A method for producing a masking instruction for a camera of a vehicle, the method including a setting step, a transforming step, and a storing step. In the setting step, interpolation points of a field-of-view boundary are set in a vehicle coordinate system using three-dimensional model data of the vehicle, the interpolation points being set from a camera perspective that is modeled in the model data. In the transforming step, vehicle coordinates of the interpolation points from the vehicle coordinate system are transformed into a spherical coordinate system to obtain spherical coordinates of the interpolation points. In the storing step, a mask curve defined by the interpolation points, is stored in the spherical coordinate system in order to produce the masking instruction.
