1. A patient monitoring system for monitoring a patient area, the system comprising:

  • a sensor configured to output a plurality of frames, the plurality of frames containing three dimensional information of the patient area, wherein the three dimensional information comprises a plurality of pixels;

    a user interface; and

    control circuitry configured to;

    receive the three dimensional information of the plurality of frames;

    identify a location of a patient support surface based on the three dimensional information;

    separate the plurality of pixels into a first set and a second set based on the pixels of the first set being above the patient support surface and the pixels of the second set not being above the patient support surface;

    set at least one threshold, each of the at least one threshold comprising a two dimensional plane, each of the at least one threshold set at a respective location based on the location of the patient support surface;

    identify one or more patient locations based on the three dimensional information;

    compare the one or more patient locations to the at least one threshold; and

    generate an output with the user interface based on the one or more patient locations traversing the at least one threshold.
