Abstract: Provided are a method for constructing a three-dimensional map in a high-definition map, a device and a storage medium. The method includes: acquiring vehicle trajectory data, where the vehicle trajectory data is three-dimensional trajectory data; matching the vehicle trajectory data with a lane in a two-dimensional map and determining vehicle trajectory data matched with the lane; and assigning a height to the lane in the two-dimensional map according to the matched vehicle trajectory data to obtain a three-dimensional map.

Abstract: Disclosed embodiments include a method and a device for generating position information of a target object. In some embodiments, the method comprises: obtaining target point cloud data of the target object, acquired by a target scanner at a target position, and position information of the target scanner, and obtaining reference point cloud data of the target object, acquired by a reference scanner at a reference position, and position information and an Euler angle of the reference scanner; obtaining an Euler angle of the target scanner based on the target point cloud data, the reference point cloud data, and the Euler angle of the reference scanner; and generating the position information of the target object based on the target point cloud data, the position information and the Euler angle of the target scanner, the reference point cloud data, and the position information and the Euler angle of the reference scanner.

Abstract: Embodiments of the present application provide a method and device for generating digital verification codes. The specific implementation of the method comprises the following steps: selecting a first number of different digitals from digitals 0-9 when it is needed to generate a digital verification code, wherein the first number is smaller than the number of digits of the digital verification code to be generated; generating a digital verification code including at least two identical digitals appeared consecutively by arranging and combining the first number of different digitals according to a preset rule; and outputting the generated digital verification code to a designated user terminal. By applying the embodiments of the present application, it is possible to reduce the difficulty for a user to remember the digital verification codes.
