Robotic Surveying of Apple Orchards
We present a novel system for surveying apple orchards by counting apples and estimating apple diameters. Existing surveying systems resort to active sensors, or high-resolution close-up images under controlled lighting conditions. The main novelty of our system is the use of a traditional low resolution stereo-system mounted on a small aerial vehicle. Vision processing in this set up is challe...
متن کاملSusceptibility of the European earwig, Forficula auricularia, to insecticide residues on apple leaves
The European earwig (Forficula auricularia) is potentially a predator of a number of insect pests in apple orchards. However, its effectiveness as a natural enemy in apple orchards may be compromised by insecticide sprays. A laboratory bioassay of eight insecticides currently used in Integrated Fruit Production (IFP) apple orchards and one as-yet unregistered product was undertaken to determine...
متن کاملAutomated Crop Yield Estimation for Apple Orchards
Crop yield estimation is an important task in apple orchard management. The current manual sampling-based yield estimation is time-consuming, labor-intensive and inaccurate. To deal with this challenge, we developed a computer vision-based system for automated, rapid and accurate yield estimation. The system uses a two-camera stereo rig for image acquisition. It works at nighttime with controll...
متن کاملBait Stations for Controlling Voles in Apple Orchards
Bait stations made with polyvinylchloride (PVC) pipe were compared with hand-broadcast applications of rodenticides for achieving long-term control of pine and meadow vole populations (Microtus pinetorum and M. pennsylvanicus, respectively) in two apple orchards in the mid-Hudson Valley of New York. The stations were constructed of three pieces of 1.5-in diameter PVC tubing joined together in t...
متن کاملAssessment of Phylloplane Micro-organism Populations in Canterbury Apple Orchards
Micro-organism populations on the leaf surface can be an indicator of environmental health in orchards. A method was developed to detect changes in these populations in apple orchards. Firstly, the variation within orchards was investigated by sampling leaves from seven locations within four trees in spring and autumn. The population density and species richness of micro-organisms when grown on...
