The present invention provides a method for locating foreign objects on a tower-type airport runway, which uses a tower-type airport runway foreign-object detection system to locate foreign objects, wherein the tower-type airport runway foreign-object detection system includes an optical detection module and a server end; the method includes steps: The optical detection module shoots the foreign object to obtain the image of the foreign object; the server obtains the physical coordinates of the foreign object on the target surface of the camera according to the image of the foreign object; Spherical coordinates; the server converts the spherical coordinates of the foreign object relative to the turntable into Cartesian coordinates of the foreign object relative to the turntable; the server converts the Cartesian coordinates of the foreign object relative to the turntable into the geocentric coordinates of the foreign object; The coordinates are converted to the latitude and longitude coordinates of the foreign object. The method for locating the foreign matter on the tower runway of an airport according to the invention generates the longitude and latitude coordinates of the foreign matter according to the position of the turntable, thereby improving the accuracy of locating the foreign matter on the airport runway.
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 ...
