Abstract

The embodiment of the invention provides a method and a device for automatically extracting arrow marked lines in high-precision map manufacturing. The method comprises: using three-dimensional pointcloud data as input, automatically extracting arrow target shape points from end to end, effectively extract the arrow target shape points by using an image key point regression method, and ensure that the arrow extraction precision meets the high-precision map manufacturing requirement; using point cloud semantic segmentation to obtain high-level semantic relation scene understanding, and improving algorithm robustness. The accuracy of arrow type marking line extraction and the automatic manufacturing efficiency of a high-precision map can be effectively improved, and the workload of manual marking is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of high-precision map production, and more specifically, to a method and device for automatically extracting arrow markings in high-precision map production. Background technique [0002] The invention of the automobile has changed the way of human travel. It strongly promotes the flow of goods and people with its convenience and speed, and plays an important role in the development of economy and society. With the continuous development of production technology, new production methods have reduced the unit production time of automobiles, lowered the unit price of automobiles, and made automobiles a mass product. As of 2010, there are about 1 billion vehicles of various types in the world, and this number is still growing at a high speed. However, with the increase of car ownership, the problem of traffic safety has become more and more prominent. In China, there are more than 500,000...
