System and method of multi-lane elevated body temperature preventative scanning solution using GigE vision and tracking

A computer-implemented method of multi-lane elevated body temperature (EBT) preventative scanning using GigE vision and tracking scanning system, the method comprising the steps of:

• receiving thermal image data from a far-field thermal camera with a zoom-in lens and from a near-field thermal camera;
• detecting faces and tracking persons with the far-field thermal camera and handing off tracking to the near-field thermal camera upon approach to a designated scanning area;
• for each person, generating a time-ordered queue of sub-frame facial images across the hand-off interval and aggregating temperature values derived from facial keypoints across the queue to determine an EBT pass/fail result;
• and
• providing a notification to a UI indicative of the per-person EBT result.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause a system to perform operations comprising:

• receiving thermal image data from a far-field thermal camera with a zoom-in lens and from a near-field thermal camera;
• detecting faces and tracking persons with the far-field thermal camera and handing off tracking to the near-field thermal camera;
• building a time-ordered queue of sub-frame facial images for each person across the hand-off interval;
• aggregating facial-keypoint temperatures across the queue to determine an EBT pass/fail result;
• and
• outputting the result to a user interface (UI).
