Abstract

The invention relates to a smart traffic guideboard identification method and device. The method comprises the following steps: acquiring at least two images, wherein each image comprises at least one common guideboard; performing guideboard corner detection on at least one common guideboard in each image by using a preset high-resolution neural network model, and identifying a pixel coordinate position of each guideboard corner corresponding to at least one guideboard in each image; and generating the geographic coordinate position of each guideboard according to the pixel coordinate positions of the guideboard angular points corresponding to each guideboard in the at least two images and the geographic position information of a camera when the at least two images are shot. According to the scheme provided by the invention, the guideboard can be automatically generated, rapid generation of at least one guideboard is realized, and the drawing efficiency of the high-precision map is improved.

Description

technical field [0001] The present application relates to the field of navigation technology, in particular to a method and device for identifying intelligent traffic signs. Background technique [0002] With the development of technologies such as artificial intelligence and autonomous driving, the construction of intelligent transportation has become a research hotspot, and high-precision maps are an indispensable part of the construction of intelligent transportation data. High-precision maps can contain a variety of traffic signs. For example, detailed lane maps can be used to express ground features such as lane lines, stop lines, and pedestrian crossing lines in the real world, as well as high-altitude feature elements such as street signs and traffic lights, so as to support automatic driving. Provide data support for navigation in other application scenarios. [0003] As the information carrier of urban geographical entities, road signs in traffic signs have informa...
