PROBLEM TO BE SOLVED: To provide an angle-of-view deviation correction device capable of detecting an angle-of-view deviation due to an annual change after instillation of a camera, and achieving an estimation of an angle-of-view deviation.SOLUTION: An angle-of-view deviation correction device 1 corrects an angle-of-view deviation of a camera by using a reference image obtained by photographing a predetermined place with the camera and an object image obtained by photographing the place similar to the reference image. The angle-of-view deviation correction device includes: an edge extraction part 20 that extracts an edge of the reference image and the object image; a difference image generation part 50 that generates a difference image constructed at a difference absolute value of each pixel by using the edge extraction images of the reference image and the object image; deviation amount evaluation part 70 that calculates a deviation amount, on the basis of the deviation image, of which an evaluation value becomes the smallest value as that the sum of absolute values of the deviation value included in each pixel; and an image correction part 80 that corrects the angle-of-view deviation of object image on the basis of the calculated deviation amount.SELECTED DRAWING: Figure 1 |
