On ecological as well as economical grounds, mechanical weeding is once again increasingly applied. However, automatic steering of the cultivator is needed. Described in this paper is a system that delivers data for the steering system with the required accuracy. Photos of the maize crop are taken by video camera and these are digitalised and processed. Through the system s pre-processing the deviations of the actual position of the cultivating implement from the ideal position can be determined.      «
