Multi-view human detection using semi-exhaustive search

摘要

A human monitoring system includes a plurality of cameras and a visual processor. The plurality of cameras are disposed about a workspace area, where each camera is configured to capture a video feed that includes a plurality of image frames, and the plurality of image frames are time-synchronized between the respective cameras. The visual processor is configured to receive the plurality of image frames from the plurality of vision-based imaging devices and detect the presence of a human from at least one of the plurality of image frames using pattern matching performed on an input image. The input image to the pattern matching is a sliding window portion of the image frame that is aligned with a rectified coordinate system such that a vertical axis in the workspace area is aligned with a vertical axis of the input image.

1. A human monitoring system for monitoring a workspace area having automated moveable equipment, the system comprising:
a plurality of cameras disposed about the workspace area, each camera configured to capture a video feed that includes a plurality of image frames; a visual processor configured to:
receive the plurality of image frames from the plurality of cameras;detect the presence of a human from at least one of the plurality of image frames using pattern matching performed on an input image;
wherein the input image to the pattern matching is a sliding window portion of the at least one image frame;wherein the sliding window portion is aligned with a rectified coordinate system such that a vertical axis in the workspace area is aligned with a vertical axis of the input image; andprovide an alert if the detected human is proximate the automated moveable equipment.
