Method of identifying and displaying areas of lodged crops

Abstract

A three-dimensional surface of the upper cover of the crops is recognized and recorded by a contactless scanning from above the field; a referential height h of the crop's stem is determined and the three-dimensional surface of the field from which the crops grow is determined. A reached height x of the vegetation for the individual points is computed by comparison of the three-dimensional surface of the upper cover of the crops with the three-dimensional surface of the field, whereby in case the reached height x of the vegetation is smaller than the referential height h of the crop's stem this difference between the reached height x of the vegetation and the referential height h of the stem determines in a given point of the field the angle β of lodging pursuant to the goniometric function. A classification of the grains into classes depending on the angle α of the slope of the lodged grain in interval 0° to 90° is realized, whereby this results in computation of the heights (h) of the grain spikes pursuant to relation x(0 to n)=h·sin α(0 to n) for the creation of the digital vector map with the customizable levels of the lodging of the grains.
