Abstract

A method and system for calibrating cameras of a monitoring system, the method comprises receiving a plurality of video frames including a wide area view of a patient area from a primary camera of a monitoring subsystem and a view of a region of interest within the patient area from a secondary camera of the monitoring subsystem, detecting a patient event based on an analysis of given ones of the plurality of video frames corresponding to the wide area view, transmitting the given ones of the plurality of video frames and an identification of the patient event to a viewer client device, generating detection-based calibration instructions based on the patient event, wherein the detection-based calibration instructions including control information that controls operation of the secondary camera based on a location of the patient event, and transmitting the detection-based calibration instructions to the monitoring subsystem, wherein the monitoring subsystem configures the secondary camera based on the control information of the detection-based calibration instructions.

First claim

What is claimed is:

1. A method, in a data processing system comprising a processor and a memory, for calibrating cameras of a monitoring system, the method comprising:
receiving a plurality of video frames including a wide area view of a patient area from a primary camera of a monitoring subsystem and a view of a region of interest within the patient area from a secondary camera of the monitoring subsystem, the secondary camera comprising visible light and thermal imaging functionality;
detecting a patient event based on an analysis of given ones of the plurality of video frames corresponding to the wide area view;
transmitting the given ones of the plurality of video frames and an identification of the patient event to a viewer client device;
generating detection-based calibration instructions based on the patient event, the detection-based calibration instructions including control information that controls the functionality and operation of the secondary camera based on a location of the patient event; and
transmitting the detection-based calibration instructions to the monitoring subsystem, wherein the monitoring subsystem configures the functionality and operation of the secondary camera based on the control information of the detection-based calibration instructions.

2. The method of claim 1 wherein the control information includes at least one of move, pan, tilt, zoom, focus, lighting, and exposure control.

3. The method of claim 1 wherein the control information includes control of the secondary camera to focus or zoom in on an area of interest based on the location of the patient event.

4. The method of claim 1 further comprising:
receiving manual calibration instructions from a user of a viewer client device, the manual calibration instructions including control information that manually controls operation of the primary camera or the secondary camera by the user; and
transmitting the manual calibration instructions to the monitoring subsystem, wherein the monitoring subsystem configures the primary camera or the secondary camera based on the control information of the manual calibration instructions.

5. The method of claim 1 wherein the patient event includes at least one of a patient at risk of falling, the patient falling, the patient in need of intervention, the patient outside of a designated area, and patient motion.

6. The method of claim 1 wherein detecting the patient event further comprises detecting the patient event based on a primary field of view of the patient area.

7. The method of claim 1 wherein detecting the patient event further comprises detecting the patient event based on a secondary field of view of the patient area.

8. The method of claim 1 wherein the region of interest includes at least one of a wound, an intravenous insertion, or a face.

9. A system for calibrating cameras of a monitoring system, the system comprising:
a processor; and
a memory having executable instructions stored thereon that when executed by the processor cause the processor to:
receive a plurality of video frames including a wide area view of a patient area from a primary camera of a monitoring subsystem and a view of a region of interest within the patient area from a secondary camera of the monitoring subsystem, the secondary camera comprising visible light and thermal imaging functionality;
detect a patient event based on an analysis of given ones of the plurality of video frames corresponding to the wide area view;
transmit the given ones of the plurality of video frames and an identification of the patient event to a viewer client device;
generate detection-based calibration instructions based on the patient event, the detection-based calibration instructions including control information that controls the functionality and operation of the secondary camera based on a location of the patient event; and
transmit the detection-based calibration instructions to the monitoring subsystem, wherein the monitoring subsystem configures the functionality and operation of the secondary camera based on the control information of the detection-based calibration instructions.

10. The system of claim 9 wherein the control information includes at least one of move, pan, tilt, zoom, focus, lighting, and exposure control.

11. The system of claim 9 wherein the control information includes control of the secondary camera to focus or zoom in on an area of interest based on the location of the patient event.

12. The system of claim 9 further comprising the processor configured to:
receive manual calibration instructions from a user of a viewer client device, the manual calibration instructions including control information that manually controls operation of the primary camera or the secondary camera by the user; and
transmit the manual calibration instructions to the monitoring subsystem, wherein the monitoring subsystem configures the primary camera or the secondary camera based on the control information of the manual calibration instructions.

13. The system of claim 9 wherein the patient event includes at least one of a patient at risk of falling, the patient falling, the patient in need of intervention, the patient outside of a designated area, and patient motion.

14. The system of claim 9 further comprising the processor configured to detect the patient event based on a primary field of view of the patient area.

15. The system of claim 9 further comprising the processor configured to detect the patient event based on a secondary field of view of the patient area.

16. The system of claim 9 wherein the region of interest includes at least one of a wound, an intravenous insertion, or a face.

17. Non-transitory computer-readable media comprising program code that when executed by a programmable processor causes execution of a method for calibrating cameras of a monitoring system, the computer-readable media comprising:
computer program code for receiving a plurality of video frames including a wide area view of a patient area from a primary camera of a monitoring subsystem and a view of a region of interest within the patient area from a secondary camera of the monitoring subsystem, the secondary camera comprising visible light and thermal imaging functionality;
computer program code for detecting a patient event based on an analysis of given ones of the plurality of video frames corresponding to the wide area view;
computer program code for transmitting the given ones of the plurality of video frames and an identification of the patient event to a viewer client device;
computer program code for generating detection-based calibration instructions based on the patient event, the detection-based calibration instructions including control information that controls the functionality and operation of the secondary camera based on a location of the patient event; and
computer program code for transmitting the detection-based calibration instructions to the monitoring subsystem, wherein the monitoring subsystem configures the functionality and operation of the secondary camera based on the control information of the detection-based calibration instructions.

18. The non-transitory computer-readable media of claim 17 wherein the control information includes at least one of move, pan, tilt, zoom, focus, lighting, and exposure control.

19. The non-transitory computer-readable media of claim 17 wherein the control information includes control of the secondary camera to focus or zoom in on an area of interest based on the
