| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we propose a method to estimate the ratio of window area in building wall from streetscape images on the web. In order to figure out the areas of mobile communications in advance, it is necessary to apply radio wave propagation simulation which requires 3D map data. However, it is generally very expensive to make the precise map data by field research. On the other hand, in recent years, streetscape images are published on the web. It is desirable to obtain accurate map data by analyzing these streetscape images. Among 3D map data, it is important to estimate the ratio of window area in building wall. This estimation poses a technical challenge because of the wide-baseline images and window refection. This paper proposes a novel approach which combines two methods to deal with the window refection; a method of merging multi-view streetscape images and a method of detecting the window areas on the upper building areas. |
