  • Patent number: 10562644
    Abstract: 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 head of an aircraft is expected to appear, echo data based on 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 head of the aircraft, echo data based on 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 by adjusting the vertical scanning angle of the laser scanning, and the position of the nose is displayed in real time.

  • Patent number: 10290219
    Abstract: A machine vision-based method and system for aircraft docking guidance and aircraft type identification, comprising: S1: a monitoring scenario is divided into different information processing function areas; S2: a captured image is pre-processed; S3: 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: 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: 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: 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.

  • Patent number: 10255520
    Abstract: 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 fusion module. The method includes: in step 1000, obtaining, by the machine vision sub-system, an image via image capturing means, and calculating a first aircraft front wheel position therefrom; in step 2000, obtaining, by the laser scanning sub-system, the position of the nose of an aircraft via laser scanning means, and calculating a second aircraft front wheel position; in step 3000, fusing the first aircraft front wheel position and the second aircraft front wheel position according to a fusion rule, to obtain deviation of an aircraft front wheel.
