Patent number: 8665263Abstract: An apparatus and method generating a road image including no features such as trees and tunnels hiding or covering a road surface. A mobile measuring apparatus installed in a vehicle may acquire a distance and orientation point cloud, a camera image, GPS observation information, a gyro measurement value, and an odometer measurement value, while moving in a target area. The position and attitude localizing apparatus may localize the position and attitude of the vehicle based on the GPS observation information, the gyro measurement value and the odometer measurement value. The point cloud generating apparatus may generate a point cloud based on the camera image, the distance and orientation point cloud, and a position and attitude localized value.Type: GrantFiled: August 24, 2009Date of Patent: March 4, 2014Assignee: Mitsubishi Electric CorporationInventors: Mitsunobu Yoshida, Masakazu Miya, Yoshihiro Shima, Junichi Takiguchi, Ryujiro Kurosaki

Patent number: 8625851Abstract: 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: GrantFiled: July 12, 2012Date of Patent: January 7, 2014Assignees: Mitsubishi Electric Corporation, Waseda UniversityInventors: Junichi Takiguchi, Naoyuki Kajiwara, Yoshihiro Shima, Ryujiro Kurosaki, Takumi Hashizume

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. A model projecting unit 172 projects a point cloud on the image, and an image displaying unit 341 displays the point cloud superimposed with the image on the displaying device.

Publication number: 20110310091Abstract: An objective is to provide a road image including no features such as trees and tunnels hiding or covering a road surface. A mobile measuring apparatus 200 installed in a vehicle may acquire a distance and orientation point cloud 291, a camera image 292, GPS observation information 293, a gyro measurement value 294, and an odometer measurement value 295, while moving in a target area. The position and attitude localizing apparatus 300 may localize the position and attitude of the vehicle based on the GPS observation information 293, the gyro measurement value 294 and the odometer measurement value 295. The point cloud generating apparatus 400 may generate a point cloud 491 based on the camera image 292, the distance and orientation point cloud 291, and a position and attitude localized value 391.Type: ApplicationFiled: August 24, 2009Publication date: December 22, 2011Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Mitsunobu YOSHIDA, Masakazu MIYA, Yoshihiro SHIMA, Junichi TAKIGUCHI, Ryujiro KUROSAKI
