The invention provides a multi-target tracking method, and the method comprises the steps of obtaining a to-be-processed image which comprises a plurality of frames of images; determining a newly added target in the Nth frame of image, wherein the newly added target is a detection target which is not successfully matched with the plurality of predicted tracking targets in the plurality of detection targets in the Nth frame of image; respectively matching the newly added target with a predicted tracking failure target in a predicted tracking failure target library to obtain a matching result, wherein the prediction tracking failure target is a prediction tracking target which is not successfully matched with the plurality of detection targets in the plurality of prediction tracking targets in the Nth frame image, and the prediction tracking failure target library is a set of one or more prediction tracking failure targets; and according to a matching result, determining identifiers of a plurality of detection targets in the Nth frame of image. According to the method provided by the invention, the target tracking effect under the shielding condition can be improved, the problem of target ID hopping is also reduced, and meanwhile, the precision of a multi-target tracking algorithm is improved.
Description
technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a multi-target tracking method, device and electronic equipment. Background technique [0002] The amount of video data is currently showing explosive growth. Tracking and large-scale labeling of multiple targets in video data requires a lot of manpower and time. How to carry out efficient and large-scale video data labeling and reduce production costs is an urgent problem to be solved. [0003] In the existing technology, the target detection algorithm based on deep learning is more and more widely used in practical engineering. By extracting features from video data and performing detection and recognition, the identification of targets and the labeling of bounding box information are completed, which has become a large-scale The main solution for video data annotation. [0004] However, in practical applications, problems such as frequent jumps...
