Region of interest extracts dark areas on background image；S22), the criterion numeral of interesting image area gray value of image and contrast is established
According to library, each month is selected one day, the image that each hour camera provides in this day is extracted, to the bright area in 24 width images
It is handled with dark areas, establishes the comparison of 24 moment bright areas and dark areas gray value standard and 2 regions in one day
Scale is quasi-；Gray value of image, the contrast standard in each month are established, image comparison standard database is formed；S03), to road
The video stream data that video camera provides carries out fuzziness identification using bis- fuzzy algorithmic approaches of reblur；S04), mist monitoring judgement, figure
As pixels all in bright area gray value and java standard library gray value compare, fall is more than 500%, image bright area and
The contrast of dark areas and the contrast of annotation repository compare, and fall is more than 300%, and it is fuzzy that full figure, which has 75% area above,
When region, it is judged as greasy weather gas.
Further, the marker of bright area is the cut-off rule in lane.
Further, each month selects one day standard are as follows: fine, cloudless, fogless.
Further, LED light is according to the shape of central projection method's shadow simulation deceleration strip on road surface, and before projection, elder generation is really
The shape of the deceleration strip for needing to simulate on road surface calmly, road surface at a distance from LED light, picture at a distance from LED light, then basis
Central projection method determines the shape of deceleration strip picture, area.
Beneficial effects of the present invention: early warning system and method for the present invention take full advantage of image processing techniques, information
Processing technique can be realized quick, real-time monitoring to mist；When having monitored mist, prior-warning device is started immediately and is simulated and is slowed down
Band does not influence road when normal weather suitable for the early warning in greasy weather, but can when dense fog, group's mist occur, in time,
Quick alerting drivers slow down, and reduce accident rate；The present invention takes full advantage of existing camera on current road, stands
Bar, power supply system do not need the instrument and equipment for increasing additional expensive, do not need to construct on road yet, structurally reasonable, conveniently
Practical, low cost；The deficiency of currently used method for early warning (mobile phone short message notice, language casting and Information sign board) is made up,
It is the supplement to current greasy weather alarm mode.
