摘要:
A laser scanning-based aircraft docking guidance system and method, the method comprising: a capturing step: laser scanning in the horizontal direction is performed on a position where the front of an aircraft is expected to appear, echo data of the laser scanning is obtained, and the echo data is judged according to a judging condition, so as to determine whether the aircraft has appeared; a guiding step: after the aircraft has appeared, laser scanning in the horizontal direction is performed on the front of the aircraft, echo data of the laser scanning is obtained, and the position of the nose of the aircraft is determined; a tracking step: as the aircraft moves forward, the position of the nose is tracked via adjusting the vertical scanning angle of the laser scanning, and the position of the nose is displayed in real time. The system and method implement capturing, guiding and tracking of the aircraft, obtain the real-time position of the aircraft via accurate laser scanning, and perform displaying, so as to provide a pilot with a prompt for berthing. In addition, the system and method automatically identify and verify the aircraft type, improving aircraft docking security.

A machine vision-based method and system for aircraft docking guidance and aircraft type identification, the method comprising: S1, an aircraft berthing scenario setting step: a monitoring scenario is divided into different information processing function areas; S2, an image pre-processing step: a captured image is pre-processed; S3, an aircraft capturing step: the engine and the front wheel of an aircraft are identified in the image, so as to confirm that the aircraft has appeared in the image; S4, an aircraft tracking step: continuous tracking and real-time updating are performed on the image of the engine and the front wheel of the aircraft captured in step S3; S5, an aircraft positioning step: real-time positioning of the aircraft is implemented and the degree of deviation of the aircraft with respect to a guide line and the distance with respect to a stop line are accurately determined; S6, information displaying: the degree of deviation of the aircraft with respect to the guide line and the distance with respect to the stop line of step S5 are outputted and displayed.
摘要:
A system and method for aircraft docking guidance and aircraft type identification. The method is executed in the system for aircraft docking guidance and aircraft type identification comprising a machine vision sub-system, a laser scanning sub-system and a merging module. The method comprises: step 1000, the machine vision sub-system obtains an image via image capturing means, and calculates a first aircraft front wheel position therefrom; step 2000, the laser scanning sub-system obtains the position of the nose of an aircraft via laser scanning means, and extrapolates a second aircraft front wheel position; step 3000, the first aircraft front wheel position and the second aircraft front wheel position are merged according to a merging rule, and an aircraft front wheel deviation is obtained.
