High Resolution Imaging applied to high Throughput Field Apple Phenotyping (HiRI-FAP)

Improvement of using multispectral and thermal high-resolution images acquired onboard Unmanned Arerial Vehicles (UAV) for field phenotyping purposes: studying the response of plant perennials (apple trees) to hydric constraints on the Diaphen scientific platform and in professional experimental stations

Abstract

Results

The HiriFAP project made it possible to develop a methodology of high-throughput phentoyping based on airborne high-resolution imagery performed by UAV flights over apple plant groves submitted to variable hydric regimes. The HiriFAP project allowed us to validate (i) a flight procedure and image harvesting, thanks to programming RGB and NIR snapshots, and thermal-IR video; (ii) extraction of fix thermal IR images from video files, geometric and radiometric corrections of images, geolocation and mosaicking; (iii) extraction of multispectral data from image files; (iv) computation of vegetation and stress indices from these data; (v) relation of indices to the phenotypic variables acquired at ground level, in planta. The potential added value of an image post-treatment, consisting in image supervised classification is currently studied. Publication of the project results has been actively undertaken in front of different scientific audiences.

Perspectives

Since Hiri-FAP project produced real methodological breakthrough, transfer in professional context is currently undertaken. This consists of Aliage-fruits Casdar program (2014-2017), which aims at achieving a pre- and post-treatment pipeline dedicated to images acquired and assessing feasability of imagery procedures in professional conext.
