HUMAN DETECTION SYSTEM FOR CONSTRUCTION MACHINE

A human detection system (100) detects the presence of a human around a shovel by using an image captured by an imaging device (40) attached to the shovel. Also, 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 is an image of a human. A region (TRg) of the identification process target image is preliminarily associated with one of head image positions (AP) in the captured image. The extracting part (31) finds out a helmet image (HRg) in the captured image, and extracts the identification process target image by associating a representative position (RP) of the helmet image (HRg) with one of the head image positions (AP).
