FEATURE POINT EXTRACTION DEVICE, FEATURE POINT EXTRACTION METHOD, AND PROGRAM STORAGE MEDIUM

摘要

A feature point extraction device has a following configuration to extract a feature point of an object from an image and suppress an increase in a calculation amount even in a case where an inclination of the object included in the image is large. The feature point extraction device includes a reduction unit, a first extraction unit, a correction unit, and a second extraction unit. The reduction unit reduces a data amount of an image. The first extraction unit extracts a feature point of the object included in the image from the image of which the data amount is reduced. The correction unit corrects an inclination of the object in an image before the data amount is reduced using the feature point extracted by the first extraction unit. The second extraction unit extracts a feature point of the object from the image of which the inclination is corrected.
