Method for supporting a camera-based environment recognition by a means of transport using road wetness information from a first ultrasonic sensor

An apparatus for supporting a camera-based environment recognition by a transport device using road wetness information from a first ultrasonic sensor, comprising:

• an evaluation unit;
• and
• a data input;
• wherein the evaluation unit is configured to, in conduction with the data input:
• record a first signal representing an environment of the transport device determined by the first ultrasonic sensor of the transport device;
• record a second signal representing the environment of the transport device determined by a camera of the transport device;
• ascertain the road wetness information based on the first signal, wherein the road wetness information is ascertained by comparing a noise level of the first signal to a velocity-dependent predefined threshold value of a plurality of predefined threshold values, wherein the plurality of predefined threshold values are based on a velocity range;
• select a predefined set of parameters from a plurality of predefined sets of parameters as a function of the road wetness information;
• and
• performing an environment recognition based on the second signal in conjunction with the selected predefined set of parameters.
