Estimation of crop plant density with Reach RS+

Hey guys! Our users from Australia conducted a series of field experiments and developed a method to estimate crop plant density using UAV imagery. It’s an interesting project so we decided to share it with you!

Group of scientists utilized Reach RS+ to place ground control points (GCPs) with sub-centimeter accuracy.

Images were taken with a 3DR Solo and then imported into Pix4D to generate an orthomosaic. A field map was created in ArcGIS to summarize the total number of safflower seedlings.

The accuracy of the method was evaluated by comparing plant counts obtained by manual counting to those estimated digitally. The model performed well and now can be used for plant density estimation across various crop species.

There is DJI drone on Photo. Not 3dr solo.

I think the photo in the is just for posing. In the article itself, the 3dr is indeed mentioned.

The study uses the 3DR Solo but scientists have a range of UAVs, from small to large such as DJI M600 pro. In this photo, you can see a DJI M100.
