Developing a phone-based imaging tool to inform on fruit volume and potential optimal harvest time

Research output: Book/ReportCommissioned report

Abstract

The objectives of this project were to investigate the feasibility of developing a smartphone-based imaging tool for berry quality assessment that can be conveniently used within vineyards to provide real time and in-field evaluation of grape berry size and colour. After taking a photograph of the grape bunch on the vine, the smartphone application analyses the image, detects and samples the visible berries, and determines the volume and hue distributions of the sampled berries. Results are reported for the analysis of grape bunch images from Australian vineyards. The resulting App (Called WineOz SmartGrape) is programed for use on an Android SmartPhone platform and can be downloaded from the App store using the following link:https://play.google.com/store/apps/details?id=com.nwgic.grapeyield.The App is intended to be used to monitor the spatial and temporal data collected for vineyard blocks and is best used when interfaced to a dashboard which can be downloaded from the NWGIC web site along with instructions:https://www.csu.edu.au/nwgic/research/wineoz-smartgrape-mobile-applicationChallenges and recommendations for smartphone imaging in the field are also discussed.
