Embodiment Construction

[0036] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0037] refer to figure 1 As shown, a kind of aircraft berth guidance method based on laser point cloud of the present invention, comprises steps as follows:

[0038] Step S1, the multi-threaded laser radar obtains the original data of the parking stand scene, adjusts the pitch angle of the laser radar according to the height of the laser radar erection, and ensures that the target aircraft is in a laser scanning intensive area to obtain clear laser data;

[0039] Step S2, analyze and convert the original data obtained by the laser radar into point cloud format data, use libpcap combined with a specific calibration file to analyze the UDP data packets of the multi-threaded laser radar, and ob...

Abstract

The invention discloses an aircraft berth guiding method based on a laser point cloud. The aircraft berth guiding method comprises the following steps that: a multi-thread laser radar acquires original data of a berth scene; the laser radar data are converted into point cloud format data; related point cloud preprocessing is carried out on the point cloud data to obtain detection area data; a target aircraft is captured in a detection area by using a point cloud target detection algorithm; a target motion state of the target aircraft is tracked by using a point cloud target tracking algorithm;a point cloud feature extraction algorithm is used for the target aircraft to obtain aircraft key features; and the extracted aircraft key feature parameters match feature data in a database to identify the type of the target aircraft. On the basis of the designed algorithm, the method can adapt to an actual airport berth application scene; and the aircraft berth guiding function can be rapidly,accurately and stably realized.

Description

technical field [0001] The invention belongs to the technical field of laser radar object detection, identification and measurement, and specifically refers to an aircraft berth guidance method based on a laser point cloud for the detection and tracking of a target aircraft in a berth. Background technique [0002] The aircraft parking guidance system is a set of human-machine dialogue command system that can automatically guide the taxiing aircraft to quickly reach the parking position on the apron and park accurately. The display device in front of the parking space displays information such as aircraft position, attitude and speed, which can effectively guide aircraft of different types to different stop lines and accurately dock with the boarding bridge. At the same time, it is connected to the airport data integration platform, which can provide real-time azimuth guidance, model parameters, flight information, taxiing speed, aircraft position signals and other contents ...
