摘要

A data extraction unit (23): extracts image data of a region that includes a detection target region as target data from image data obtained as a result of a photography device (41) photographing a photography region; and extracts image data of an enlarged region as partial data from the target data. A size modification unit (24) modifies the size of each of the target data and the partial data to a required size that is required by an object detection model that is a model for detecting objects from image data. An object detection unit (25) inputs each of the size-modified target data and partial data into the object detection model and detects a target object from each of the target data and the partial data.
