Abstract
A monitoring system can be configured to monitor activities or actions occurring in clinical settings, such as hospitals. The monitoring system can improve patient safety. The system can use visual and/or other tracking methods. The system can detect and/or identify people in a clinical setting. The system can also track activities of the people, for example, to improve adherence to hygiene protocols.
Claims21
A system for tracking, on a local network, movements of people in an enclosed room with an entrance/exit, the system comprising:
- a camera configured to capture image data from a viewpoint in the room;
- and
- a hardware processor in physical proximity to the camera, the hardware processor configured to:
- detect each person in an image frame from the image data;
- extract coordinates of each detected person relative to the image frame;
- and
- update tracks monitored by the hardware processor based on the coordinates of each detected person without storing any image from the image data, wherein a new track is assigned to a person detected within a predetermined distance from the entrance/exit and not having been assigned a track in a previous image frame from the image data, wherein only non-image data is transmitted by the hardware processor.
A system for tracking movements of a person in a clinical room, wherein more than one person is present at the clinical room, the system comprising:
- a first camera configured to capture first image data from a first viewpoint in the clinical room;
- a first hardware processor in physical proximity to the first camera, the first processor configured to detect each person in an image frame from the first image data and assign a unique boundary box to each person, the first processor further configured to track movement of the boundary boxes in subsequent image frames from the first image data without storing any image from the first image data;
- a second camera configured to capture second image data from a second viewpoint in the clinical room;
- and
- a second hardware processor in physical proximity to the second camera, the second processor configured to detect each person in an image frame from the second image data and assign a unique boundary box to each person, the second processor further configured to track movement of the boundary boxes in subsequent image frames from the second image data without storing any image from the first image data,
- wherein at least one of the first or second cameras comprises a depth camera, the first and/or second processor configured to detect occlusion of a person in the clinical room by another person or object using depth information from the depth camera, wherein only non-image data is transmitted by the first or second hardware processor.
