Vehicle elevated body temperature identification

A non-contact body temperature detection system of a vehicle, the system comprising:

• a thermography camera configured to generate an image of a user within a passenger cabin of the vehicle;
• a head detection module configured to determine a first area of the image including a head of the user;
• an eye detection module configured to determine a second area within the first area of the image including an eye of the user;
• a tear duct detection module configured to determine a third area within the second area of the image including a tear duct of the user;
• a temperature module configured to determine a body temperature of the user based on (a) a sum of temperatures of the pixels, respectively, of the third area of the image divided by (b) a total number of the pixels of the third area;
• and
• an indicator module configured to indicate whether the user has an elevated body temperature when the body temperature of the user is greater than a temperature threshold.

A non-contact body temperature detection method for a vehicle, the method comprising:

• by a thermography camera, generating an image of a user within a passenger cabin of the vehicle;
• determining a first area of the image including a head of the user;
• determining a second area within the first area of the image including an eye of the user;
• determining a third area within the second area of the image including a tear duct of the user;
• determining a body temperature of the user based on pixels within the third area of the image including:
• determining a respective temperature for each pixel in the first area, the second area, and the third area;
• and
• determining the body temperature based on the temperatures of the pixels, respectively;
• indicating whether the user has an elevated body temperature when the body temperature of the user is greater than a temperature threshold;
• setting the temperature threshold to a first predetermined temperature in response to a determination that the user is an adult;
• and
• setting the temperature threshold to a second predetermined temperature in response to a determination that the user is not an adult.
