Classification: CPC A  G | IPC A  G

Claim 18:
19. A method for controlling the operation of an attachment, comprising:
coupling the attachment to a tractor via a power lift comprising two lower link arms;
detecting a pull point as a geometrical intersection of imaginary extensions of both lower link arms based on reference angles, where the imaginary extensions of the lower link arms enclose with a reference straight line;
determining the reference angles by an optical capture of the lower link arms;
controlling the operation based on the detected pull point;
processing the image data in a data processing unit, the output signals of which represent the reference angles; and
providing the image processing unit with at least one neural network for processing the image data;
wherein output data of a neural network represents a classified binary image of the image data or a value of the respective reference angle.
