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: The present disclosure discloses a method and apparatus for acquiring information. A specific embodiment of the method includes: collecting characteristic information of a road object, the characteristic information comprising: a position, in a world coordinate system, of laser points corresponding to the road object in a laser point cloud collected in an area where the road object is located, and a position in a reflectance map corresponding to a position of a control point of the road object in the world coordinate system; and determining whether a preset accuracy is acceptable based on a match between the characteristic information of the road object and a preset characteristic information of the road object, the preset accuracy comprising: a splicing accuracy of the spliced laser point cloud, an accuracy of the reflectance map, and an accuracy of the high-precision map.
