Embodiments of the present disclosure disclose methods and devices for generating information. A specific embodiment of the method includes: obtaining a first point data set and a second point data set; respectively obtaining at least one first point data subset and at least one second point data set from the first point data set and the second point data set Data subset; determine at least one first bounding box corresponding to at least one traffic sign on the first collection trajectory and at least one second bounding box corresponding to at least one traffic sign on the second collection trajectory; based on at least one first The bounding box and at least one second bounding box determine a matching pair of bounding boxes, and generate a matching for characterizing the traffic signboard corresponding to the first bounding box in the bounding box matching pair and the traffic signboard corresponding to the second bounding box in the bounding box matching pair relationship information. In this embodiment, the matching relationship information of the traffic signboard on the first collection track and the second collection track is generated.
Description
technical field [0001] Embodiments of the present disclosure relate to the field of computer technologies, and in particular to methods and devices for generating information. Background technique [0002] Due to the limitations of the collection range and accuracy of collection equipment such as lidar, the same road often needs to be collected multiple times to fully cover its range. However, due to the limited accuracy of GPS (Global Positioning System, Global Positioning System) when collecting point cloud data, the point cloud data collected in different times may be layered. Therefore, it is necessary to fuse the point cloud data collected multiple times. The traditional point cloud data fusion is point-based fusion, which is to register and fuse multiple point cloud data by minimizing the distance between points. However, since the image frames collected at one time usually cover a range of tens of kilometers to tens of kilometers, the traditional point cloud data fu...
