METHOD FOR DETERMINING A WEED PERCENTAGE AND AGRICULTURAL CONTROL DEVICE

摘要

A method for determining a weed percentage in a viewing section (10) of a field (20) is described. Actual spectral information is acquired by means of at least one optical viewing section sensor (12a, b) which is directed to the viewing section (10). Furthermore, reference spectral information is acquired by means of an optical reference sensor (32), which is directed to a reference section (30) of the same soil surface (22). A difference between the actual spectral information and the reference spectral information is determined. Finally, the difference is applied to the weed percentage by means of a predefined image. Furthermore, an agricultural control device (100) is described which is suitable for the implementation of the method.
