Establishment for recognizing and differentiating plants and soil areas as well as for distinguishing crops and wild plants

摘要

An optical method involving natural light and infrared radiation reflection and emission is used to distinguish between the ground (5) and the plants (4a,4b). Different water evaporation is used at equal and different temp. The different intensities arising from the ground and plants are detected by optical sensors (1) mounted on an operating device.The ground-plant difference and the identities and locations of the different plants are derived from the intensities. The identified plants are specifically treated, whereby a unit associated with a sensor is activated by an electronic or hydraulic control unit to deliver material to the plant.
