Abstract

Highlights: We investigated the possibility of estimating leaf water content (LWC) using radiometric corrected intensity data from terrestrial laser scanner (TLS). Firstly, a reflection model was used to remove specular intensity caused by leaf surface at perpendicular angle; and then reference targets were applied to correct the incidence angle effect. Results show the accuracy of the estimation of leaf water content was significantly improved after the radiometric correction (R²=0.757).
