SUNSHINE EVALUATION SYSTEM, AND COMPUTER PROGRAM FOR SUNSHINE EVALUATION

摘要

PROBLEM TO BE SOLVED: To provide a technology capable of evaluating a reflection direction of sunlight reflected on an installation object installed at an imaging point of a sky image in addition to a sunshine state, in a sunshine evaluation system.;SOLUTION: A sunshine evaluation system receives input of a sky fisheye image G1, converts the image G1 in a panoramic manner to generate a sky panoramic image G2, and displays the image G2 on a display screen 2; automatically determines a non-sunshine area A2 and a sunshine area A1 in the image G2; and displays an orbit of a sun direction P1 overlapped with the image G2 on the display screen 2, in a state where an attribute as to whether or not the sun direction P1 is a sunlight direct direction P1a can be recognized. The sunshine evaluation system receives input of an imaging point, derives an orbit of a reflection direction P2a from an attitude state of an installation object installed at the imaging point and the sunlight direct direction P1a, and displays the orbit of the reflection direction P2a overlapped with the image G2 on the display screen 2; and displays the orbit of the reflection direction on the display screen 2 in a state where a reflection attribute as to whether or not the orbit of the reflection direction overlaps with the non-sunshine area A2 can be recognized.;COPYRIGHT: (C)2014,JPO&INPIT
