Embodiment Construction

[0086] The embodiments of the present invention provide a method, device, equipment and storage medium for collecting a lane change scene. The method calculates the obstacle between the off-site information and the host vehicle by calculating the off-site information in each data frame in the drive test data set. Based on the obstacle relationship, the scene type is determined, and the data frames in the drive test data set are classified according to the scene type to obtain the lane change scene data set. In the case of a large amount of road test data, it is possible to quickly identify the lane change scene, and filter out the corresponding lane change scene data, and it is based on the calculation of the obstacle relationship between vehicles. In this way, the vehicle is used as the unit. The recognition can greatly improve the accuracy of scene recognition.

Abstract

The invention relates to the field of automatic driving testing, and discloses a lane changing scene acquisition method, device and equipment and a storage medium, and the method comprises the steps: calculating an obstacle relationship between off-site information and a main vehicle through the off-site information in each data frame in a road test data set, and determining a scene type based on the obstacle relationship; and classifying the data frames in the drive test data set according to the scene type to obtain a lane changing scene data set. By identifying the obstacle relationship between the vehicles in the data frame, the scene identification accuracy is greatly improved by taking the vehicle as a unit, so that various lane changing scenes are accurately, efficiently and automatically acquired from the road test data set, the data processing efficiency is remarkably improved, and the user experience is improved. And the development process efficiency of the automatic driving algorithm of the subsequent lane changing scene is improved.

Description

technical field [0001] The invention relates to the field of automatic driving testing, and in particular, to a method, device, equipment and storage medium for collecting a lane change scene. Background technique [0002] With the development of intelligent control technology, especially in the automotive field, autonomous driving has become a development trend, and autonomous driving testing is an indispensable link in the development of autonomous driving. To achieve the improvement and optimization of autonomous driving technology, The test scenarios and the collection of test data under each scenario are the top priority. At present, the collection of test scenarios and test data in each scenario is mainly to first collect the complete test data, then manually divide the completed test data according to the scenarios, and then select part of the test data of the required scenarios. The efficiency of the method is too low to meet the needs of research and development, e...
