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 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...
متن کاملHomologous Streptomycin Resistance Gene Present among Diverse Gram-Negative Bacteria in New York State Apple Orchards.
The streptomycin resistance gene of Pseudomonas syringae pv. papulans Psp36 was cloned into Escherichia coli and used to develop a 500-bp DNA probe that is specific for streptomycin resistance in P. syringae pv. papulans. The probe is a portion of a 1-kb region shared by three different DNA clones of the resistance gene. In Southern hybridizations, the probe hybridized only with DNA isolated fr...
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 کاملIntegrated Fruit Production for New Zealand Pipfruit: Evaluation of Pest Management in a Pilot Programme
A pilot Integrated Fruit Production (IFP) programme for pest and disease management was evaluated on approximately 88 apple orchards throughout New Zealand. Insect control was based on increased use of biological control, monitoring and threshold-based applications of insecticides. The insect growth regulator tebufenozide was used for control of codling moth and leafrollers, while homopteran pe...
