Embodiment Construction

[0035] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] The specific application object of the present invention is an airport runway foreign object detection system. The present invention proposes a rapid positioning method for detection of foreign objects on an airport runway and its software codes are implemented using VC++ programming. Aiming at the characteristics of a single background and uniform texture in the airport runway area, by recording the number of alarms for a certain object in the same field of view, Reduce the number of false alarms; at the same time, the image of the simulated airport runway is displayed under the video image, and the position information of the foreign object is displayed on the image of the simulated airport runway synchronously, so as to realize the rapid positioning of the actual position of the foreign object.

Abstract

The invention belongs to the technical field of optoelectronic product application, and particularly relates to an airfield runway foreign body detecting and rapid positioning method. By the adoption of a multi-frame accumulation algorithm, foreign body alarming position information and the number of alarming times are counted; targets of which the number of alarming times is greater than a threshold T are calculated by the adoption of the method of combining a simulation runway with actual position information, and actual positions of the targets are obtained according to the current view field serial number, actually measured view field size and target position information; finally, alarming frames of the targets and actual position information are displayed on an stimulation airfield runway image, and therefore rapid positioning for airfield runway foreign body detecting is achieved. By application of the technical scheme, operation of an airfield runway foreign body detecting system is more humanized, and foreign body position information is more accurate. Meanwhile, the actual positions of foreign bodies are displayed in a visual mode, the foreign bodies are positioned more rapidly, and convenience is brought to later clear-up work of the foreign bodies.

Description

technical field [0001] The invention belongs to the technical field of application of photoelectric products, and in particular relates to a rapid positioning method for foreign object detection on an airport runway. Background technique [0002] The present invention is based on an airport runway foreign object detection system, and its main function is to obtain detection data in the airport runway area through a detector, analyze the detection data, and obtain the existence status of foreign objects in the runway area. The invention quickly locates the foreign objects detected in the process of foreign object detection on the airport runway, sends an alarm prompt to the staff in time, and reminds the staff to remove the foreign objects as soon as possible, so as to ensure the operation safety of the airport. [0003] In practical applications, the video image of the airport runway area acquired by the detector presents the characteristics of a single background and unifor...
