Abstract
The present invention relates to a method for calibrating an agricultural spraying machine comprising a plurality of spray nozzles arranged on the spray boom, at least one optical sensor and a control system, each optical sensor of said at least one optical sensor having a field of view comprising sectors, each of the sectors being associated with a spray nozzle, the control system being configured to control the plurality of spray nozzles as a function of images acquired by the optical sensors, the calibration method comprising, for an optical sensor, an automatic association implemented by the control system of each sector of the field of view of the corresponding optical sensor with a spray nozzle of the plurality of spray nozzles.

A calibration method of an agricultural spraying machine comprising a spraying system comprising a spray boom, a plurality of spray nozzles arranged on the spray boom one or more optical sensors, and a control system, each of the one or more optical sensors having a field of view comprising sectors forming a grid, each cell of the grid of each sector being associated with a spray nozzle of the plurality of spray nozzles, each of the spray nozzles associated with one or more cells of the grid, the control system being configured to process acquired images of the field of view of each of said one or more optical sensors and to control the plurality of spray nozzles as a function of said images, the calibration method comprising, for each optical sensor, using the control system to automatically associate each sector of the field of view with at least one of the plurality of spray nozzles.
An agricultural spraying machine comprising a spraying system comprising a spray boom, a plurality of spray nozzles arranged on the spray boom, a plurality of optical sensors, and a control system, each optical sensor of said plurality of optical sensors having a field of view comprising sectors forming a grid, each cell of the grid of each sector being associated with a spray nozzle of the plurality of spray nozzles, each of the spray nozzles being associated with one or more cells of the grid, the control system being configured to process acquired images of the field of view of each of said optical sensors and to control the plurality of spray nozzles as a function of said images, the control system being configured to carry out, for each optical sensor of said plurality of optical sensors, an automatic association between each sector of the field of view of the optical sensor with at least one of the plurality of spray nozzles.
An agricultural spraying machine comprising:
- a spraying system comprising a spray boom comprising a frame having a length;
- a plurality of spray nozzles arranged along the length of the spray boom,
- a plurality of optical sensors arranged on the length of the spray boom;
- and
- a control system spaced from the spray boom;
- each optical sensor of said plurality of optical sensors having a field of view comprising sectors and cells forming a grid;
- each of the spray nozzles associated with one or more cells of the grid;
- wherein the control system is configured to process acquired images of the field of view of each of said optical sensors and to control the plurality of spray nozzles as a function of said images;
- and
- wherein the control system is configured to carry out, for each optical sensor of said plurality of optical sensors, an automatic association between each sector of the field of view of the optical sensor with at least one of the plurality of spray nozzles.
