Title:
SYSTEM, APPARATUS, METHOD, AND PROGRAM FOR MEASUREMENT OF LEAF AREA INDEX
Document Type and Number:
WIPO Patent Application WO/2012/073519
Kind Code:
A1
Abstract:
Provided is a leaf area index measurement system provided with: a reflector arranged in the vicinity of a plant to be subjected to measurement; an image capturing means that is arranged at a position where no shielding object exists between the image capturing means and the reflector, and that is for capturing an image of the reflector and outputting the captured image; an intensity calculating means for calculating the intensity of light reflected by the reflector, on the basis of the captured image outputted by the image capturing means; and a leaf area index calculating means for calculating a leaf area index on the basis of the intensity of light calculated by the intensity calculating means.
