1. A guidance processing system comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to perform:
analyzing surveillance images to acquire a state of a crowd in a target area;
detecting a change in the state of the crowd in the target area;
detecting an abnormal state of the crowd on the basis of the detected change in the state of the crowd;
detecting a degree of abnormality of the crowd on the basis of the number of people causing the change of the state of the crowd, the state including at least one of a state where the people turn around and a state where the people start running;
comparing the degree of abnormality of the crowd in the target area with a degree of abnormality of a crowd in another area;
in response to determining that the degree of abnormality of the crowd in the target area severely differs from the degree of abnormality of the crowd in the another area,
generating guidance information corresponding to the target area; and
outputting the guidance information on a display device.
