  • Publication number: 20210255326
    Abstract: An information processing device includes a server device, wherein a point cloud integrating section acquires point cloud data, and a deviation amount calculating section acquires aerial photograph data with a bird's view on a ground surface from sky. Then, the deviation amount calculating section calculates deviation amounts between absolute positions on the aerial photograph data and absolute positions for point clouds included in the point cloud data, wherein the absolute positions on the aerial photograph data and for point clouds correspond to predetermined reference points and. A trajectory correcting section corrects a travelling trajectory extracted from the point cloud data by a trajectory extracting section, based on the deviation amounts calculated in the deviation amount calculating section, wherein the absolute positions for point clouds in the point cloud data are corrected based on the correction result of the trajectory correcting section.

  • Publication number: 20210149052
    Abstract: The planimetric feature data stored in an external server has a data structure including recognized information about a recognizable range in which the planimetric features can be recognized by the sensors. Thereby, a control unit can determine whether or not a vehicle is located within the recognizable range. Based on this, it is possible to cause the sensors to perform sensing. Sensing leakage about a specific planimetric feature having such a planimetric feature data structure can be suppressed.

  • Publication number: 20210072392
    Abstract: An objective of the present invention is to provide a method for processing surrounding information which enables improvement of accuracy for estimation of a current position of a moving body. A current position of a moving body can be estimated with information after removal by acquiring surrounding information with a sensor in a surrounding information acquisition step, removing information of a feature including light transparent information from the surrounding information and thereby generating the information after removal. Here, the estimation accuracy can be improved by omitting the information about the light transparent region for which the acquired information may vary.

  • Publication number: 20210049375
    Abstract: A first onboard device-mounted on a measuring vehicle—includes a LiDAR, and it receives a reflected wave which is laser emitted to and reflected by a road surface and recognizes a curve start location of a lane line on the road surface based on reflected wave intensity. The first onboard device-transmits road surface information including the recognized curve start location to a server device via a network. The server device gives information indicating the curve start location to information regarding the lane line in map information based on the road surface information. A second onboard device mounted on a vehicle acquires the information regarding the lane line from the server device and estimates a current location by comparing a curve start location of the lane line recognized by a LiDAR and the information indicating the curve start location of the lane line acquired from the server device.

  • Publication number: 20210035448
    Abstract: An objective of the present invention is to provide a method for processing surrounding information which enables improvement of accuracy for estimation of a current position of a moving body. The objective is achieved by detecting light transparent region information of the surrounding information acquired by a sensor in a detection step, wherein the light transparent region information corresponds to a light transparent region. Further, in a generation step, information after removal is generated by removing the light transparent region information from the surrounding information. In this manner, a current position for a travelling vehicle can be estimated with the information after removal. The estimation accuracy can be improved by omitting the information about the light transparent region for which the acquired information may vary.

  • Patent number: 7822541
    Abstract: A map creation device includes a simple-ground-information creating unit, an on-ground-structure-information creating unit, and a map-information creating unit. The simple-ground-information creating unit creates, based on the ground object, a simple ground object expressing the three-dimensional shape with less amount of data than the ground object. The on-ground-structure-information creating unit creates, based on the simple ground object, an on-ground-structure object expressing a three-dimensional shape of an on-ground structure that is present on a surface of the ground by adding height information to a two-dimensional on-ground-structure object expressing a two-dimensional shape of the on-ground structure. The map-information creating unit creates map information in which the on-ground-structure object is superimposed on the ground object.

  • Publication number: 20090315881
    Abstract: In case it is necessary to have high-speed drawing processing such as display scrolling and so on, a drawing switching signal is input at a step, and high-speed drawing display data is output to a display at a step in response to this input, thereby display is performed. A high-speed drawing data generating means generates high-speed drawing display data for displaying each pixel concerning a character or visual object using a digitized gradation value digitized from each corresponding gradation value, and display is performed on this generated data. When it is necessary to have high-speed drawing, it is possible to have quick processing without increasing loads on a CPU and graphic controller on digitized data from gradation value.

  • Patent number: 7633500
    Abstract: A ground object is arranged so that it overlaps with a cylindrical object. Inside the cylindrical object, foot data of the ground object is arranged. Since the foot data on the side of a fore-end opening is positioned behind a fore-end face object with respect to view point coordinates, hidden surface removal is carried out for an image of the foot data on the side of the fore-end opening viewed from the view point coordinates by a Z value of a transparent drawn image of the fore-end face object.

  • Publication number: 20090174715
    Abstract: A font controller extracts and reads each time only the pre-rasterized bitmap font data groups to be used simultaneously among a plurality of pre-rasterized bitmap font data groups stored on the hard disk drive in advance, and expands and stores the groups in a work memory. With this arrangement, it is possible to significantly decrease the amount of memory consumed because the memory capacity required in the work memory is sufficient only with the read data amount to be extracted.

  • Publication number: 20080238914
    Abstract: A 3D road object is an object having road width, height, and length. The 3D road object corresponds to a link. A road surface texture is drawn repeatedly on the top surface of the 3D road object. With a map information creating device, geometry data in a cube shape containing a cross-section including the road width and the height can be extracted. Length of this geometry data can be set to the length of one sheet (one cycle) of the road surface texture in the length direction of the 3D road object. The road surface texture for one sheet as well as drawing cycle information can also be extracted. Moreover, link length information can be extracted from the link.

A three-dimensional-on-ground-structure-information creating unit (105) adds, using the simple-three-dimensional ground object created, height information to a two-dimensional on-ground-structure object indicating a two-dimensional shape of an on-ground structure present on a surface of the ground. Then, a three-dimensional on-ground-structure object indicating a three-dimensional shape of the on-ground structure is created. A three-dimensional-map-information creating unit (106) creates three-dimensional map information based on the three-dimensional ground object and the three-dimensional on-ground-structure object.
