Title:
FISHEYE IMAGE DATA CREATION PROGRAM AND LAI COMPUTATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/122800
Kind Code:
A1
Abstract:
The fisheye image data creation program according to one aspect of the present invention causes a computer to execute a step for reading-in three-dimensional forest point group data, a step for creating three-dimensional reference point data, a step for calculating at least any two amplitude data of forest point data constituting the forest point group data using the reference point data as a reference, a step for creating two-dimensional fisheye image data on the basis of the two amplitude data of the forest point data, and a step for calculating an LAI on the basis of the fisheye image data.
