Problems solved by technology

However, in the image where the target object does not exist, there are still temporary frames of the target object at the same position, therefore, it may lead to a messy stack of a large number of temporary frames, which not only reduces the efficiency of labeling, but also increases the probability of wrong labeling

Abstract

The present application provides a method, device, and electronic equipment for marking objects in an image sequence. A specific implementation of the method includes: determining positioning data, the positioning data including positioning information corresponding to each frame of image in the image sequence; responding Based on the preset labeling operation for the target object in the target image, determine the target information of the label frame marked for the target object; the target image is an image in the image sequence; before and / or after the target image Each frame of the image is determined as the object image; according to the positioning data, determine the first positioning information corresponding to the target image and each second positioning information corresponding to the object image in each frame; according to the target information of the label frame , the first positioning information and each second positioning information, adding or adjusting a temporary frame of the target object in each frame of the object image. This embodiment improves the labeling efficiency and reduces the probability of wrong labeling.

Description

technical field [0001] The present application relates to the technical field of image labeling, and in particular to a method, device and electronic equipment for labeling objects in an image sequence. Background technique [0002] At present, in the field of unmanned driving technology, it is usually based on the image sequence collected by unmanned equipment, using machine learning methods for positioning and obstacle identification. In the training process of machine learning, it is necessary to mark the target object in the image sequence corresponding to the training sample data. In the related art, when labeling the target object in the image sequence, generally in any frame image in which the target object exists in the image sequence, first generate the label frame of the target object, and then in the other frame images of the image sequence At the same position, a temporary frame for the target object is generated, and then the labeling of the object is completed...
