## Abstract

A facial recognition system, comprising: an automatically adjustable camera rig comprising a plurality of movable cameras, wherein the plurality of movable cameras are moved by a camera control platform according to take enrollment images; a first input for receiving images from the automatically adjustable camera rig; a second input for receiving a plurality of images from an comparative input; a first computing memory for storing a machine learning model that includes a three dimensional and a two dimensional comparison between the received first input and the received second input, wherein the comparison uses key facial points to compute a distance between the first input and the second input; and a match output in a case of a distance within a predetermined threshold.

## Claims

### Claim 1

An identification and tracking system, comprising:
a visual sensor;
an infrared sensor synchronized with the visual sensor;
a temporary identification assigner associated with the visual sensor and capable of assigning a temporary identification to faces perceived by the visual sensor;
a facial feature assessment that applies a 3D mesh to the perceived faces to allow for the temporary identification, wherein the facial feature assessment assigns target zones of the perceived face that are suitably indicative of a body temperature of a person corresponded to the temporary identification;
a body temperature assessment that uses the infrared sensor to assess the body temperature of the person corresponded to the temporary identification at the target zones; and
an identification database that:
corresponds the temporary identification with the assessed body temperature;
non-thermally compares selected points of the 3D mesh of the temporary identification against a plurality of known identities;
extracts confusion factors from the comparison based solely on a location of the selected points in the 3D mesh; and
produces an identity match between the temporary identification and the plurality of known identities.

### Claim 2 (depends on 1)

The system of claim 1, wherein the confusion factors comprise at least one obstructed facial feature.

### Claim 3 (depends on 2)

The system of claim 2, wherein the obstruction comprises a mask.
