Abstract

The application discloses a method and device for generating road traffic markings in a high-precision map. The method includes the following steps of: acquiring point cloud data and image data including the road traffic markings, wherein the point cloud data and the image data have a corresponding relationship; generating a color laser base map according to the point cloud data and the image data; identifying the road traffic markings from the color laser base map according to the reflectance value, color information and a preset road traffic marking identification model; and generating roadtraffic marking elements in the high-precision map based on the identified road traffic markings. The scheme of the invention has the beneficial effects that the image data and the point cloud data are combined, the color laser base map is generated, and then the road traffic markings are automatically extracted and drawn based on the road traffic marking identification model, so that the cost ofdata post-processing can be greatly reduced, the working efficiency and accuracy can be improved, the effects of the light and environment can be reduced, the stability of result output can be ensured, and thus the scheme of the invention can be used to build the high-precision map.

Description

technical field [0001] The present application relates to the technical field of high-precision maps, in particular to a method and device for generating road traffic markings in high-precision maps. Background technique [0002] High-precision maps, also referred to as high-precision maps, are one of the core technologies relied on in areas such as autonomous driving. The traditional method is to use certain tools for manual drawing. There are also some technologies that use the corresponding projection relationship between point cloud data and image data to adopt a partial automatic labeling process, and finally optimize it by manual labeling. However, for the object of road traffic markings, because it is difficult to identify it in the usual way, it is often drawn manually in the prior art, which cannot make good use of the collected image data and point cloud data. , the efficiency and accuracy are also low. Contents of the invention [0003] In view of the above pr...
