1. A method for analyzing a crowd using a plurality of images captured by an aerial drone, the method comprising:

  • determining a geographic area associated with the crowd;

    partitioning the determined geographic area into a plurality of zones;

    determining a flight path covering each zone within the plurality of zones;

    sending the determined flight path to the aerial drone;

    flying, by the aerial drone, along the sent flight path;

    generating, by the aerial drone, the plurality of images, and a plurality of drone position data that comprises a drone location, a drone orientation, and a photographed location;

    receiving the plurality of images and the plurality of drone position data from the aerial drone;

    analyzing the received plurality of images to identify a plurality of individuals associated with the crowd, wherein analyzing the received plurality of images to identify the plurality of individuals associated with the crowd further comprises cropping each image within the received plurality of images to create an image partition for each identified individual within the identified plurality of individuals;

    determining an individual position for each identified individual within the identified plurality of individuals based on the analyzed plurality of images and the received plurality of drone position data;

    determining an individual movement vector for each identified individual within the identified plurality of individuals based on tracking changes in the determined individual position associated with the individual as captured within the analyzed plurality of images;

    predicting a plurality of individual characteristics for each identified individual based on the analyzed plurality of images, wherein predicting the plurality of individual characteristics comprises using a pre-trained machine learning model to process the analyzed plurality of images and predict the plurality of individual characteristics, and wherein the predicted plurality of individual characteristics includes a plurality of demographic characteristics and a plurality of physical characteristics;

    predicting a plurality of crowd characteristics based on the predicted plurality of individual characteristics for the plurality of identified individuals, wherein the predicted plurality of crowd characteristics includes an aggregate motion characteristic determined based on the determined individual movement vector for each identified individual and a rate of entry and a rate of exit corresponding with each zone within the plurality of zones, and wherein the predicted plurality of crowd characteristics includes a crowd concentration characteristic based on the determined individual position for each identified individual; and

    determining a placement and a duration for dynamic advertising to distribute to the crowd based on the predicted plurality of crowd characteristics.
