Bird detection device, bird detection system, bird detection method, and program extracting a difference between the corrected images

摘要

A bird detection device equipped with: a captured image acquisition unit that acquires a captured image; a bird candidate image extraction unit that extracts a bird candidate image, which is a candidate bird image, from the captured image; and a bird detection determination unit that, on the basis of the time required for the bird candidate image to move in accordance with the size of the bird candidate image in the captured image, determines whether a bird has been detected. The bird detection determination unit also can determine whether a bird has been detected on the basis of the degree of change in the shape of the bird candidate image for a prescribed time interval.
