Methods and systems for forecasting crowd dynamics

A computer system for modeling crowd movement at physical venues, comprising:

• one or more processors;
• memory;
• and
• one or more programs stored in the memory and configured for execution by the one or more processors, the one or more programs comprising instructions for:
• obtaining a temporal sequence of images of a physical venue;
• for each of the images, subdividing the respective image into a respective set of logical pixels according to a predetermined mapping;
• for each logical pixel of each image, computing a respective crowd density representing a respective number of mobile objects per unit of area in the physical venue at the logical pixel, thereby forming a temporal sequence of crowd density maps corresponding to the temporal sequence of images;
• and
• using successive pairs of crowd density maps to train a model on spatiotemporal changes in crowd density at the physical venue.

A non-transitory computer readable storage medium storing one or more programs configured for execution by a computer system having one or more processors, memory, and a display, the one or more programs comprising instructions for:

• obtaining a temporal sequence of images of a physical venue;
• for each of the images, subdividing the respective image into a respective set of logical pixels according to a predetermined mapping;
• for each logical pixel of each image, computing a respective crowd density representing a respective number of mobile objects per unit of area in the physical venue at the logical pixel, thereby forming a temporal sequence of crowd density maps corresponding to the temporal sequence of images;
• and
• using successive pairs of crowd density maps to train a model on spatiotemporal changes in crowd density at the physical venue.
