PROBLEM TO BE SOLVED: To solve a problem of an object detection device detecting an object from a voting result about a plurality of feature points appearing in an image of the object, wherein high-accuracy detection is difficult because a difference between votes caused by the likelihood of variation of the feature points occurs.SOLUTION: A detection storage part 12 stores information about a feature point distribution in an object image and a relative position of a reference point from a representative position of the feature point distribution as feature point information 120. A vote part 141 obtains, in the input image, a voting value of a feature point in each position of the input image according to the feature point distribution moved such that the representative position accords with the relative reference point provided in the relative position of a detection position of the feature point. An object decision part 142 determines a position of the reference point inside the input image based on a point wherein a total value of voting values of the respective feature points in the respective positions of the input image exceeds a prescribed detection threshold value and becomes locally maximal, and determines that the object image is present in the position. |
