A transmission method and transmission system for an intersection vehicle image collection system

Abstract

The invention belongs to the technical field of vehicle image information processing, and discloses a transmission method and a transmission system of a vehicle picture collection system at an intersection. A plurality of data transfer devices are used to form a transfer device resource pool, and all cameras can communicate with any data transfer device. Transmission; set up a monitoring server, the monitoring server can communicate with all cameras and transfer devices; every once in a while, the monitoring server obtains the picture generation rate of all cameras and the data transfer device, and according to the known bandwidth of all transmission channels, Based on the network maximum flow FF algorithm, the maximum flow is obtained, and the connection between different cameras and transfer devices is readjusted according to the load conditions of each camera and transfer device. The invention can reduce the delay of image transmission, give these cameras high priority, and when readjusting the connection between different cameras and the transfer equipment, the camera with high priority is preferentially adjusted.

Description

technical field [0001] The invention belongs to the technical field of vehicle image information processing, and in particular relates to a transmission method and a transmission system of an intersection vehicle picture collection system. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Different cameras play different roles, including recording video streams, uploading snapshot information, and so on. The intersection vehicle image collection system is one of the applications. The system places cameras above the traffic lanes in all directions at the intersection to capture the picture information of each passing vehicle, and stores the picture of each vehicle to the cloud storage system through the network. The system consists of three parts, namely the front-end camera, and each high-definition camera at the intersection is responsible for capturing pictures of each vehicle; [0004] Data transf...

Problems solved by technology

This will greatly affect the efficiency of the public security department. For example, in some emergencies, it is necessary to view the vehicle picture information at the current intersection, and the viewing efficiency is reduced due to the delay problem.

[0008] (2) In the existing technology, only one data transfer device is installed in the vehicle image collection system at the intersection, which is likely to cause image congestion on the data transfer device and increase the image transmission delay

[0009] (3) In the prior art, priority setting transmission is not carried out, which will affect the efficiency of picture viewing. For example, in some key defense road sections, it is necessary to view the pictures collected by multiple cameras in this road section in real time, and because no priority is set , then the pictures collected at all intersections in the city will be transmitted with the same probability, thus preempting the picture transmission bandwidth of the fortified road section and affecting the viewing efficiency of this area
