Calibration adjustment for agricultural sprayer with real-time, on-machine target sensor

An agricultural system, comprising:

• an agricultural sprayer;
• a spray nozzle mounted to the agricultural sprayer;
• an optical sensor sensing an image of a portion of a field ahead of the spray nozzle in a direction of travel of the agricultural sprayer;
• a target identification system detecting a visual marker in the image, the visual marker having a marker type and marking a marked area in the field, the target identification system generating a target identification result indicative of whether the marked area includes a target of the agricultural sprayer, wherein the visual marker comprises an artificial marker positioned at a location corresponding to the marked area in the field;
• a result generation system determining a target identification accuracy based on the target identification result and the marker type;
• an adjustment processor identifying a machine adjustment based on the target identification accuracy;
• and
• an output system controlling the agricultural sprayer to perform a spraying operation based on the machine adjustment.

An agricultural system, comprising:

• at least one processor;
• and
• a data store storing computer executable instructions which, when executed by the at least one processor, cause the at least one processor to perform steps, comprising:
• receiving an image signal indicative of an image of a portion of a field ahead of a spray nozzle in a direction of travel of an agricultural sprayer;
• detecting an artificial visual marker in the image, the artificial visual marker having a marker type and marking a marked area in the field;
• performing target identification on the image to generate a target identification result indicative of whether the marked area includes a target of the agricultural sprayer;
• determining a target identification accuracy based on the target identification result and the marker type;
• identifying a machine adjustment based on the target identification accuracy;
• and
• controlling the agricultural sprayer to perform a spraying operation based on the machine adjustment.
