  • Patent number: 11761788
    Abstract: A method and an apparatus for generating an offline map are disclosed. The method includes: obtaining 1st to nth environmental images sequentially collected by a camera of a vehicle when the vehicle is traveling on a target road section; selecting ith to jth environmental images from the 1st to Nth environmental images, performing a first batch of three-dimensional modeling on the ith to jth environmental images to obtain first posture information of the camera and a first world coordinate; performing a second batch of three-dimensional modeling in parallel on the 1st to (i?1)th environmental images and (j+1)th to Nth environmental images, based on the first posture information and the first world coordinate, to obtain a second world coordinate and to obtain a third world coordinate; and generating an offline map of the target road section according to the world coordinate.

  • Patent number: 11619498
    Abstract: The present application discloses a verification method and device for a modeling route, an unmanned vehicle, and a storage medium, which relate to the technical field of computer vision and intelligent transportation. A specific implementation of the method in the present application lies in: acquiring a filtering threshold of a target road section, where the filtering threshold is related to image feature points corresponding to the target road section; verifying a modeling route corresponding to the target road section through the filtering threshold to obtain a verification result. According to the present application, availability of the modeling route can be directly verified with the filtering threshold while there is no need to verify the modeling route through manual driving of the vehicle, thereby effectively increasing the verification efficiency, protecting the vehicle from travelling along an unavailable modeling route and improving the driving experience.

  • Patent number: 11017270
    Abstract: A method and an apparatus for image processing for a vehicle are provided. The method includes: acquiring an image presenting a target object; occluding at least one area of the image to obtain at least one occluded image; inputting the at least one occluded image into a pre-trained image processing model to obtain a driving parameter corresponding to each of the at least one occluded image; determining, for each driving parameter, a difference between the driving parameter and a real driving parameter corresponding to the acquired image; and determining whether the difference between the driving parameter of the occluded image occluding at least one area where the target object is located and the real driving parameter is greater than or equal to a difference threshold, to determine a degree of association between the state of the target object and the driving parameter.
