Abstract

The invention discloses a method and related equipment for collecting lane changing data of a main vehicle in a congestion scene, and the method comprises the steps: obtaining the automatic driving data of the main vehicle, wherein the automatic driving data comprises the data under each theme; dividing the automatic driving data from a time dimension to obtain each data frame with time as an index, the data frames comprising data under each theme in the time; in combination with semantic map data, screening out target data frames of lane changing of the main vehicle in the congestion scene from all the data frames; and aggregating the target data frames according to a preset condition to obtain lane changing data in the congestion scene. According to the method and the device, the lane changing data of the main vehicle in the congestion scene can be collected, and related data support is provided for development of an automatic driving technology.

Description

technical field [0001] The present application relates to the field of unmanned driving technology, and more specifically, relates to a method for collecting lane-changing data of a main vehicle in a congestion scene and related equipment. Background technique [0002] Whether the automatic driving system can handle complex scenes well can directly reflect the quality of automatic driving technology. Among them, the main vehicle changing lanes in a congested scene is a relatively common and difficult to handle scene in automatic driving. [0003] When the main vehicle changes lanes in a congested scene, if the algorithm is not handled properly, collisions and even dangerous accidents will easily occur. If you have a large amount of data of the main vehicle changing lanes in a congested scene, you can conduct a simulation test on the autonomous driving algorithm, and you can find problems as early as possible in the algorithm development stage, and you can better evaluate th...
