Problems solved by technology

[0005] In addition, most of the current pedestrian tracking applications are processed using a centralized processing framework. Although this framework can complete most pedestrian tracking tasks, the required computing resources and time consumption are very large. In many unaffordable in latency-sensitive applications

Embodiment Construction

[0059]The present invention will be described in detail below with the accompanying drawings and embodiments.

[0060]Such asfigure 1 As shown, the cross-camera pedestrian tracking system based on the blockchain of the present invention includes: an entrance module, a data collection module, a short trajectory generation module, a tracking module, an output module, and a blockchain sharing module;

[0061]The specific implementation process of the above modules is as follows:

[0062]1. Entry module

[0063](1) The user enters the user name and password through the text input box, and the system searches the database to find whether the information corresponding to the user name name is consistent with the user input; if the information is consistent, the user logs in successfully and returns all the user information I; If the information is inconsistent, it prompts that the password is wrong or the user does not exist, and exit the module;

[0064](2) Obtain the user's authority level from I. If ...

Abstract

The invention relates to a cross-camera pedestrian tracking system and method based on a block chain. The cross-camera pedestrian tracking system comprises the following six modules: an entrance module, a data collection module, a short track generation module, a tracking module, an output module and a block chain sharing module. According to the invention, pedestrian tracking tasks and functionsdeployed at a camera end in a cross-camera scene are mainly completed. A user can utilize the system to complete tracking of pedestrians in a cross-camera monitoring scene, and consistency of pedestrian labels in the cross-camera monitoring scene is kept.

Description

Technical field[0001]The invention relates to a cross-camera pedestrian tracking system and method based on block chain, in particular to a near real-time pedestrian tracking system that uses block chain technology to complete cross-camera tracking pedestrian information sharing. It does not rely on a central server and can be deployed At the camera end, it provides the historical movement trajectory of pedestrians in the cross-camera scene, which belongs to the field of surveillance and security.Background technique[0002]At present, surveillance videos collected by surveillance cameras are generally uploaded to a central server, and the server performs video analysis tasks, such as pedestrian detection and pedestrian tracking. However, in practical applications, due to the limitations of network speed, server capacity, server performance and other factors, the task of centrally tracking pedestrians on a central server is very difficult and cannot meet the demand for near real-time ...
