  • Publication number: 20240107169
    Abstract: A method computes a final image of an area surrounding a vehicle, from at least one image captured in a first angular portion of the area surrounding the vehicle by a camera and a distance between the vehicle and a point in the surrounding area, which distance is determined, in a second angular portion located in one of the first angular portions, by at least one measurement sensor. The method includes capturing an image and, for each captured image, correcting a distortion in the captured image to generate a corrected image; for each corrected image, transforming the perspective of the corrected image using a matrix storing a pre-calculated distance between the camera and a point in the corresponding surrounding area; and adding the transformed images to obtain the final image. The perspective transforming includes adjusting the pre-calculated distance to the distance determined by the measurement sensor.

  • Patent number: 11928619
    Abstract: A vehicle dispatch service boarding location determination method uses a vehicle dispatch information data server and a terminal to determine a boarding location for a dispatched vehicle based on a vehicle dispatch request from the terminal. When there is a vehicle dispatch request, position information of a vehicle dispatch request point is acquired. Boarding location candidates present in a periphery of the vehicle dispatch request point are calculated based on the position information point and map information. A boarding location recognition difficulty, which is a difficulty for the user in recognizing the boarding location candidate as a boarding location, is calculated for each of the boarding location candidates. A boarding location candidate for which the boarding location recognition difficulty is low among the boarding location candidates is determined as the boarding location where the user will be picked up by the dispatched vehicle.
