(DE) PERSONENDETEKTIONSSYSTEM FÜR EINE BAUMASCHINE
(EN) HUMAN DETECTION SYSTEM FOR CONSTRUCTION MACHINE
(FR) SYSTÈME DE DÉTECTION DE PERSONNE POUR ENGIN DE CHANTIER
Abstract
(EN) A human detection system (100) detects the presence of a human around a shovel by using an image captured by an imaging device (40) that is attached to the shovel and that captures a human from diagonally above. The human detection system (100) has an extracting part (31) that extracts a part of the captured image as an identification process target image, and an identifying part (32) that identifies whether an image included in the identification process target image extracted by the extracting part (31) is an image of a human by an image processing. An identification process target image region (TRg) in the captured image corresponds to a virtual plane region (TR) having a predetermined size in a real space. In the real space, the virtual plane region (TR) faces toward the imaging device (40) and is inclined with respect to a horizontal surface.
(FR) L'invention concerne un système (100) de détection de personne, lequel permet de détecter la présence d'une personne dans le périmètre d'un outil de terrassement au moyen d'une image capturée d'un dispositif (40) de capture d'image fixé sur l'engin de terrassement de manière à filmer une personne obliquement depuis le haut. Ce système (100) de détection de personne possède: une unité d'extraction (31) pour extraire en tant qu'image à identifier une partie d'une image capturée; et une unité d'identification (32) pour identifier au moyen d'un traitement d'image une image de personne contenue dans l'image à identifier extraite par l'unité d'extraction (31). Une zone (TRg) de l'image à identifier dans l'image capturée correspond à une zone (TR) de plan virtuel d'une taille déterminée dans l'espace réel. Cette zone (TR) de plan virtuel, dans l'espace réel, est dirigée vers le dispositif (40) de capture d'image et est inclinée par rapport au plan horizontal.
