야간경관조명의 조명방식에 따른 평가특성 분석

The purpose of this paper is to analyse evaluation characteristics according to a lighting method of exterior lighting. In this paper, we verified effectiveness of CG as an evaluation tool after we primarily extracted evaluation vocabulary via previous experiment. And then, we conducted subjective evaluation experiment after producing an evaluation object by CG according to a lighting method of exterior lighting. Finally, we analysed the factor of an evaluation result, analysing according to a lighting method of exterior lighting. The result of this paper is as follows: 1) The physical quantity presented by CG, compared with the real thing, is that the total relative error rate was within 5%. Also it did not have a quite difference in subjective evaluation experiment with the real thing in the most items excluding a part of evaluation items of subjective evaluation experiment by CG. 2) The 3 image axises of「exuberant」,「stable」and「warm」were selected as the result of the factor analysis In order to make sure the evaluation structure of exterior lighting. 「exuberant」and「stable」images were influenced a lot by a lighting method, and 「warm」image was affected by light color. The evaluation on the line lighting, the dot lighting and the compound lighting in「exuberant」image was high, and in「stable」image, the up and down lighting, the「transmitted lighting」, and the compound light were high. In「warm」image, the light color of yellow color as a warm color type was evaluated high, and the light color of green color as a cold color type was evaluated high in「mysterious」item.
