  • Patent number: 10311618
    Abstract: A display assistance device detects the steering angle of a vehicle by using a steering angle sensor, and changes the position of a virtual viewpoint behind the host vehicle based on the detected steering angle. Then, the display assistance device converts images captured using a plurality of cameras such as a front camera and a rear camera into an overhead image of a downward view from the virtual viewpoint, and displays the converted overhead image on a display with a host vehicle icon superimposed on the overhead image, the host vehicle icon indicating the position of the vehicle.

  • Patent number: 10262215
    Abstract: A scene understanding device obtains map data where one, two or more obstacle detection frames, shaped corresponding to a road structure, for detecting an obstacle are set in advance for a specific spot on a road where a vehicle would otherwise bump into a vehicle or a pedestrian. The scene understanding device determines whether there exists an obstacle in the obstacle detection frames set for the specific spot on a scheduled traveling route of a host vehicle, and calculates the degree of risk at the specific spot based on a result of determining whether there exists an obstacle therein.

  • Patent number: 9649980
    Abstract: Captured images obtained beforehand by imaging ranges corresponding to peripheries of a vehicle, or processed images generated to correspond to the captured images are stored to be associated with stored road information of a preset area. A superimposed area having a clarity lower than a preset clarity threshold is set in a captured image of a periphery of the vehicle. A superimposition image is extracted among the stored images, the superimposition image being an image of a range corresponding to the captured image. A superimposed image is generated by superimposing an image in an area in the extracted superimposition image corresponding to the superimposed area on the captured mage. A video generated from the superimposed image is displayed at a position visible from a driver.
