The invention relates to a device (100) for measuring speed and/or position of a vehicle (200) moving along a guidance track, by day and by night, and doing so whatever the climatic conditions. According to the invention, such a device comprises: - at least one image capture apparatus (4) delivering a sequence of digital images of an environment of said vehicle (200); - means for determining the apparent motion of at least one visual index, called a primitive, between two images delivered by said image capture apparatus (4), so as to determine the apparent motion of said at least one visual index; - means of estimating speed and/or the position of said vehicle (200) on the basis of said apparent motion of said at least one visual index.
