Embodiment 1

[0038] Such as figure 1 Shown is the structural diagram of the urban road traffic flow detection system that can optionally use high-definition video and microwave detection according to the present invention. It can be seen from the figure that the traffic flow detection system includes a terminal acquisition unit and a control unit. The control unit The unit can be set in the monitoring room, and the terminal acquisition unit is composed of a high-definition video acquisition module and a microwave data acquisition module. Wherein, the high-definition video acquisition module adopts a 5 million-pixel high-definition digital camera and a corresponding lens, a 2 / 3 type IT CCD, an effective pixel number of 2456 (H) x 2058 (V), and a pixel size of 3.45 x 3.45 μm , using progressive scan mode, frame rate is 15fps, C lens mount, electronic shutter 1 / 15~1 / 10,000 (second), with external trigger function, digital 8 / 10 / 12bit GigE Vision; in this embodiment, all The high-definition vi...

Embodiment 2

[0051] Such as figure 2 Shown is another embodiment of the urban road traffic flow detection system that can optionally use high-definition video and microwave detectors according to the present invention. In this embodiment, the high-definition video acquisition module and the microwave data acquisition module are arranged on the road on the same section. Compared with embodiment 1, the detection system described in this embodiment has increased traffic flow data storage module and video display module, and described traffic flow data storage module is connected with described traffic flow detection data management module, and described traffic flow detection The data management module transfers the stored non-day traffic flow data into the traffic flow data storage module for data backup. The traffic flow data storage module is composed of a disk array memory. The disk array memory has at least 3TB effective capacity, a single disk capacity of 300GB, and a rotation speed o...

Abstract

The invention discloses a system for detecting urban road traffic flow by using high-definition video and microwave detection selectively. The system comprises a terminal acquisition unit and a control unit, wherein the terminal acquisition unit comprises a high-definition video acquisition module and a microwave data acquisition module; and the control unit comprises an interruption threshold value storage module, a traffic flow value comparison module, and an interruption control module. In the normal state of the system, only high-definition video acquisition module is started, so that the control unit processes and judges video information sent by the high-definition video acquisition module to acquire traffic flow data; and when the traffic flow data is abnormal, the microwave data acquisition module is automatically started. The system overcomes the disadvantages of the use of a single detector, can acquire accurate real-time data information of traffic flow in a severe environment of extremely low visibility, and lays a solid foundation for controlling and managing urban traffic by using modern technology.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a road motor vehicle flow detection system for obtaining traffic flow data based on the detection results of two different data acquisition modules of high-definition video and microwave detection. Background technique [0002] The technology of collecting traffic information based on video image processing has become an important detection technology and has been widely valued at home and abroad. Information detection equipment. The principle of the above video detection is that after the traffic video detection sensor obtains the traffic scene image through the video camera located above the road, it transmits the image to the control center, and uses the processing unit of the control center to automatically analyze the received image and further process the scene image information to obtain corresponding traffic flow data. [0003] But in above-mentioned prior art...
