选取上海市黄浦江徐汇滨江段的10个样方作为研究样本,根据文献研究建立基于生态-活力目标的夜景照明评估标准,采用适宜性评价方法量化评价各样方夜景照明照度在生态目标和活力目标两方面的达成情况,并据此通过帕累托前沿法对10个样方进... 选取上海市黄浦江徐汇滨江段的10个样方作为研究样本,根据文献研究建立基于生态-活力目标的夜景照明评估标准,采用适宜性评价方法量化评价各样方夜景照明照度在生态目标和活力目标两方面的达成情况,并据此通过帕累托前沿法对10个样方进行分析,结果表明,尽管不同的使用主体和活动的照度需求在数值上存在权衡关系,但可以通过合理的照度空间布局进行缓解。建议在滨水空间照明设计时,依据功能分区的需求识别进行照明布局,考虑运动活动区高照度需求影响,综合评估灯具特性针对性布设。 展开更多

Then a computer-aided evaluating method is put forward. In this process two groups are needed. The control group is made up of people who wear maillot while the experimental group consists of those who wear target clothes to be evaluated. People in these two groups are taken photos respectively from front, back and lateral sides. The photos are input computer and receive a series of image processing using Open CV which provides the open source library function including image preprocessing, edge detection and image segmentation, etc. Finally, taking the clothing ease into account, the processed data is used for region matching and evaluating the grade of clothing fit. 展开更多
