Title: Improved yield estimation for the Australian wine industry

Theme: New research

Date: Thursday, 23 November 2017

Time: 11,30 am Australian Central Daylight Time (Adelaide, GMT+10:30)

Duration: 30-45 minutes

Speaker: Dr Mark Whitty – Lecturer at UNSW


Yield estimation for winegrapes is a challenging problem as there can be large variability from year to year in yield components, weather conditions and management actions. This webinar will present the results from a three-year Wine Australia funded study into block-level yield estimation, whereby several image processing based methods have been designed, implemented and evaluated in Australian vineyard blocks. A system of shoot counting in combination with mobile phone images of inflorescences and bunches was shown to outperform best-practice manual yield estimation at all points during the season. This opens the possibility of using simple tools across industry to reduce the tedium of performing forecasts, improve forecasting accuracy and implement management actions to optimise yield.
