Title
(EN) Human detection system for construction machine
(ZH) 施工机械用人检测系统以及挖土机
Abstract
(EN) A human detection system (100) detects a person present in the periphery of a shovel using the captured image of an image-capturing device (40) that is attached to the shovel so as to capture the image of the person from diagonally above. The human detection system (100) has an extraction unit (31) for extracting part of the captured image as an image to be processed for identification, and an identification unit (32) for identifying whether the image included in the image to be processed for identification extracted by the extraction unit (31) is the image of a person. An area (TRg) of the image to be processed for identification in the captured image corresponds to a virtual plane area (TR) of a prescribed size in the real space. The virtual plane area (TR), in the real space, faces toward the image-capturing device (40) and is inclined with respect to the horizontal plane.
(ZH) 人体检测系统(100)使用以从斜上方拍摄人体的方式安装于挖土机的摄像装置(40)的摄像图像来检测存在于挖土机的周边的人体。人体检测系统(100)具有:抽取部(31),抽取摄像图像的一部分作为识别处理对象图像;及识别部(32),通过图像处理来识别抽取部(31)所抽取的识别处理对象图像中所包含的图像是否为人体图像。摄像图像中的识别处理对象图像区域(TRg)对应于实际空间中的规定尺寸的虚拟平面区域(TR)。虚拟平面区域(TR)在实际空间中朝向摄像装置(40)的方向且相对于水平面倾斜。
