Monitoring system for marking road section information by utilizing vertical and horizontal angles of camera

Abstract

The invention discloses a monitoring system for marking road section information by utilizing vertical and horizontal angles of a camera, which comprises a data acquisition system arranged at a monitored road junction, a control system arranged in a monitoring room, a transmission system and a video display device. The video monitoring system for automatically marking road section information also comprises a road section information marking module for marking the road section name and direction of the road junction. The data acquisition system comprises the camera, a pan / tilt, a horizontal angle measuring device and a vertical angle measuring device; and the horizontal angle measuring device and the vertical angle measuring device are connected with the pan / tilt and measure the horizontal angle horizontally rotated and the vertical angle of the pan / tilt. The monitoring system solves the problem that the traffic video monitoring system in the prior art can only mark the road section name by means of experience and memory of monitoring personnel, and is a convenient and quick traffic video monitoring system for automatically marking the road section information.

Description

technical field [0001] The invention relates to a video monitoring system, in particular to a monitoring system and a method for marking road section information by using the vertical and horizontal angles of a camera. Background technique [0002] The road traffic video monitoring system is an important part of the road traffic command center, and it is a window to understand the city's traffic conditions and security conditions; the establishment of a road traffic video monitoring system is an important link in the realization of an intelligent traffic system, through which the road traffic can be reflected in real time situation, accurately grasp the flow of vehicles and pedestrians around the monitored intersection or road section, and traffic security conditions, etc., and provide commanders with rapid and intuitive information, so as to make accurate judgments on traffic accidents, traffic jams, and emergencies. Response, play a comprehensive governance effect. [000...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is that the traffic video monitoring system in the prior art can only rely on the experience and memory of the monitoring personnel to mark the name of the road section, and cannot quickly and accurately identify the name of the road section and its direction. Labeling affects the reflection of road conditions in real time, so a monitoring system that can automatically label the name and direction of the road section displayed in the current video screen and use the vertical and horizontal angles of the camera to mark the road section information
