Systems for collecting thermal measurements of the face

摘要

This disclosure describes various systems for collecting thermal measurements of regions of a user's face. Each of the systems includes a frame configured to be worn on the user's head, and one or more lightweight thermal cameras that are coupled to the frame and configured to take thermal measurements of a region of interest on the user's face. Due to their coupling to the frame, the thermal cameras remain pointed at their respective regions of interest event when the user's head performs angular movements. The thermal measurements collected by some embodiments of the systems described herein may be utilized for a variety of applications that involve detecting different types of physiological responses or medical disorders.

主权项

1. A system configured to take thermal measurements indicative of a physiological response, comprising:
a frame configured to be worn on a user's head; first, second, third, and fourth thermal cameras, each of which: weighs below 5 g, is physically coupled to the frame, and is located less than 15 cm away from the user's face; the first and third thermal cameras are located to the right of the vertical symmetry axis that divides the face; the second and fourth thermal cameras are located to the left of the vertical symmetry axis; and the third and fourth thermal cameras are located at least 1 cm below the first and second thermal cameras, respectively; the first thermal camera is configured to take thermal measurements of a first region of interest (THROI1), wherein ROI1 covers a portion of the right side of the user's forehead; the second thermal camera is configured to take thermal measurements of a second ROI (THROI2), wherein ROI2 covers a portion of the left side of the forehead; the third thermal camera is configured to take thermal measurements of a third ROI (THROI3), wherein ROI3 covers a portion of the right side of the user's upper lip; and the fourth thermal camera is configured to take thermal measurements of a fourth ROI (THROI4), wherein ROI4 covers a portion of the left side of the user's upper lip.
