Sensor data array and method of counting occupants

A method comprising:

• receiving, by a processor from a plurality of sensors, a sequence of data indicative of a presence of a person in an area of interest within a field of view of the plurality of sensors;
• determining, by the processor, an estimate of background level information for the area of interest in an instance of an absence of a person in the area of interest;
• applying a noise-reducing filter to the received sequence of data indicative of a presence of a person in the area of interest;
• generating, by the processor, one or more probabilities of a person being located in the area of interest based on a combination of the determined background level information and the filtered sequence of data;
• and
• determining an initial occupancy of a person in the area of interest based on the received sequence of data indicative of a presence, wherein the plurality of sensors detect a thermal energy emission and the filtered sequence of data includes data representative of the detected thermal energy emissions that is used to determine an on-going occupancy of a person in the area of interest.

A system comprising

• a memory storing processor-executable instructions;
• and
• one or more processors to execute the processor-executable instructions to:
• receive, from a plurality of sensors, a sequence of data indicative of a presence of a person in an area of interest within a field of view of the plurality of sensors;
• determine an estimate of background level information for the area of interest in an instance of an absence of a person in the area of interest;
• generate one or more probabilities of a person being located in the area of interest based on a combination of the determined background level information and the sequence of data indicative of a presence of a person in the area of interest;
• determine a number of centroids in the area of interest based on an execution of a clustering process applied to the generated one or more probabilities, the clustering process executed to determine an optimized total number of centroids for a dataset;
• and
• transmit a count of persons in the area of interest based on the determined total number of centroids that are indicative of a person.
