Embodiment Construction

[0020] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the described embodiment.

[0021] This embodiment requires that each remote traffic monitoring site has several cameras. The lens and pan / tilt of the camera are controllable. Each monitoring thread has a relatively well-configured computer as the basic monitoring center, which includes a video capture compression card and video service software. The monitoring center sends real-time images. It can also control the camera switching, lens, and pan / tilt action of the scene. At the same time, it can receive control commands sent by the monitoring center and perform corresponding operations. The...

Abstract

The invention uses typical structure of socket client / server. The invention is composed of video data process module for monitoring sites, module for transmitting video data and data of traffic flow at server end, and module for receiving and playing back video data at client end. The video data process module implements: collecting video data in real time and storing video data dynamically, detecting vehicle flowrate dynamically, playing back video images in real time, and controlling play back of video files. The module for transmitting video data and data of traffic flow is in charging of management on network transmission of video compression card, and sending video flow through multicast in network. The module for receiving and playing back video data is in use for receiving as well as storing and playing back the video flow in real time. Finally, the invention reaches target for monitoring and controlling crossroads in city, and recognizing and detecting freight flow.

Description

technical field [0001] The invention relates to an identification method in the technical field of transportation, in particular to a remote monitoring and vehicle flow identification and detection method at an urban intersection. Background technique [0002] Intelligent Transportation System (ITS) is an ideal solution to many transportation problems brought about by economic development, and it represents the development trend of transportation system. With the maturity of micro-embedded technology, GPS satellite positioning technology, communication technology and geographic information system (GIS), the development and application of urban traffic information system based on GPS / GIS is getting more and more attention in the field of intelligent transportation system, and it shows that huge economic and social benefits. The urban traffic information system provides important technical support and information platform for intelligent traffic; it reflects the real-time and...
