Title (EN) IMAGE SENSOR BASED AUTONOMOUS LANDING
(FR) ATTERRISSAGE AUTONOME BASÉ SUR UN CAPTEUR D'IMAGES
Abstract:
(EN) A computer-implemented method of controlling an aircraft during autonomous landing. The method includes using a computer for performing the following: applying image processing on an image captured by a camera on board the aircraft while approaching a runway for identifying in the image a touchdown point (TDP) of the runway; calculating a deviation, in image parameters, of the TDP relative to the center of the image; converting the deviation in image parameters to angular and distance deviation values based on predefined ratios; calculating an offset of the aircraft's position relative to a landing corridor ending at the identified TDP based on the calculated angular and distance deviation; and transmitting the calculated offset to an aircraft control system configured to provide instructions for controlling the aircraft; wherein the offset is used for controlling the aircraft for guiding the aircraft towards the landing corridor to enable landing.
(FR) L'invention concerne un procédé mis en oeuvre par ordinateur pour commander un aéronef pendant un atterrissage autonome. Ce procédé consiste à utiliser un ordinateur pour mettre en oeuvre les étapes suivantes : application d'un traitement d'image à une image capturée par une caméra à bord de l'aéronef lors de l'approche d'une piste afin d'identifier dans l'image un point de toucher des roues (TDP) sur la piste; calcul d'une déviation, dans les paramètres d'image, du TDP par rapport au centre de l'image; conversion de la déviation dans les paramètres d'image en valeurs de déviation angulaire et de distance sur la base de facteurs prédéfinis; calcul d'un décalage de la position de l'aéronef par rapport à un couloir d'atterrissage se terminant au niveau du TDP identifié sur la base de la déviation angulaire et de distance calculée; et transmission du décalage calculé à un système de commande d'aéronef conçu pour fournir des instructions pour commander l'aéronef; le décalage étant utilisé pour commander l'aéronef de manière à guider l'aéronef en direction du couloir d'atterrissage pour permettre l'atterrissage.
