title Automatic Measurement System of Visible Greenery Ratio Using Augmented Reality
source Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 703-712
summary Greening has been promoted to improve the living condi- tions in urban environments. Quantification of greenery is an im- portant issue to identify the criteria for stakeholders in the process of greening. This research focuses on the quantification of visible green- ery ratio which is defined as the amount of greenery in the field of vi- sion. Some measurement methods of visible greenery ratio have been already proposed. However, the quantification process is usually time consuming and prone to human errors due to manual operations by us- ing an image processing software. Therefore, in this research, the au- thors developed an automated measurement system based on image processing technology for the efficient visible greenery ratio meas- urement. In the verification experiment, the proposed method achieved similar results for extracted pixels of green areas as the tradi- tional manual method, with decreased calculation time. Furthermore, in addition to measuring the current ratio of greenery, this system can visualize possible future changes in visible greenery by adding plant- ing (landscape) design models in an Augmented Reality (AR) envi- ronment. Using the proposed method, an ideal greening environment can be designed and evaluated by end-users, more intuitively. The de- veloped design system is expected to eventually result in increasing the amount of greenery in the urban environment.
