Embodiments of the disclosure provide systems and methods for positioning a vehicle. The system includes a communication interface configured to receive point cloud frames with respect to a scene and initial pose data of a vehicle captured by sensors equipped on the vehicle as the vehicle moves along a trajectory. The system also includes a storage configured to store the point cloud frames and the initial pose data. The system further includes a processor configured to estimate pose information of the vehicle associated with each of the point cloud frames based on the initial pose data and the point cloud frames. The processor is also configured to adjust the estimated pose information of the vehicle based on a model. The model includes a spatial relationship and a temporal relationship among the plurality of point cloud frames. The processor is further configured to position the vehicle based on the adjusted pose information.

Embodiments of the disclosure provide systems and methods for updating an HD map. The system may include a communication interface configured to receive sensor data acquired of a target region by at least one sensor equipped on a vehicle as the vehicle travels along a trajectory via a network. The system may further include a storage configured to store the HD map. The system may also include at least one processor. The at least one processor may be configured to identify a plurality of data frames associated with a landmark, each data frame corresponding to one of a plurality of local HD map on the trajectory. The at least one processor may be further configured to jointly optimize pose information of the plurality of local HD maps and pose information of the landmark. The at least one processor may be further configured to construct the HD map based on the based on the pose information of the plurality of local HD maps.

Systems and methods for constructing a high-definition map based on landmarks

Embodiments of the disclosure provide systems and methods for updating a high-resolution map. The system may include a communication interface configured to receive a plurality of image frames captured by a binocular camera equipped on a vehicle, as the vehicle travels along a trajectory. The system may further include a storage configured to store the high-resolution map and the plurality of image frames. The system may also include at least one processor. The at least one processor may be configured to generate point cloud frames based on the respective image frames. The at least one processor may be further configured to position the vehicle using the point cloud frames. The at least one processor may be further configured to merge the point cloud frames based on the vehicle positions. The at least one processor may also be configured to update a portion of the high-resolution map based on the merged point cloud.

A display method, apparatus, and program product for a bendable electronic device. The method determines whether a display of a bendable electronic device is in a planar first form or in a curved second form. The method displays a first interface of a first application in response to determining that the display is in the planer first form. The method displays a second interface that is available in the first application, the second interface adaptive to the curve second form, in response to determining that the display is in the curved second form is disclosed. An apparatus and/or a program product may perform the method.
