Embodiment 1
[0028] Embodiment one: see figure 1 Shown, a kind of real-time online traffic state detection method based on traffic monitoring video, comprises setting a video processor (the TMS320C66x DSP series TMS320C6670 product of Texas Instruments) correspondingly on each monitoring equipment, each described video processor passes network module (Ethernet or 2G\3G\4G wireless network) to connect with the remote server, where:
[0029] The video processor reads the video image corresponding to the monitoring device, calculates the gray value X of each pixel in each frame of the picture according to the obtained picture, and compares it with the prestored parameter value X -1 Compare, when greater than X-X -1 >0, then num i _1=num i _1+1, otherwise num i _0=num i _0+1, by num i _1 and num i _0 value collection to form real-time gray value ei=(num i _1,num i _0), the road congestion degree c observed on the video processor is evaluated by the kernel method i , and then upload t...
