Going off a similar principal to Green on Brown weed mapping, Pix4D Field’s “Magic Tool”is another great feature becoming utilized in the spray drone world. The Magic tool uses AI to Detect weeds of similar colour for spot spraying applications.
By using Red, Blue and Green (RGB) map imagery, special boundary layers are created designating the Spray and non-spray areas.
Once this file is uploaded onto a spray drone, it will execute the mission with RTK centremetre precision.
The advantages of spot spraying weeds to this level of precision are huge! as it results in less chemical usage, which saves money. It takes less time to spray because the drone is only spot treating where needed.
Also, it reduces the risk of weed resistance which is common with Blanket spraying whole areas, whether weeds are present or not!
