1. A queue analysis apparatus, comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to perform operations comprising:
estimating a position and an orientation of an object included in a target image;
generating, for a queue region being a region including a queue of an object in the target image, a queue line representing a queue included in the queue region by a line, based on the position and the orientation being estimated for the object included in the queue region; and
generating output information including a result image in which the queue line is included, wherein
the result image is acquired by superimposing the queue line on any one of the target image, a background image in which a same range as that of the target image is included, and a map image in which a same range as that of the target image is included, and
the operations further comprise:
estimating a time change in a queue line, based on the queue line generated from the target image and a queue line generated in the past for a queue represented by the queue line;
generating a future queue line for the queue, based on the estimated time change in the queue line; and
including the generated future queue line in the result image.
