Title
(EN) MAPPING METHOD OF LAWN MOWER ROBOT
(FR) PROCÉDÉ DE CARTOGRAPHIE D'UN ROBOT-TONDEUSE À GAZON
Abstract
(EN)
Disclosed herein is a mapping method of a lawn mower robot including a first image mapping operation of generating a first travel image of a three-dimensional region based on an aerial image of a work target region, a first map displaying operation of dividing the first travel image into a mowing region and an obstacle region, converting the first travel image into a first travel map, and displaying the first travel map, a first anchor displaying operation of recommending the number and installation locations of anchors on the first travel map when the mowing region and the obstacle region are divided, an anchor location determination operation of determining whether the anchors are installed at the installation locations, and a path generation operation of generating a travel path of the lawn mower robot on the first travel map. The mapping method may improve work efficiency of the lawn mower robot.

L'invention concerne un procédé de cartographie d'un robot-tondeuse à gazon, comprenant : une opération de cartographie de première image consistant à générer une première image de déplacement d'une région tridimensionnelle sur la base d'une image aérienne d'une région cible de travail; une opération d'affichage de première carte consistant à diviser la première image de déplacement en une région de tonte et une région d'obstacle, à convertir la première image de déplacement en une première carte de déplacement, et à afficher la première carte de déplacement; une opération d'affichage de premier ancrage consistant à recommander le nombre et les emplacements d'installation d'ancrages sur la première carte de déplacement une fois la région de tonte et la région d'obstacle divisées; une opération de détermination d'emplacements d'ancrages consistant à déterminer si les ancrages sont installés au niveau des emplacements d'installation; et une opération de génération de trajet consistant à générer un trajet de déplacement du robot-tondeuse à gazon sur la première carte de déplacement. Le procédé de cartographie peut améliorer l'efficacité de travail du robot-tondeuse à gazon.
