Embodiment 1

[0051] This embodiment provides a method for intelligent identification and early warning of group fog, such as figure 1 shown, including the following steps:

[0052]Step S1: collecting video images of the video surveillance area, and extracting moving objects in the video images;

[0053] In the case of a static background, if the external lighting conditions remain unchanged, the complete background in the video image remains unchanged without considering the noise; when the target movement is visible, the grayscale between the target and the background must be There is a large difference, so the moving target in the video image can be extracted by the background difference method, which specifically includes the following steps:

[0054] Step S101: Assuming that the complete background image of the current video image sequence is B(x, y), the complete background is estimated from frame k to frame k+n, namely:

[0055] B(x,y)=O b [f k (x,y),f k+1 (x,y)... f k+n (x,y)]...

Abstract

The present invention discloses an intelligent radiation fog identifying and early warning method and apparatus. The method comprises the steps of firstly, extracting a moving target in a video image; then, identifying features of the moving target and determining whether the moving target is the radiation fog; and finally, releasing radiation fog early warning information. The apparatus comprises a main control module, an intelligent fog detection module, an intelligent radiation fog identification and analysis module, and an early warning signal release module that are all connected with the main control module. Compared with the prior art, the apparatus is highly integrated, and optical detection and video detection are combined, so that the problem of singleness of the radiation fog detection technology is solved, and the method and apparatus have advantages of high detection effectiveness and high accuracy.

Description

technical field [0001] The invention belongs to the technical field of fog recognition and early warning methods for road traffic vehicles, and in particular relates to a fog intelligent recognition and early warning method and a device thereof. Background technique [0002] Cluster fog, which is called radiation fog in meteorology, is the fog formed by directly cooling the air layer close to the road surface due to the radiation cooling of the ground at night. The conditions for the formation of fog clusters have three major elements: clear night, breeze and sufficient water vapor. The cloud fog is different from the foggy weather we usually see. It is blocky and has a relatively small control range. It is like a large pile of cotton wool falling on the ground. Fog also has the characteristics of small range, long accumulation time, easy drift, and strong suddenness. [0003] In recent years, with the rapid growth of the number of motor vehicles in my country, heavy traff...
