Abstract
Method and apparatus for estimating surface moisture content of wood chips employing a surface moisture measurement obtained from a non-contact surface moisture sensor, which measurement is calibrated with values of a set of optical parameters, such as HSL color camera signals, representing light reflection characteristics of the wood chips in order to estimate the surface moisture content thereof.
