  • Patent number: 8665263
    Abstract: 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.

  • Patent number: 8625851
    Abstract: 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.

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: 20110310091
    Abstract: 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.

  • Patent number: 6058339
    Abstract: When material transport was automated on a building construction site, in a conventional travel tape guide system, it was necessary to replace the tape when it became soiled or when changes were made to a travel route. As a result, the usage efficiency of a material transport vehicle could not be improved on the site due to the fact that changes are made to work floors as demanded by construction schedules. According to this invention, there is provided a sign which is easy to move and which is installed at a turning point or an unloading point on a work floor transport route. An image of the sign is obtained by an imaging device on an autonomous guided vehicle and operating instructions are recognized by image processing. This makes it possible to automate the setting of routes and the control of the vehicle.
