Abstract

The invention provides a labeling method and device for multiple video frames, equipment and a storage medium, and relates to the technical field of image processing. The labeling method for the multiple video frames comprises the following steps: acquiring a plurality of video frames collected for the same area; performing three-dimensional reconstruction according to the plurality of video frames to obtain a three-dimensional reconstruction scene corresponding to the region; marking based on the three-dimensional reconstruction scene to obtain marking information in the three-dimensional reconstruction scene; and projecting the annotation information in the three-dimensional reconstruction scene to the plurality of video frames to obtain the annotation information in the plurality of video frames. According to the method, batch annotation of the video frames can be realized, the annotation efficiency of the multiple video frames can be effectively improved, and the labor cost of annotation work is reduced.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method, device, device and storage medium for labeling multiple video frames. Background technique [0002] In the field of unmanned driving technology, the image perception algorithm is widely used as the core algorithm. It can use machine learning to locate and identify obstacles based on continuous image frames collected by unmanned driving equipment. During the training process of machine learning, it is necessary to mark the target object in the image frame corresponding to the training sample data. [0003] At present, most of the annotations used in image perception algorithms come from manual annotations, and annotators only annotate single-frame images. Such an annotation method will consume a lot of manpower and material resources, and continuous frame annotation is required in the field of automatic driving, which greatly increases the workloa...
