    Abstract: The method involves detecting a considered mark repeated along length of a road (203), on an image acquired by a camera (201) e.g. radar, where the mark is formed of elements at a position. Another mark is detected at a remote distance from a vehicle (200), where the mark is presented at another position on road. A determination is made whether change of orientation of the marks exists by an image processing application. Presence of a slope (204) is deduced from the change of marks orientation and a gradient of the slope is calculated from characteristics of the change of marks orientation. An independent claim is also included for a driving assistance device embarked within a vehicle, for determining gradient of a slope, comprising a camera.
