Heat radiation under varying environment, different distance for the object is different, therefore, will accurately detect the forest fires of distant place,
It is really achieved incipient fire early warning it is necessary to obtain the distance of current weather condition and monitoring position and burning things which may cause a fire disaster.At present,
Great majority gather, using thermal imaging system, the infrared forest fire detection system that thermal image is set up, and to determine according only to single threshold value is
No have the condition of a fire it is difficult to adapt to the change of various climate and weather conditions, also has minority infrared forest fire detection system to add number
Word map, for obtaining the range information around thermal imaging system, but does not obtain current weather condition information.

The information such as ambient temperature, ambient humidity and visibility.
It should be noted that above-mentioned monitoring position can be the position that monitoring device is located, in a kind of optional applied field
Under scape, in forest zone, scattering device has multiple monitoring steel towers, and the top of multiple monitoring steel towers is provided with head, monitoring device
It is arranged on head, head can rotate, so that multiple monitoring device gathers thermal image and the Monitoring Data in forest zone.
Wherein, monitoring device includes thermal imaging system, diastimeter and meteorological sensor.Thus, in above-mentioned application scenarios,
Monitoring position can be the position of head.For multiple monitoring devices, may be mounted on the head of diverse location,
The multiple monitoring devices being located on different heads can carry out information exchange by network and Surveillance center between.
Step S14, the gray value according to thermal image and Monitoring Data are calculated suspicious burning things which may cause a fire disaster threshold value.
In above-mentioned steps S14, thermal image can be thermal imaging system detects infrared energy by noncontact, and by infrared energy
Amount is converted to the signal of telecommunication, and then forms thermal image, wherein it is possible to calculate to temperature value by above-mentioned thermal image.
In thermal image, can intuitively represent the height of temperature with different colors, for example, it is possible to represent temperature with redness
Degree is high, low with blue scaling temp.Can be by the distance, ambient temperature, ambient humidity and the visibility letter that monitor
Breath calculates atmospheric transmittance, then calculates above-mentioned suspicious burning things which may cause a fire disaster threshold value by the gray value of atmospheric transmittance and thermal image.

Value, to reach real-time update suspicious burning things which may cause a fire disaster threshold value, can effectively improve the accuracy rate of the differentiation of the condition of a fire.
Step S18, when the gray value that there are any one or more pixels in thermal image is more than suspicious burning things which may cause a fire disaster threshold value,
Determine in target area, there is suspicious burning things which may cause a fire disaster region.
Specifically, by the magnitude relationship of the gray value of compared pixels point and suspicious burning things which may cause a fire disaster threshold value, when gray value be more than can
During doubtful burning things which may cause a fire disaster threshold value, determine in target area, there is suspicious burning things which may cause a fire disaster region, when gray value is less than or equal to suspicious burning things which may cause a fire disaster threshold value
When, determine in target area, there is not suspicious burning things which may cause a fire disaster region, it is possible to further determine in target area the no condition of a fire.
It should be noted that suspicious burning things which may cause a fire disaster region can be gray value be more than suspicious burning things which may cause a fire disaster threshold value pixel set.
Also, it should be noted the method that whether there is the region more than suspicious burning things which may cause a fire disaster threshold value in judgement thermal image can be led to
Cross following manner：First kind of way：By comparing the gray value of each pixel and suspicious burning things which may cause a fire disaster threshold value in thermal image
Size, when there is the pixel that gray value is more than suspicious burning things which may cause a fire disaster threshold value in thermal image, determining and judging exist in thermal image
Region more than suspicious burning things which may cause a fire disaster threshold value.The second way：Thermal image is divided into many sub- thermal images, calculates every successively
The gray value of individual sub- thermal image, when the gray value of any one sub- thermal image is more than suspicious burning things which may cause a fire disaster threshold value, determines thermal map
There is the region more than suspicious burning things which may cause a fire disaster threshold value in picture.The third mode：Select any one region in thermal image, compare
