Construction of Three-dimensional Data of Road Based on Video Images

Abstract

It is necessary to construct three-dimensional data for realizing three-dimensional maintenance of the road. Three-dimensional data of road space are often constructed using Mobile Mapping System and terrestrial laser scanner. When acquiring three-dimensional point cloud data with a laser scanner, the laser hits the feature in front, data cannot be acquired for the features behind the sidewalk, etc. It is necessary to measure it several times. On the other hand, as one of the methods for constructing three-dimensional data, there is the SfM (Structure from Motion) technique. In this research, a method to generate three-dimensional data of road space based on SfM technique from video data taken with a commercially available video camera was studied for road maintenance.
