Abstract

The invention discloses a processing method and device for guideboard information. The processing method comprises the steps that laser point data contained in laser point cloud data of a target road is clustered according to density to obtain at least one laser point data set; a periphery convex hull of the laser point data in the sets is acquired; and the guideboard information on the target road is recognized based on the shape and vertex angle of the periphery convex hull. Through the processing method and device, the technical problem that a guideboard detection method is low in precision is solved, and the guideboard information can be acquired accurately and efficiently.

Description

technical field [0001] The invention relates to the field of map data processing, in particular to a method and device for processing road sign information. Background technique [0002] In the current technology, the following two methods are generally used for street sign detection: [0003] The first is to detect street signs through road collection vehicles. This method first collects road videos through the road cameras installed on the road collection vehicles, and then plays back the collected road videos when making street sign data, and based on the road videos Determine the approximate location of road signs on the road, but the accuracy of this solution is too low to be helpful for autonomous driving. [0004] The second is to detect street signs through laser point clouds. This method first uses laser point clouds to process the street sign videos obtained by road acquisition vehicles to obtain laser point cloud data, and then uses artificial laser point cloud d...
