  • Patent number: 11586218
    Abstract: A method and apparatus for positioning a vehicle. The method may include: acquiring an identification element and non-identification elements of a current vehicle. The method can further include matching the identification element of the current vehicle with position elements in a high-precision map to determine an initial position of the current vehicle. The method can further include using at least one position element in the high-precision map to perform observational constraints on the non-identification elements of the current vehicle to acquire position elements corresponding to the non-identification elements of the current vehicle. The method can further include adjusting the initial position of the current vehicle using the position elements corresponding to the non-identification elements of the current vehicle to obtain a target position of the current vehicle.

  • Publication number: 20220364880
    Abstract: Embodiments of the present disclosure provide a map updating method and apparatus, a device, a server, and a storage medium, which relate to the field of artificial intelligence, and in particular, to the field of autonomous parking. The specific implementation solution is: an intelligent vehicle obtains driving data collected by a vehicle sensor of its own vehicle on a target road section, where the driving data at least includes first video data related to an environment of the target road section, and determines at least one image feature corresponding to each first image frame in the first video data, where the image feature at least includes an image local feature related to the environment of the target road section, and then updates map data corresponding to the target road section according to the at least one image feature corresponding to each first image frame in the first video data.

  • Publication number: 20220236065
    Abstract: The present disclosure provides a map data fusion method and apparatus, an electronic device, a medium and a program product. The method includes: acquiring first map data and second map data; based on a first feature descriptor set and a second feature descriptor set included in the first map data and the second map data respectively, determining a set of matching point pairs between a first set of three-dimensional coordinate points and a second set of three-dimensional coordinate points included in the first map data and the second map data respectively; determining a pose transformation matrix between the first map data and the second map data based on the set of matching point pairs; and fusing the first map data and the second map data into third map data based on the pose transformation matrix.
