Drones for sugarcane
In a typical, 20-minute flight, a drone will take around 10,000 photographs from a systematic grid pattern using predetermined track width, overlap and vertical or oblique look angles.
The photographs are geotagged and recorded in a memory card in the camera. The memory card is transferred to a computer or laptop with specialised software. The software ‘stitches’ all the photographs together to generate point clouds, digital surfaces and terrain models and ortho-mosaics from which volumes, angles and distances can be readily measured.
Once processed, the farmer knows exactly where the problem areas are and can take whatever remedial action is warranted.
