Human detection system for construction machine
First Claim
1. A human detection system for a construction machine that is configured to detect the presence of a human around the construction machine by using an image captured by an imaging device attached to the construction machine, the system comprising:
- a memory; and
a processor coupled to the memory, and configured tosearch digital data of the captured image for digital data of a feature image representing a human characteristic portion to identify the feature image in the captured image;
extract a part of the digital data of the captured image as a target image, the target image including an image corresponding in size to a whole human body that includes the identified feature image; and
identify whether the image included in the target image is a human image,wherein the target image corresponds to a preset point most correlated with a position of the feature image in the captured image among a plurality of preset points that are assumed standing positions of the human in a real space.

Abstract
A human detection system may detect the presence of a human around a shovel by using an image captured by an imaging device attached to the shovel. Also, the human detection system may have an extracting part that extracts a part of the captured image as an identification process target image, and an identifying part that identifies whether an image included in the identification process target image is an image of a human. A region of the identification process target image is preliminarily associated with one of head image positions in the captured image. The extracting part finds out a helmet image in the captured image, and extracts the identification process target image by associating a representative position of the helmet image with one of the head image positions.

16. A human detection system that is configured to detect the presence of a human by using an image captured by an imaging device of which an optical axis is directed diagonally downward, the system comprising:
-
a memory; and a processor coupled to the memory, and configured to search digital data of the captured image for digital data of a feature image representing a human characteristic portion to identify the feature image in the captured image; extract a part of the digital data of the captured image as a target image, the target image including an image corresponding in size to a whole human body that includes the identified feature image; and identify whether the image included in the target image is a human image, wherein the target image corresponds to a preset point most correlated with a position of the feature image in the captured image among a plurality of preset points that are assumed standing positions of the human in a real space. - View Dependent Claims (17, 18)
