Abstract
A method and an apparatus for 4D road scene annotation based on time series data includes: obtaining point cloud data and multi-view 2D image data of a same road scene at a same time series, as well as a rotation matrix R and a translation vector t obtained through sensors; merging all the point cloud data into a combined point cloud using the rotation matrix R and the translation vector t; performing dynamic and static object annotation and lane line annotation on the combined point cloud in the 4D road scene; and mapping annotation information in the 4D road scene to all the 2D image data at the time series based on camera parameter information, to obtain annotation information on 2D images. The method fully utilizes time series information, avoiding the loss of important information.
