Building three-dimensional point clouds from high-resolution photos taken from unmanned aerial vehicles or drones may soon help plant breeders and agronomists save time and money compared with measuring crops manually. Crop researchers and breeders need two types of data when determining what crop improvement selections to make: genetic and phenotypic, which are the physical characteristics of the plant. Great strides have been made in genetics, he said, but there's still much work to be done in measuring the physical traits of any crop in a timely and efficient manner. Currently, most measurements are taken from the ground by walking through fields and measuring.
