This speed calculating device for calculating the speed of an object in the perimeter of a moving body is provided with: an image detection unit which images the perimeter of the moving body and detects objects by means of the imaged images; and a speed calculation unit which calculates the speed of an object by utilizing, in a proportion corresponding to the distance from the moving body to the object, the moving body speed, which indicates the speed of the moving body, and the image speed, which indicates the speed of the object and is calculated from the images; specifically, the speed of the object is calculated using the moving body speed and the image speed in a proportion in which the greater the distance to the object, the higher the ratio of the moving body speed, and the smaller the distance to the object, the higher the ratio of the image speed.
