摘要： The invention concerns a method using a robot for an automatic treatment of a weed, the method comprises steps of capturing images of said weed with a camera on said robot; determining with said images a distance between the weed and a second vegetable organism; and selecting a treatment tool of said robot for a treatment of the weed from a group of treatment tools as function of said distance.The invention further concerns a robotic vehicle for carrying out the method for an automatic treatment of a weed.

摘要： The present invention relates to an agricultural system for spraying an area of a cultivated field, including a spraying equipment. The spraying equipment comprises a first and a second supporting structures extending perpendicularly to the travel direction of the agricultural system when operating. The first supporting structure comprises a first array of nozzles separated from each other by a first distance while the second supporting structure comprises a second array of nozzles separated from each other by a second distance smaller than the first distance. The spatial resolution of spot sprays that may be sprayed by the second array of nozzles is higher than the spatial resolution of spot sprays that may be sprayed by the first array of nozzles when the first and second supporting structures are at the same height such that the first and second arrays of nozzles may perform respectively low and high-resolution spot sprays.

摘要： The present invention relates to a method of selectively spraying an area of a cultivated field (10) with an agriculture spraying vehicle. The vehicle comprises a spraying equipment (200) having at least one imaging system (210), and at least one trailing spray bar (300) comprising a plurality of electromechanical nozzles (310) spaced apart from each other by a constant pitch distance. The plurality of electromechanical nozzles (310) includes a corresponding plurality of nozzles (314) and of electromechanical valves (312). The agriculture spraying equipment (200) further comprises a control unit (220) including a processing unit to control the electromechanical valve (312) of each electromechanical nozzle (310). The method comprises: i) acquiring, by the at least one imaging system (210), an image of an area of the cultivated field (10) and differentiating on the image, by the processing unit, a plant (14) to be sprayed from a plant (12) which shall not be sprayed; ii) determining at least one nozzle (350) which is about to be substantially vertically positioned above a plant (14) to be sprayed; iii) computing a spraying pattern on the area based on the divergence angle of said at least one nozzle (350) and the vertical distance between said nozzle (350) and said area to be selectively sprayed, said spraying pattern covering the plant (14) to be sprayed and possibly touching a plant (12) which shall not be sprayed; iv) computing a distance called the jet shift distance (354) to laterally shift the spraying pattern such that the shifted pattern covers the plant (14) to be sprayed without covering the plant (12) which shall not be sprayed, and express said jet shift distance (354) as a multiple of said nozzle-to-nozzle pitch, and v) laterally shifting said spraying pattern by shifting the at least one nozzle (350) vertically positioned above a plant to be sprayed (14) by said jet shift distance (354) so that the spraying pattern from the at least one newly selected nozzle (352) does not spray the plant that shall not be sprayed (12).
