Problems solved by technology

In 2017, the SORT algorithm based on deep learning target detection, the SORT algorithm took into account the tracking effect and speed, and achieved good results, but it is easy to cause tracking failure due to occlusion
[0003] It can be seen that there are still many technical problems in the multi-target tracking technology in the prior art, and it is difficult to meet the actual needs.

Embodiment 1

[0066] It should be noted that the solution of the present invention can be implemented on the field side, and can also be implemented on the server side. That

[0070] The third tracking chain is assigned to the identified target objects in the sequence of identification.

[0075] A first number is determined according to the number and the speed, and the third tracking chain is generated according to the first number.

[0078] Optionally, the first tracking chain and the second tracking chain include speed data and position data;

[0083] Wherein, the distance between the first moment and the second moment is less than a preset threshold.

[0086] Optionally, the state includes not comatose, comatose;

[0089] If the first target object recognition fails, then add 1 to the non-coma times n2, and record the corresponding time.

[0092] before the calculation of the similarity between the first tracking chain and the second tracking chain, further

[0095] Calculate the number of ...

Abstract

The invention provides a multi-target tracking method and system based on a tracking chain. The method comprises the following steps: identifying a first target object in a monitoring image according to a preset interval, and generating a first tracking chain according to an identification result; when the identification of the first target object fails, modifying the state of the first tracking chain; generating a second tracking chain for the newly recognized second target object; the similarity between the first tracking chain and the second tracking chain is calculated, and the first tracking chain and the second tracking chain are connected in series according to the similarity; according to the method, synchronous tracking of multiple target objects can be simply and efficiently achieved, tracking failure caused by shielding is avoided, and higher reliability is achieved.

Description

A tracking chain-based multi-target tracking method and system technical field The present invention relates to the technical field of image recognition, in particular, to a kind of multi-target tracking method based on tracking chain. methods, systems, electronic devices, and computer storage media. Background technique [0002] Multiple object tracking (Multiple Object Tracking), in short, its main task is to give a graph Like a sequence, after identifying the object in the image, the same object in different frames is represented by a Trace id, So as to complete the task of target tracking. Of course, these objects can be arbitrary, such as pedestrians, vehicles, various animals, etc. Many goals Tracking is a hot spot in computer vision technology, and it is also a difficult point in practical applications. In 2017, the target detection based on deep learning SORT algorithm, the SORT algorithm takes into account the tracking effect and speed, and achieves good ...
