AN IMAGE PROCESSING BASED METHOD TO ESTIMATE CROP REQUIREMENTS FOR NUTRIENT FERTILISER

摘要

A method and device for analysing a leaf to provide data on leaf content and/or dimensions of said leaf. The device (100) comprises an optical scanner having a power source (1) power/scan button (2) and a scanning aperture (10). The device is adapted to pass over the leaf and capture an image of at least a part of the leaf. A suitable processor then processes the resultant image from the optical scanner (100) to produce data on leaf content and/or leaf dimensions. In one embodiment processor may apply a plurality of algorithms to provide data on leaf dimension, nutrient content and/or chlorophyll status of the leaf.
