Research of technology for recognizing photography management items from image data of construction fields

In recent years, the electronic delivery of various deliverables has been implemented in the construction field through the promotion efforts of the Ministry of Land, Infrastructure, Transport and Tourism. One of these deliverables is the image data of photograph taken at construction site. For the electronic delivery of this data, the photography management items showing the contents photographed in the image data of construction site must be submitted along with the image data of construction site itself. Therefore, in this research, we develop a system for automatically acquiring contents for registering the photography management items from the image data of construction site.
