Abstract
Different types of yield mapping systems for combine harvesters have been proposed in the literature. Each system is characterized by its composition of positioning system, grain flow measurement device, ground speed sensor and eventually cutting width sensors. The individual accuracy of each device has been optimised, without looking at their own impact on the accuracy of the global system.By developing a virtual harvesting process, it is possible to “harvest” virtual fields several times with different machine settings, ground speed strategies and measurement devices. Subsequently, the accuracy of different set-ups can be compared and the required accuracy for each individual measurement device can be quantified. In this way, it is possible to design a balanced composition of measurement devices for a predefined budget.
