Abstract

The apparatus includes an optical system of selective wavelength and a computer with a memory data bank of previously stored reference values. An illumination source covering the wavelength range used is pref. provided. The system can learn to identify plants and eventually select suitable cultivation procedures. The light frequency range, green to UV and relevant to plants which corresponds to the visual range of bees, is used to obtain an absorption line spectral curve, which can be compared with the stored values.

Description

Das System kann Pflanzen dadurch unterscheiden , daß der Molekülaufbau unterschiedlich ist, und somit unterschiedliche Absorptionslinien vorhanden sind. Es wird eine geeignete Strahlquelle mit Hauptemission im Bereich "grün 500 nm UV" eingesetzt, um eine möglichst aussagefähige Meßkurve zu erzielen.The system can distinguish plants in that the molecular structure is different, and thus different absorption lines are present. A suitable radiation source with a main emission in the range "green 500 nm UV "is used to achieve the most meaningful measurement curve possible.

Diese Kurven sind außerdem nutzbar, um eine Aussage über die Düngung und den Pflanzenzustand des Feldes zu erhalten.These curves can also be used to make a statement about the fertilization and the Preserve plant condition of the field.

Das Gerät besteht aus einer Optik mit selektiver Messung der Spektrallinien, einem Rechner und wahlweise einer Beleuchtung im nutzbaren Spektralbereich.The device consists of an optic with selective measurement of the spectral lines, one Computer and optionally lighting in the usable spectral range.

Die Spektrallinien werden vor dem Start auf dem Feld eingelesen (gelernt). Das Gerät wird zur Unterscheidung von Nutzpflanzen und Unkraut eingesetzt.The spectral lines are read (learned) on the field before starting. The Device is used to distinguish between crops and weeds.
