Tutorial for Weed Detection
Setting up the Data
Download the sample imagery for this tutorial by contacting Solvi : support@solvi.ag
Assuming you have already created your first ‘Farm’ within Solvi, select ‘Upload Images’, then ‘Stitched Map’ and navigate to the sample imagery location.
Populate the ‘Field’ and ‘Crop’ values, then select ‘Upload 1 Image’. Allow the upload and processing to complete.
Open the project within the ‘Imagery’ tab then define the Field Boundary. (This will make further processing more efficient)
NOTE If you are working over a particularly large area, then the processing stages are likely to take a long time. This being the case, we can recommend you reduce the field perimeter to a smaller area at first to test your AI model. Once successful, you can reset the boundaries.
Running the Weed Detection PlantAI Tool
Navigate to the ‘Analysis’ tab, select ‘PlantAI’ and choose to create a new detection. Select ‘Weed Detection’. The ‘Provide Examples’ setup will appear
Zoom into the orthomosaic image and using the polygon or circle tool, draw a perimeter around 3 plant specimens (weeds). A perimeter box will then appear automatically afterward.
Note that it is best to use the polygon tool in those cases where the plant has an irregular shape.
Keep going until all the weeds within the bounding box have been selected. Then when you are ready, select ‘Continue’. Then select ‘Run Test Detection’. The processing window will appear and will take some time to complete.
The Review Test Results screen will be displayed where a manual inspection of the detection accuracy is required.
If there are any weeds that have not been properly detected, zoom into this area, select ‘Provide more examples’ then select ‘add examples’. And rerun the test detection.
Continue this process of improving the detection until the test area detects all weeds correctly. Once you are satisfied with the results, then click on ‘Continue with the whole field’.
Review field boundaries and price summary, adjusting the boundaries if necessary to avoid processing of irrelevant areas. When ready, click ‘Run Detection’. The processing will now begin for the whole area and will take some time to complete.
The finished result will be displayed within the viewer. You can now export this to a shapefile for prescription.
Congratulations! You have now reached the end of this weed detection tutorial.
