Abstract: A system for detecting properties of at least one wheel of a rail vehicle, where the system is arrangeable at at least one first rail, where the system has at least one first detection device, where the first detection device is configured to detect at least one first region of a wheel of a rail vehicle passing on the first rail; a system and a method for establishing properties of a wheel and/or a wheelset of a rail vehicle, in which the accuracy of the established properties of the wheel and/or of the wheelset is increased in comparison with systems and/or methods known from the prior art, is realized by virtue of the first detection device being a plenoptic camera.
