Agriculture drone is a hot topic these days. These unmanned aerial vehicles (UAVs) are rapidly becoming a core tool in a modern farmer’s precision equipment mix.
Today’s farmers have to deal with increasingly complex concerns. Issues such as water – both quality and quantity,climate change, glyphosate-resistant weeds, soil quality, uncertain commodity prices.Growers are turning to hightech tools, often under the banner of precision agriculture, to respond to and mitigate these and other concerns.
With complete agricultural data a farmer can spot problems early and rapidly select appropriate interventions.Spot-checking, the most common method used to get this information today, does not accurately capture conditions across an entire field. Agricultural drones
represent a new way to collect field-level data. The most compelling reason for using drones is that the results are on-demand; whenever and wherever needed, drone can be easily and quickly deployed.
To really obtain value from an agricultural drone, however, sensors must be considered, as well as tools to fly the drone in a pattern over the entire field and software to combine the sensor readings across the field
into a single layer that is then analyzed and geo-referenced.
Data Processing and Analysis
When a drone collects data over a field, the camera takes several hundred still images as it flies a “lawnmower” pattern back and forth across the field.
These images then performed to make the results useful.A computer with specialized software can process the images locally, which can be time consuming on several levels. Gaining mastery of the software initially and achieving repeatable results, flight after flight, can be a steep learning curve. The processing itself can tie up the computer for hours each time new data is loaded, suppressing productivity and requiring the operator to be present to monitor progress.Alternatively, processing can be done using a purpose-built, web-based service. In this model, the operator performs the flight, runs software that automates image collection, and uploads to the cloud.
Pesticide spraying and precise farming
With the development of the flight control and GPS positioning function, agricultural drones are nowadays can finish the spraying precisely with centimeter grade accuracy, which can efficiently avoid the repeated spraying and missed spraying. With sensors and other external equipments, drones has pesticide tanks and accurate pesticide spraying flow control system, which can realize the different dosage and spraying result on various fields with different pesticides and aiming at different insects.
