Abstract
(EN) Provided is a drilling position determination system capable of appropriately determining a drilling start position according to the shape of an object to be drilled. The drilling position determination system comprises an imaging device (9) that images an object (100) to be drilled having a mound-like shape and a bucket (12) of a work machine, and a start position determination unit (8) capable of determining the drilling start position of the bucket with respect to the object to be drilled. The start position determination unit determines, as the drilling start position on the basis of detection data from the imaging device, a bucket position where the bucket is not entirely hidden behind the object to be drilled but the object to be drilled and the bucket partially overlap each other when the bucket is viewed from the body of the work machine.
(FR) L'invention concerne un système de détermination de position de forage capable de déterminer de manière appropriée une position de début de forage en fonction de la forme de l'objet à forer. Le système de détermination de position de forage comprend un dispositif d'imagerie (9) qui capture des images d'un objet (100) à forer ayant une forme de type monticule et un godet (12) d'un engin de chantier, et une unité de détermination de position de départ (8) pouvant déterminer la position de début de forage du godet par rapport à l'objet à forer. L'unité de détermination de position de départ détermine, en tant que position de départ de forage sur la base des données de détection provenant du dispositif d'imagerie, une position de godet dans laquelle le godet n'est pas entièrement caché derrière l'objet à forer mais l'objet à forer et le godet se chevauchent partiellement lorsque le godet est vu depuis le corps de l'engin de chantier.
(JA) 掘削対象物の形状に応じた掘削開始位置を適切に決定することができる掘削位置決定システムを提供する。掘削位置決定システムは、山形状の掘削対象物(100)および作業機械が有するバケット(12)を撮像する撮像装置(9)と、掘削対象物に対するバケットの掘削開始位置を決定することが可能な開始位置決定部(8)と、を備える。開始位置決定部は、撮像装置の検出データに基づいて、作業機械の機体からバケットを見たときに、バケットが掘削対象物に完全に隠れずに、掘削対象物とバケットとが一部重なるときのバケットの位置を前記掘削開始位置として決定する。
