Abstract

Systems and techniques are provided in which one or more environmental sensors collect data about an environment. An environmental hazard assessment module collects and analyzes data obtained by the environmental sensors to automatically identify, categorize, and/or rate the severity of potential environmental hazards. The hazards are provided to a user for a particular region of the environment or for a larger environment that includes multiple regions.

Claims (32)

1. A system comprising:

one or more environmental sensors including at least a camera, each environmental sensor of the one or more environmental sensors configured to obtain environmental data describing at least one physical attribute of an environment in which the system is disposed, the environmental data including at least image data obtained by the camera;

a processing system configured to receive the environmental data from the one or more environmental sensors and, based upon the environmental data, identify at least one potential fall hazard in the environment and a degree of risk associated with the at least one potential fall hazard; and

a reporting component configured to provide an indication of the identified at least one potential fall hazard and the degree of risk associated with the fall hazard.

2. The system of claim 1 , wherein the system comprises a portable computing device, the portable computing device comprising the one or more environmental sensors, the processing system, and the reporting component.

3. The system of claim 2 , wherein the reporting component comprises a display screen.

4. The system of claim 2 , wherein the portable computing device is selected from a group consisting of: a tablet, a smart phone, and a portable general-purpose computer.

5. The system of claim 1 , wherein the camera comprises an RGB camera configured to capture the image data of the environment.

6. The system of claim 5 , wherein the processing system is configured to identify a floor transition, an item of clutter, or both based upon the image data.

7. The system of claim 1 , wherein the one or more environmental sensors comprises a topology sensor configured to collect topological data about the environment, and wherein the processing system is configured to identify a floor transition as the identified at least one potential fall hazard based upon the topological data.

8. The system of claim 1 , wherein the one or more environmental sensors comprises an ambient light sensor, and wherein the processing system is configured to identify a low light condition as the identified at least one potential fall hazard based upon ambient light data collected by the ambient light sensor.

9. The system of claim 1 , wherein the processing system is configured to implement a neural network to identify the at least one potential fall hazard based upon the environmental data, wherein the neural network is trained based upon historic environmental data.

10. The system of claim 1 , comprising:

a portable computing device, wherein the portable computing device comprises the one or more environmental sensors; and

a network communication interface, configured to provide the environmental data to the processing system.

11. A method comprising:

receiving, from each of one or more environmental sensors, environmental data describing an environment in which the one or more environmental sensors is disposed;

extracting, from the environmental data, one or more physical attributes of the environment;

based upon the one or more physical attributes, automatically identifying at least one potential hazard in the environment;

based upon the one or more physical attributes, automatically determining a degree of risk associated with the at least one potential hazard;

determining a risk score for a portion of the environment in which the physical attributes are located based upon properties of the environment;

determining a total risk score for the environment based upon the degree of risk associated with the at least one potential hazard and the risk score for the portion of the environment; and

automatically generating a report indicating a presence of the at least one potential hazard, the degree of risk associated with the at least one potential hazard, and the total risk score for the area.

12. The method of claim 11 , wherein the one or more environmental sensors are disposed within a portable computing device.

13. The method of claim 12 , further comprising automatically displaying the report on a display screen of the portable computing device.

14. The method of claim 12 , wherein the portable computing device is selected from a group consisting of: a tablet, a smart phone, and a portable general-purpose computer.

15. The method of claim 11 , wherein the one or more environmental sensors comprises an RGB camera configured to capture image data of the environment, and wherein at least one of the one or more physical attributes is determined based upon the image data.

16. The method of claim 15 , wherein the step of identifying the at least one potential hazard comprises identifying a floor transition, an item of clutter, or both based upon the image data.

17. The method of claim 11 , wherein the one or more of environmental sensors comprises a topology sensor configured to collect topological data about the environment, and wherein the step of identifying the at least one potential hazard comprises identifying a floor transition as the at least one potential hazard based upon the topological data.

18. The method of claim 11 , wherein the one or more of environmental sensors comprises an ambient light sensor, and wherein the step of identifying the at least one potential hazard comprises identifying a low light condition as the at least one potential hazard based upon ambient light data collected by the ambient light sensor.

19. The method of claim 11 , wherein the step of automatically identifying the at least one potential hazard, the step of automatically determining the degree of risk, or both, is performed by an artificial neural network.

20. The method of claim 11 , further comprising providing the environmental data to a remote computing platform, wherein the remote computing platform generates the report.
