Abstract: A method for classifying plants. In the method, the plants or their plant components are detected within an evaluation region at a first evaluation point in time with the aid of an optical and/or infrared detection unit, and the detected image data of the detection unit are evaluated with the aid of an algorithm. Using the evaluation, it is possible to distinguish at least one first plant type from at least one second plant type. The second plant type being treated in particular with a medium, preferably a liquid spray.

Abstract: A method for applying a spray agent to an agricultural land using a spray nozzle unit of an agricultural spray device. The method includes detecting first and second field sections of the agricultural land using an optical detection unit to obtain first and second pieces of image information from the first and second field sections, wherein the pieces of image information have a common lateral overlapping area having a depth in the travel direction of the agricultural spray device; classifying plants in the obtained pieces of image information using a control unit; determining first and second plant identification numbers for first and second image evaluation areas in the obtained first and second pieces of image information using the classified plants; and applying the spray agent as a function of the determined plant identification numbers using the spray nozzle unit of the agricultural spray device.

Abstract: A method for calibrating a camera. The method includes inputting a raw camera image, the raw camera image having a plurality of pixels, each pixel having a gray-scale value out of a plurality of gray-scale values. A first quantity of pixel gray-scale values that are above a maximum gray-scale value limit is compared with a first frequency. A current gain of the camera is adjusted to a new gain if the first quantity exceeds the first frequency. A second quantity of pixel gray-scale values that are above a minimum gray-scale value limit is compared with a second frequency if the first quantity does not exceed the first frequency. The current gain and a current exposure of the camera are retained if the second quantity is not below the second frequency. The current exposure is adjusted to a new exposure if the second quantity is below the second frequency.

Abstract: A method for classifying plants for agricultural purposes. The method includes: detecting a field section having plants using an optical detection unit inclined toward the field section to obtain image information having a rear image edge having an image width and a front image edge having a larger image width; classifying the plants in the image information into first and second plant classes using an algorithm to treat the plants of the second plant class with a liquid spray agent, in accordance with the classification. The step of classifying comprises a step of reclassifying, in which classified plants are reclassified from the second plant class to the first plant class using the algorithm if they extend in a rear image section of the image information defined by a defined image separation line from a lateral image edge of the image information maximally up to a defined reclassification boundary line.
