Embodiment 1

[0016] This embodiment discloses a method for monitoring cloud fog based on big data, such as figure 1 shown, including the following steps:

[0017] S01), obtaining the video data of each camera in the monitoring road section, and preprocessing the video data;

[0018] In this embodiment, the preprocessing of the video data includes: quickly reviewing and verifying the image data, deleting duplicate information, eliminating image errors caused by problems such as spots on the cameras, and unifying the image formats of all cameras into a common jpg format;

[0019] In this embodiment, the real-time data of each camera is stored in a distributed manner and calculated in parallel.

[0020] S02), extracting an image every 5 seconds from the video image of the camera, 5 consecutive images form a time sequence; the image of the photogram forms a dynamic time sequence image over time;

[0021] S03), using the Gaussian mixture model of moving target monitoring, removing the moving...

Abstract

The invention discloses an agglomerate fog monitoring method based on big data. A big data technology is used to process and analyze massive video data (the data of multiple cameras in continuous timeperiods), and the agglomerate fog monitoring method based on a time sequence is established. Massive image information and the change rule of background pixels when agglomerate fog bursts are fully used so that a monitoring result is accurate and engineering practicality is possessed.

Description

technical field [0001] The invention relates to a big data-based fog monitoring method, which belongs to the technical field of traffic monitoring. Background technique [0002] Fog is known as the "killer" of traffic safety, especially on expressways, where it is more likely to cause major safety accidents. On November 15, 2017, the Yingshang section of Chuxin Expressway was hit by multiple vehicles due to fog, resulting in 18 deaths and 21 injuries. On November 8, 2017, 18 traffic accidents occurred in Zhoukou Taikang section of Yongdeng Expressway due to fog. According to the data published on the website of the Traffic Management Bureau of the Ministry of Public Security in 2016, there are 2,567 expressway sections with more than 3 fog episodes per year, of which 920 sections have more than 10 fog episodes per year, a certain section of the Shenhai Expressway and the Beijing-Hong Kong-Macau Expressway In a certain period, more than 120 clusters of fog occur on average ...
