Problems solved by technology

[0003] At present, most of the annotation data is manually annotated, including 2D images, 3D lidar point cloud data, etc., which is a very slow and inefficient process
It requires people to sit in front of a computer screen to operate annotation tools and mark them one by one, which is extremely labor-intensive
For lidar data, due to the complexity and sparseness of its data form, it is easy to label errors or miss labels, and may even have a negative impact on neural network training

Abstract

The embodiment of the invention discloses a system, method and device for labeling continuous frame data. The system comprises a cloud end and a labeling end, wherein the cloud end reads continuous frame data, and performs target detection on each frame of data in the continuous frame data according to a labeling task to obtain a detection result of a to-be-labeled object in each frame of data; according to the detection result and the time sequence information of each frame of data, an association relationship between the same object to be labeled in each frame of data is established as a pre-labeling result; an extensible pre-labeling file is generated according to the pre-labeling result, and the pre-labeling file and the continuous frame data are sent to the labeling end; and the labeling end receives the continuous frame data sent by the cloud end and the corresponding pre-labeling file, and after a correction instruction for the pre-labeling file is received, the labeling file is corrected according to the correction instruction, and a target labeling result is obtained. By adopting the scheme, the manual time for marking the continuous frame data is shortened, the marking efficiency of the continuous frame data is improved, and the marking cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a system, method and device for labeling continuous frame data. Background technique [0002] In the field of autonomous driving, the perception module uses the data of various sensors and high-precision map information as input, and after a series of calculations and processing, it can accurately perceive the surrounding environment of the autonomous driving vehicle. At present, the mainstream of automatic driving perception algorithm adopts deep learning method, which needs to use a large number of labeled data sets to train the model, so the ability to generate a large amount of labeled data faster and more efficiently is the key to automatic driving perception. [0003] Currently, most of the labeled data are manually labeled, including 2D images, 3D lidar point cloud data, etc., which is a very slow and inefficient process. It requires people to sit in front of a ...
