Abstract

The present application relates to a correction method and a related device for a guide arrow map mark. The method includes: acquiring two adjacent lane lines and a guiding arrow located between the two lane lines; generating a rectangular bounding box surrounding the guiding arrow according to the position of the guiding arrow; selecting the The frame edges of the two forward directions are used as two pointing lines; according to the two pointing lines, two judgment lines are correspondingly generated on the two lane lines; according to the two judgment lines and the pointing lines , adjust the position of the bounding box; modify the guide arrow according to the adjusted position of the bounding box. The solution provided by the present application can adjust the direction of the guide arrow to ensure the correctness of the direction of the guide arrow.

Description

technical field [0001] The present application relates to the technical field of navigation, in particular to a correction method and a related device for a guide arrow map mark. Background technique [0002] The guide arrow map sign is usually located between two lane lines. The guide arrow map sign is used to convey traffic management information and play a guiding role for driving. The production of high-precision maps needs to generate lane lines and guiding arrows, so as to provide a basis for the automatic driving of vehicles. [0003] However, in real life, there are often unreasonable problems in the orientation of the guide arrow map signs on the road, such as the tilt and offset of the guide arrow map signs, which affects the correctness of the production of high-precision maps. Contents of the invention [0004] In order to solve or partially solve the problems existing in the related technology, the present application provides a correction method and related ...
