Embodiment 1

[0039] Embodiment one: see figure 1 As shown, a real-time acquisition device for road conditions based on traffic monitoring video includes a video processor, a network module, a remote server, a data pusher and a data receiver, wherein:

[0040] (1) Video processor: set on the monitoring equipment at each intersection, used to read the video images on the monitoring equipment and analyze the video images. The video processor can choose TMS320C66xDSP series TMS320C6670 products from Texas Instruments. The chip operating temperature is at Between -40 degrees and 100 degrees, it can meet the requirements of outdoor work;

[0041] (2) Network module: a wireless network or a wired network, used to connect the video processor and the remote server, and transmit data information. The wired network is Ethernet. If a wireless network is selected, one of the 2G\3G\4G networks can be selected ;

[0042] (3) remote server: receive the analysis result sent by the video processor, and se...

Abstract

The invention discloses a road information real-time acquisition device and method based on a traffic monitoring video. The device is characterized in that the device comprises a video processor, a network module, a remote server, a data pusher and a data receiver. The video processor reads a video image corresponding to a monitoring device. According to acquired pictures, the grayscale value X of each pixel in each picture is acquired, and is compared with a pre-stored parameter value X-1. A nuclear method is used to assess road congestion extent ci, and ci is uploaded. A remote server carries out real-time analysis to acquire a road congestion extent value C. The data pusher transmits the information of a congested road to the data receiver, and the data receiver outputs the information. According to the invention, the video processor analyzes the real-time image grayscale; the nuclear method is used to assess and upload the congestion extent; the data pusher transmits the information in real time; the receiver carries out real-time broadcasting; a driver can acquire the road information in real time and can timely plan a route; and congestion is reduced.

Description

technical field [0001] The invention relates to a method for identifying road traffic conditions, in particular to a device and method for real-time acquisition of road conditions based on traffic monitoring video. Background technique [0002] Traffic is the foundation of modern society and the lifeblood of human society and economy. People's social behavior is closely related to traffic. In a city, there are a large number of motor vehicles and non-motor vehicles, and the intersections and road sections are complicated. It is very complicated to deal with such a large-scale, dynamic, and highly uncertain distributed system for effective control. work. In the case of no new traffic roads, it is an effective way to quickly solve urban traffic problems through reasonable traffic control to improve the utilization efficiency of roads, and then improve the traffic efficiency. [0003] However, traffic congestion and congestion are becoming more and more serious now. The reas...
