Embodiment Construction

[0037] The video monitoring system consists of two parts, one is the monitoring front end, and the other is the management background. Install video cameras where surveillance is required, generally referred to as the monitoring front end. The monitoring front-end functions include collecting and encoding video. Then the video data is sent to the monitoring center through the video cable or network, which is generally called the video monitoring management background. The management background is responsible for decoding and displaying the received video data, so as to achieve the effect of real-time monitoring.

[0038] The present invention focuses on the management background, and its overall system structure module is shown in figure 1 , the system is mainly composed of camera video information acquisition module, traffic state extraction module, video splicing module, viewing angle conversion module, 3D reconstruction module and multi-level display module.

Abstract

The invention relates to a road network traffic condition monitoring system based on a video image processing technology, and belongs to the field of traffic engineering. Along with that video monitoring devices are added to a road network continuously, manual real-time monitoring of road network traffic conditions is difficult to carry out. The system monitors the road network traffic conditions in real time by processing video images to obtain useful information from the video images. The road network traffic condition monitoring system comprises a camera video information acquisition module, a traffic condition extraction module, a perspective shifting module, a video stitching module, a three-dimensional reconstruction module and a multi-level display module. A monitoring staff selects a road network traffic condition panoramic display mode as required to monitor the panoramic condition of road network traffic on a monitor wall, further a road section traffic video real-time display mode can be selected for a congestion area, and an animated display mode can also be selected to observe three-dimension reconstruction, panoramic stitching or vertical view of interested road sections so as to timely respond to traffic emergency situations.

Description

technical field [0001] The invention belongs to the field of traffic engineering and relates to a road network traffic state monitoring system based on video image processing technology. Background technique [0002] Real-time traffic status monitoring of road network is an essential part of traffic management. With the continuous increase of video surveillance equipment on the road network, it is far from enough to rely solely on manual observation and monitoring to meet the massive growth of video images. At present, the traffic monitoring centers of most big cities have already connected more than thousands or even tens of thousands of video images, but the number of monitoring personnel is limited, and it is difficult to manually monitor these video images in real time. [0003] At present, the traffic video monitoring system mostly uses the real-time images captured by the video camera to be directly displayed on the monitor (wall).
