  • Publication number: 20200193174
    Abstract: A section line recognition device is realized which can determine a line type of a section line in a road surface with high accuracy. In step 301, a feature amount is extracted from an image captured by each camera. This step corresponds to a process of a feature point extraction unit. In the next step 302, the extracted feature amount is transformed into bird's-eye view coordinates which is common coordinates. This step corresponds to a process of a coordinates transformation unit. Next, in step 303, a camera to be selected is determined. This step is a process of a camera determination unit. Next, in step 304, the state transition at the appearance position of the feature point on the bird's-eye view coordinates is determined using feature point coordinates of the camera selected in step 303. This step is a process of a state transition determination unit. Finally, in step 305, the line type is determined. This step is a process of a line type determination unit.

  • Patent number: 8290699
    Abstract: A method for geographic interpolation of traffic data in a vehicle navigation system in which the navigation system includes a map database divided into geographic meshes. Each mesh includes a plurality of road links of different types. That data also includes a first set of meshes containing traffic flow data while a mutually exclusive second set of meshes contains no such traffic flow data. A border between the first and second set of meshes is first identified and thereafter a blend zone of blend meshes is created by selecting at least one mesh adjacent the border so that the blend mesh is interposed between the first and second set of meshes. Thereafter, the traffic data for each type of road link in the blend mesh is adjusted to a value intermediate the first and second set of adjacent meshes for each type of road link and the blend mesh data is then stored.

  • Patent number: 8068973
    Abstract: A traffic information providing system externally acquires traffic information including information relating to the travel time of a link, calculates a travel time for a non-provision link to which no travel time is provided through estimate/complement operation. The estimate/complement operation is carried out with use of travel times, emergencies, travel times of links in the vicinity of the non-provision link, and so on, obtained in the near past. The system stores and statistically processes the externally-acquired traffic information, and also estimates a travel time in the near future. When there is an abnormality in the acquired traffic information, the system deletes the abnormality, regards the information as a non-provision link, calculates a probability distribution of travel times of links, calculates a probability distribution of travel times of the entire route made up of a plurality of links, and also calculates a probability for a specific travel time range.

  • Patent number: 7957559
    Abstract: In conventional systems using an onboard camera disposed rearward of a vehicle for recognizing an object surrounding the vehicle, the object is recognized by the camera disposed rearward of the vehicle. In the image recognized by the camera, a road surface marking taken by the camera appears at a lower end of a screen of the image, which makes it difficult to predict a specific position in the screen from which the road surface marking appears. Further, an angle of depression of the camera is large, and it is a short period of time to acquire the object. Therefore, it is difficult to improve a recognition rate and to reduce false recognition. Results of recognition (type, position, angle, recognition time) made by a camera disposed forward of the vehicle, are used to predict a specific timing and a specific position of a field of view of a camera disposed rearward of the vehicle, at which the object appears.

  • Patent number: 7912635
    Abstract: The present invention aims to provide a technique that can download traffic information in a more efficient manner, in a navigation system including a traffic information distribution server and a terminal unit. The information distribution server narrows down possible traffic information to be used for processing at the terminal unit before downloading the information to the unit. For example, the traffic information distribution server may include a traffic information obtaining unit for obtaining traffic information pertaining to a link configuring a route or the periphery of the link (e.g., mesh area including the link), and to a predicted running duration of the link; and a sending unit for downloading the obtained traffic information to the terminal unit. The server or the terminal unit may narrow down the object for download.

  • Publication number: 20100332121
    Abstract: A server device 1 included in the route-search system 7 comprises a guided-navigation-route-search section 130 for searching a route starting from a departure point and reaching a destination; and a preparatory-route-search section 140 for searching a preparatory route in view of a possible deviation of the vehicle from a navigation route. The server device 1 transmits information on the navigation route and the preparatory route to the navigation device 2. When detecting the deviation of the vehicle, the navigation device 2 selects one of preparatory routes having nodes closest to the current position of the vehicle. The navigation device 2 searches a supplementary route connecting the current position of the vehicle to the nodes, and combines the preparatory route with the supplementary route to create a new route for continuing navigating the vehicle to the destination.

  • Patent number: 7782179
    Abstract: An obstacle detection apparatus more accurately detects a moving obstacle present around a motor vehicle. With this system, desired feature quantities of an obstacle present in a coverage of a first sensor are calculated and then stored into a storage device, and when the obstacle moves from the coverage of the first sensor to a coverage of a second sensor, a relative distance to the obstacle is calculated from the above-stored feature quantities of the obstacle and from the desired feature quantities of the obstacle, obtained by analyzing the recognition results of the second sensor that have been processed by a processor which processes the recognition results.
