[0066] Step 1: Obtain the detection information of the detection target.
[0067] The millimeter-wave radar detects the detection target and outputs detection information, including the longitude LO_t=114.68892400°, latitude LA_t=38.29097034°, height HE_t=70.6m, and signal-to-noise ratio SNR_t=15dB of the detection target;
[0068] Step 2: Output a first judgment result according to the position coordinates of the centerline light and the position coordinates of the detection target.
[0069] Compare the longitude and latitude height information of the detection target with the longitude and latitude height information of the centerline light to determine whether the position difference between the detection target and a certain centerline light is less than the position difference threshold of 2 meters. Here, if the centerline light near the detection target is selected, the position of the centerline light The coordinates are: LO_l1=114.6889304953°, LA_l1=38.2909552067°, HE_...

Abstract
The invention provides a method for deducting a center line lamp of an FOD detection device and the FOD detection device, relates to the technical field of aviation safety, and mainly solves the technical problem of how to distinguish the center line lamp from the foreign matters on an airfield runway. The method comprises the following steps of acquiring the measurement information of the centerline lamp and the detection information of a detection target; outputting a first judgment result according to the position coordinates of the center line lamp and the position coordinates of the detection target; and if the first judgment result shows that the detection target is not the FOD, performing secondary judgment according to the signal-to-noise ratio of the detection target, and if the second judgment result shows that the detection target is not the FOD, determining the detection target as the center line lamp, and excluding the detection target. Therefore, in the field patrol detection process of the mobile FOD detection device, the problem that the center line lamp is identified as an FOD target mistakenly is solved. Moreover, the speed of the FOD inspection process is increased, the efficiency of the inspection personnel is improved, and the quality of the FOD inspection is guaranteed.
Description
technical field [0001] The invention relates to the technical field of aviation safety, in particular to a method for subtracting a center line lamp of FOD detection equipment and the FOD detection equipment. Background technique [0002] FOD (Foreign Object Debris) on the airport runway refers to any object that appears in an inappropriate position in the airport. This object can scratch the aircraft tires, hit the aircraft fuel tank or the aircraft body, cause the aircraft to slide off the runway, and cause aircraft accidents. Threatening the life and property of passengers, causing flight delays, interrupting takeoffs, and causing huge economic losses. [0003] At present, the detection of FOD at home and abroad basically relies on manual regular inspections. This method is not only inefficient and unreliable, but also takes up the use of the runway, so that the number of flights is forced to be reduced. Moreover, due to human visual fatigue, the missed detection rate is ...
