5 results about "Map labeling" patented technology

This application relates to a method, apparatus, electronic device, and mobile tool for annotating a grid map. The method includes: acquiring an occupied grid map and a reflectance grid map of a target area, wherein the reflectance grid map records the reflectance of point cloud data of the ground in the target area; mapping the reflectance of laser point clouds with reflectance less than a preset value in the reflectance grid map to a first interval, and mapping the reflectance of laser point clouds with reflectance greater than or equal to the preset value to the maximum value of the first interval, where the maximum value of the first interval is greater than the preset value; and annotating map features in the target area based on the occupied grid map and the adjusted reflectance grid map. This application solves the technical problem that the occupied grid map annotation is inaccurate and cannot reflect the obstacle situation within the area.

The application discloses a Beidou-based internet map digital intelligent labeling method and system, and belongs to the technical field of map labeling. The method specifically comprises the following steps: positioning and timing a mobile terminal by using a Beidou satellite navigation, generating trusted labeling data containing position information and a time stamp, collecting multi-modal sensing data by the mobile terminal, identifying and extracting labeling objects related to a map, and binding the labeling objects with the trusted labeling data to obtain a labeling object set, performing space-time normalization processing on the labeling object set, and converting the labeling object set into standardized labeling information available for an internet map service, aggregating and resolving conflicts of the standardized labeling information, and generating a trusted labeling result. The application improves the high precision and verifiability of labeling data, and also realizes cross-platform standardized intercommunication and real-time dynamic updating.

The application provides a trajectory prediction method and device, electronic equipment and storage medium. The method comprises the following steps: obtaining a model prediction trajectory of a risk obstacle target located within a preset distance range of a vehicle; obtaining a first intention corresponding to the model prediction trajectory; generating a rule prediction trajectory and a second intention of the risk obstacle target based on information of the risk obstacle target and a preset rule; and determining a final prediction trajectory of the risk obstacle target from the model prediction trajectory and the rule prediction trajectory based on the first intention and the second intention. The generation of the rule prediction trajectory and the model prediction trajectory is two independent steps, the intentions are not confused, the two trajectories only have a replacement relationship and no fusion relationship, the rule does not directly modify the model prediction trajectory, and controllability is strong. In addition, the scene does not need to be recognized, the map does not need to be labeled, and the specialized model does not need to be used, so that the development, training and deployment costs are not consumed, and only the deep learning model needs to be continuously iterated to improve the upper limit of the model.
