Classification: CPC G | IPC G

Claim 3:
4. The method of claim 3, further comprising:
at the first sensor block during a second time period:
capturing a second sequence of frames by the optical sensor;
for each frame in the second sequence of frames:
detecting the first human within the first region-of-interest in the frame;
detecting a human object type, in the set of object types, of the first human; and
detecting a first location of the first human, at a time of the frame, within the first region-of-interest in the frame;

storing human object types and locations of the first human, detected in the second sequence of frames, in a second set of containers; and
transmitting the second set of containers to the computer system; and

at the computer system:
initializing a second visualization layer representing the first region-of-interest;
calculating a second frequency of presence of the human object type, in the set of object types, intersecting the first pixel in the second visualization layer over the second time period based on the second set of containers;
calculating the color value for the first pixel based on the second frequency of presence;
assigning the color value to the first pixel in the second visualization layer;
generating a second heatmap of the first region-of-interest for the second time period based on the second visualization layer and the commissioning image; and
in response to identifying the second frequency of presence of the human object type falling below the frequency of presence of the human object type intersecting the first pixel:
highlighting the first pixel in the second heatmap as a deviation of the human object type between the first heatmap and the second heatmap;
generating a prompt for an user to investigate the deviation of the human object type between the first heatmap and the second heatmap; and
serving the prompt, the first heatmap, and the second heatmap to the user.
