BACKGROUND REFLECTANCE COMPENSATION AND ITS EFFECT ON MULTISPECTRAL LEAF SURFACE MOISTURE ASSESSMENT
Publikováno v:
Transactions of the ASAE. 48:375-383
The feasibility of using a multispectral imaging sensor for non-contact leaf wetness sensing was evaluated. The changes of spectral reflectance in the visible (400-700 nm), very-near-infrared (700-1300 nm) and near-infrared ranges (1300-2500 nm) caus

A one-dimensional imaging probe was used to measure samples of the spray distribution produced by four different rotary atomizers operating at several different flow rates and rotary speeds using tap water and vegetable oil as carriers. The operating

Spectral reflectance property of the leaves is a good indicator of the presence of spray droplets on the leaf surface. An experiment was designed to study the feasibility of detecting and quantifying the leaf surface moisture content based on the ref
