A method for ascertaining a liquid depth of a liquid accumulation on a travel path of a vehicle, in particular in front of a vehicle. The method comprises the following steps: reading in a current image of a vehicle-external region of the travel path, detected by an image detection device in particular of the vehicle, in which a detected liquid accumulation is present, and ascertaining the liquid depth of the liquid accumulation by comparing the current image with an image that is stored in a storage device and represents the vehicle-external region without a liquid accumulation.
