of computer networks, image processing and other technologies, real-time and automatic detection of foreign objects has become possible, and the detection height has been realized. Intelligent, make full and reasonable use of the limited runway inspection time, reduce the burden on inspection workers, thereby improving the efficiency of takeoff and landing, and establishing a safe environment for aircraft takeoff and landing. [0003] The target detection and information collection of foreign objects on the...
