A method for determining the movement state of a rail vehicle wheel relative to the rail traversed by the wheel includes capturing successive images of a wheel-rail region using a camera focused on the wheel-rail region. The wheel-rail region contains at least one wheel sub-region and at least one rail sub-region traversed by the wheel. A region along which the sub-regions of the wheel and the rail contact each other is ascertained in the images. Characteristic points are ascertained in the rail and wheel sub-regions of a first image. The characteristic points are uniquely optically recognizable in the first and successive images. Respective distances from the characteristic points to the contact region are determined for successive images, and the movement state of the wheel is determined from a change in distance from the characteristic points to the contact region resulting over the successive images.
