Problems solved by technology

[0004] However, in the above implementation, only some video frames in the video are selected for labeling according to a certain interval, thus causing a waste of unlabeled video frame resources in the video, which greatly reduces the amount of sample data obtained as a whole, and the entire video resource utilization drops

Abstract

The embodiment of the invention discloses a method and device for acquiring annotation data, and belongs to the technical field of image processing. In the embodiment of the invention, a labeling device performs labeling according to first labeling data, detected in a first video frame, of a first target object and second labeling data, detected in a second video frame, of the first target object; and annotation data of the first target object in each non-annotated video frame in N non-annotated video frames between the first video frame and the second video frame is determined. According to the embodiment of the invention, the annotation data of the video frame in which the target object is not detected can be determined according to the annotation data in the video frame in which the target object is detected, so that the annotation efficiency can be ensured, the overall sample data volume can be greatly increased, and the resource utilization rate of the whole video is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method and device for acquiring annotation data. Background technique [0002] With the development of AI (Artificial Intelligence, artificial intelligence) technology, the scenarios where AI algorithms are applied are becoming more and more complex. In various complex application scenarios, a large amount of accurate sample data is required to train the corresponding AI algorithm. Therefore, it is extremely important to quickly obtain a large amount of accurate sample data. [0003] Currently, for an AI algorithm used to detect a target object in an image, sample data can be obtained by marking the target object in a video. Wherein, in an implementation manner, the labeling device may start from a certain video frame in the video, select video frames at a certain interval, and label the target objects in the selected video frames to obtain the target ob...
