Abstract

The invention discloses a drawing method and device, electronic equipment and a readable storage medium, and relates to the field of automatic driving. According to the specific implementation scheme,multiple frames of point clouds in a place where a vehicle is located are collected, and the multiple frames of point clouds are spliced based on the target pose transformation information to obtaina map of the place where the vehicle is located. The target pose transformation information comprises relative pose transformation information of the point clouds and sub-graphs where the point cloudsare located, relative pose transformation information between the adjacent point clouds, relative pose transformation information between the sub-graphs and a transformation relation between a localcoordinate system and a global coordinate system. According to the method, the problem that the drawing efficiency is not high due to the fact that the uploading time of the data to a server is too long is avoided, and meanwhile the flexibility of drawing is greatly improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a drawing method, device, electronic equipment and readable storage medium, which can be used for automatic driving and intelligent transportation. Background technique [0002] During the driving process, the self-driving car needs to automatically sense and detect the road environment, and make decisions to control the movement of the vehicle. If there is a slight deviation, it will affect the safety of the self-driving car. The high-precision map contains a large amount of detailed information on the road environment, including intersection layout, road sign location, traffic light information, and road speed limit information. The accuracy can reach the centimeter level, so it can effectively guarantee the driving safety of autonomous vehicles. Therefore, how to produce high-precision maps has become a research hotspot. [0003] In the exist...
