Abstract

The invention provides a tower-type airport runway foreign body positioning method, which carries out foreign body positioning by utilizing a tower-type airport runway foreign body detecting system. The tower-type airport runway foreign body detecting system comprises an optical detection module and a server end. The method comprises the following steps: the optical detection module is used for shooting a foreign body to obtain a foreign body image; the server end obtains physic coordinates of the foreign body in a target surface of a camera according to the foreign body image; the server end obtains spherical polar coordinates of the foreign body with respect to a rotary table according to the physic coordinates of the foreign body in the target surface and parameters of the rotary table; the server end converts the spherical polar coordinates of the foreign body with respect to the rotary table into Cartesian coordinates of the foreign body with respect to the rotary table; the server end converts the Cartesian coordinates of the foreign body with respect to the rotary table into geocentric coordinates of the foreign body; and the server end converts the geocentric coordinates of the foreign body into longitude and latitude coordinates of the foreign body. According to the tower-type airport runway foreign body positioning method, the longitude and latitude coordinates of the foreign body are generated according to the position of the rotary table, and thus accuracy of airport runway foreign body positioning is improved.

Description

technical field [0001] The invention relates to the technical field of optical positioning, in particular to a method for locating foreign objects on a tower-type airport runway. Background technique [0002] Foreign objects on airport runways are an important factor affecting flight safety and causing flight delays at airports. In recent years, in response to this problem, the civil aviation industry has proposed an automated airport runway foreign object detection system that can automatically detect runway status, detect and locate runway foreign objects in time, in order to replace manual inspections and improve work efficiency and reliability. [0003] The tower-type airport runway foreign object detection system is one of the above-mentioned automated airport runway foreign object detection systems. The system adopts a distributed layout and is composed of several optical detection sensors, servers and clients. Among them, the optical detection sensor is deployed on ...
