Researchers studying sorghum plants as a biofuel source are turning to drones as a way of quickly and efficiently collecting data about their crops, reports MIT. The drone surveillance program for plants is being developed by Carnegie-Mellon spinoff Near Earth Autonomy, a company known for its smart drone technology that combines sensors and software to make a drone capable of recording and analyzing its surroundings.
Funded by a grant from the Department of Energy’s Advanced Research Projects Agency-Energy program (ARPA-E), Near Earth Autonomy is trying to accelerate the process of phenotyping sorghum plants in the field, which is traditionally completed using plant breeders who manually survey the crop. These breeders are looking for the proverbial needle in the haystack — a single plant capable of exceptional growth in a 10-acre crop of mixed growth plants. Near Earth Autonomy has developed a drone-powered system that will significantly reduce the manpower and work hours needed to identify these super-strains of sorghum: a 25-pound autonomous helicopter that is programmed to interact with automated sensors in the field.
Each aerial drone in this project is equipped with a LIDAR unit, visible imaging gear, and cameras that can capture thermal, infrared, and hyperspectral images. The UAV-based system is capable of measuring plant characteristics such as height, stalk thickness, leaf angle, and more.
