Abstract
The present disclosure relates to agriculture. The teachings thereof may be embodied in methods to determine a percentage of weeds and/or control device. For example, a method for determining a weed percentage in an observation section of a field may include: acquiring actual spectral information using an optical observation section sensor aimed at the observation section; acquiring reference spectral information using an optical reference sensor aimed at a reference section of the same ground area; determining a difference between the actual spectral information and the reference spectral information; and mapping the difference to the weed percentage using predefined mapping.
Claims10
A method for determining a weed percentage in an observation section of a field, the method comprising:
- acquiring actual spectral information using an optical observation section sensor aimed at the observation section;
- acquiring reference spectral information using an optical reference sensor aimed at a reference section of the same ground area;
- determining a difference between the actual spectral information and the reference spectral information;
- and
- mapping the difference to the weed percentage using predefined mapping.
An agricultural control device (100) having
- an optical observation section sensor;
- a reference sensor receiving interface;
- an optional optical reference sensor;
- the observation section sensor and the reference sensor receiving interface fastened to a vehicle;
- a comparator connected downstream of the sensors to compare actual spectral information from the observation section sensor with reference spectral information from the optical reference sensor;
- and
- a mapping unit connected downstream of the comparator to map the comparison result from the comparator to a weed percentage and to provide the mapped result to an output of the agricultural control device.
