Non-Contact Breathing Activity Monitoring And Analyzing System Through Thermal On Projection Medium Imaging

A system comprising:

• a thin-medium;
• a thermal camera configured to image projections of an exhale cross-section on the thin-medium;
• a communication interface coupled to the thermal camera to receive a sequence of thermal images depicting a thermal distribution of the exhale on the thin-medium;
• a processor, and
• a memory having stored thereon a set of instructions stored thereon that when executed by the processor, cause the processor to generate a representation or model of the exhale.

A method of analysis for monitoring and extracting metrics related to pulmonary function, the method comprising:

• imaging a thin-medium while a user exhales onto a surface of the thin-medium;
• creating a temporary representation of a thermal signature on the thin-medium that represents exhale behaviors,
• wherein the temporary representation includes an intensity value range for each pixel;
• formulating, for each intensity value within the image, iso-lines to form an iso-line map of gradients and exhale boundary captured over time to form a three-dimensional representation of the exhale;
• deriving, using image processing to the iso-line map of gradients, respiratory information;
• and
• deriving, using machine learning, a correlation between the intensity values and exhale behaviors over time with objective metrics.
