Performance of an Ultrasonic Ranging Sensor in Apple Tree Canopies
Electronic canopy characterization is an important issue in tree crop management. Ultrasonic and optical sensors are the most used for this purpose. The objective of this work was to assess the performance of an ultrasonic sensor under laboratory and field conditions in order to provide reliable estimations of distance measurements to apple tree canopies. To this purpose, a methodology has been...
متن کاملApple Tree Physiology – Implications for Orchard and Tree Management
INTERNATIONAL DWARF FRUIT TREE ASSOCIATION Apple yield and fruit quality are the end result of myriad cultural practices (e.g., pruning, thinning, spraying), environmental inputs (e.g., light, carbon dioxide, water, nutrient supply) and physiological processes (e.g., leaf area development, light interception, photosynthesis, respiration). All of them are truly essential contributors to fruit pr...
متن کاملApple detection in natural tree canopies from multimodal images
In this work we develop a real time system that recognizes occluded green apples within a tree canopy using infra-red and color images in order to achieve automated harvesting. Infra-red provides clues regarding the physical structure and location of the apples based on their temperature (leaves accumulate less heat and radiate faster than apples), while color images provide evidence of circula...
متن کاملRipe Fuji Apple Detection Model Analysis in Natural Tree Canopy
In this work we develop a novel approach for the automatic recognition of red Fuji apples within a tree canopy using three distinguishable color models in order to achieve automated harvesting. How to select the recognition model is important for the certain intelligent harvester employed to perform in real orchards. The L*a*b color model, HSI (Hue, Saturation and Intensity) color model and LCD...
