Publication number: 20130011013Abstract: It is an object to measure a position of a feature around a road. An image memory unit stores images in which neighborhood of the road is captured. Further, a three-dimensional point cloud model memory unit 709 stores a point cloud showing three-dimensional coordinates obtained by laser measurement which is carried out simultaneously to the image-capturing of the images as a road surface shape model. Using an image point inputting unit 342, a pixel on a feature of a measurement target is specified by a user as a measurement image point. A neighborhood extracting unit 171 extracts a point which is located adjacent to the measurement image point and superimposed on the feature for the measurement target from the point cloud. A feature position calculating unit 174 outputs three-dimensional coordinates shown by the extracted point as three-dimensional coordinates of the feature for the measurement target.Type: ApplicationFiled: July 12, 2012Publication date: January 10, 2013Applicants: Waseda University, MITSUBISHI ELECTRIC CORPORATIONInventors: Junichi TAKIGUCHI, Naoyuki Kajiwara, Yoshihiro Shima, Ryujiro Kurosaki, Takumi Hashizume
