Systems, apparatus, and methods for occupancy tracking using augmented reality

A non-transitory computer readable medium comprising machine-readable instructions that cause at least one processor circuit to at least:

• detect a first face and a second face in one or more frames of image data, the first face corresponding to a first subject in an interior of an air vehicle, the second face corresponding to a second subject in the interior of the air vehicle;
• define a first facial unit representing the first face in the one or more frames and a second facial unit representing the second face in the one or more frames;
• cause a first augmented reality marker to overlay the first facial unit in the one or more frames including the first facial unit and a second augmented reality marker to overlay the second facial unit in the one or more frames including the second facial unit;
• and
• determine an occupancy metric of the interior of the air vehicle based on the first augmented reality marker and the second augmented reality marker.

An apparatus comprising:

• memory;
• machine-readable instructions;
• and
• at least one processor circuit to execute the machine-readable instructions to:
• define facial units representing respective faces of subjects in an environment captured in one or more images based on facial features corresponding to the respective faces;
• cause a virtual object to be positioned over at least a portion of each facial unit in the one or more images;
• and
• determine an occupancy metric for the subjects in the environment based on the virtual objects.
