Collaborative project (Brittany Region)
A project aimed at assessing the performance of near-field remote sensing measurements for plant characterisation (e.g. estimation of chlorophyll content, quantification of the plant area index (PAI), etc.). The goal is to mount photonic instruments on UAVs. Two optical paths are being studied: an active path (multispectral lidar) and a passive path (hyperspectral imaging).
Our objective: To design and build the multispectral lidar (12 bands in the visible and infrared, 550 nm – 1650 nm) for in-situ measurement of leaf reflectance. Two field measurement campaigns validated the measurement instruments and the feasibility of characterising the plant cover (maize and wheat). This work has been presented in a number of scientific papers [9th Colloquium of the Hyperspectral Group (SFPT-GH, 2024) and Optique Rouen (SFO, 2024)].
