Abstract
The system is configured to locate, track and/or analyze activities of living beings in an environment. The system does not require the input of personal biometric data. The sensor system detects infrared (IR) energy from a living being moving in an environment, determines a temperature of the living being based on IR energy data of the IR energy, projects the temperature onto a grid having sequential pixels, determines serial changes of the temperature in the sequential pixels and determines a trajectory of the living being based on the serial changes of the temperature in the sequential pixels.
Claims34
The method comprising:
- determining, by a sensor system, a plurality of temperatures based on infrared (IR) energy data of IR energy from an environment, wherein the sensor system includes a sensor node of a plurality of sensor nodes;
- projecting, by the sensor system, the plurality of temperatures onto a grid comprising pixels;
- determining, by the sensor system, differences in the plurality of temperatures across the pixels;
- and
- determining, by the sensor system, at least one of a presence or position of a plurality of living beings, based on at least one of the differences or variations in the plurality of temperatures across the pixels.
An article of manufacture including a non-transitory, tangible computer readable storage medium having instructions stored thereon that, in response to execution by a sensor system, cause the sensor system to perform operations comprising:
- determining, by the sensor system, a plurality of temperatures based on infrared (IR) energy data of IR energy from an environment, wherein the sensor system includes a sensor node of a plurality of sensor nodes;
- projecting, by the sensor system, the plurality of temperatures onto a grid comprising pixels;
- determining, by the sensor system, differences in the plurality of temperatures across the pixels;
- and
- determining, by the sensor system, at least one of a presence or position of a plurality of living beings, based on at least one of the differences or variations in the plurality of temperatures across the pixels.
A sensor system comprising:
- a processor;
- and
- a tangible, non-transitory memory configured to communicate with the processor,
- the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising:
- determining, by the processor, a plurality of temperatures based on infrared (IR) energy data of IR energy from an environment, wherein the sensor system includes a sensor node of a plurality of sensor nodes;
- projecting, by the processor, the plurality of temperatures onto a grid comprising pixels;
- determining, by the processor, differences in the plurality of temperatures across the pixels;
- and
- determining, by the processor, at least one of a presence or position of a plurality of living beings, based on at least one of the differences or variations in the plurality of temperatures across the pixels.
