Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the application.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the application.
For forest fire monitoring, the monitor mode of country's mainstream is video monitoring system at present, this is traditional cities prison
The simple extension of control summarizes acquisition video image by microwave, and by being accomplished manually centralized watch, but, direct surveillance is easily made
At naked eyes fatigue, the fire behavior in video is caused to be not easy to be found, in addition, the video line of monitoring center is more, direct surveillance
It not can guarantee and supervise one by one, therefore easily cause and fail to report.That is, the disadvantage of traditional video surveillance is that rate of failing to report is very high.
In view of this, the application provides one kind based on video technique, the Forest Fire of computer vision technique is combined
The monitoring method of calamity, the virtual bench for applying this method and entity device and the monitoring system for realizing this method, it is specific interior
Appearance will be illustrated by following multiple embodiments.
Embodiment one
Referring to Fig. 1, Fig. 1 is a kind of flow diagram of the monitoring method of forest fire provided by the embodiments of the present application.
As shown in Figure 1, method includes the following steps:
S101: the video information that video camera is sent is obtained；Wherein, the video camera setting is aerial in the height of forest, is used for
Shoot the video information of forest；
Specifically, the mode for being similar to traditional video monitoring, manually checking, the present embodiment also need first in forest
It is middle to establish perfect video monitoring system, i.e., a large amount of camera shootings are set in forest high-altitude by modes such as plateau, high tower or electric poles
Head, so that monitoring range be made to cover entire forest location as far as possible.The video pictures of camera shooting can be by wired
Or it is wirelessly transmitted to specific monitoring device, it is handled for analysis.
In some embodiments, monitoring device can be integrated to video camera, i.e., comprising storage in each video camera
There is the memory of relative program and execute the processor of the program, to be the shooting that video can be achieved at the same time in video camera front end
It is handled with analysis.So set, being transmitted to same fixed location relative to traditional all videos for shooting each video camera
For the mode uniformly checked, it is not necessary that the data line or wireless network that are used for data transmission are specially arranged for each video camera,
Therefore installation cost can be reduced during installation, while being also convenient for safeguarding.
S102: each frame picture is extracted from the video information and is sequentially input to fire detection mould trained in advance
Type respectively obtains the quantitative value of target identification object in each frame picture；Wherein the target identification object includes target flame
Object and target smog object；
In the specific implementation, step S102 may is that extracts each frame picture from the video information；It will be described every
One frame picture is sequentially input to the fire detection model based on deep neural network model training；Distinguished by object detection algorithms
Obtain the quantitative value of target identification object in each frame picture.
Specifically, what fire detection model was realized particularly directed to static picture when being detected, therefore, it is necessary to first
Each frame tableaux is first extracted from dynamic video.Above mentioned each frame picture is exactly minimum unit in image animation
Single width image frame, a frame are exactly a static picture.After one frame picture is input to fire detection model, fire detection mould
Whether type in picture to detect input includes target identification object (i.e. flame or cigarette automatically according to preset sample and mark
Mist), if the quantity for counting target identification object comprising if.
Wherein, fire detection model is formed based on deep neural network model training, more specifically, used depth
Neural network can be convolutional neural networks (Convolutional Neural Networks, CNNs), and CNNs is that one kind includes
Convolutional calculation and the feedforward neural network with depth structure, are one of the representative algorithms of deep learning (deep learning),
Certainly, it in addition to this can also be realized using other algorithms of deep learning, to this without limiting.
Further, the training process of fire detection model may is that the fire picture sample for obtaining preset quantity；By institute
It states fire picture sample and is input to the deep neural network model constructed in advance, and the target in the fire picture sample is known
Other object is identified one by one, to obtain the fire detection model.
That is, it is necessary first to prepare a large amount of pictures for occurring to shoot after forest fire or video pictures etc. as sample
This, wherein sample can be oneself shooting and be also possible to obtain by internet or other approach, be then based on common
Deep neural network model, such as Mobilenet0.25 are identified the target identification object in sample one by one, i.e., will be every
Everywhere flame in one width picture (or picture) or the position where smoke characteristics are identified, wherein the work being identified
Work can realize (such as SSD algorithm) by object detection algorithms, object detection be classical problem in computer vision it
One, task is the position for removing to mark objects in images with frame, and provides the classification of object.That is, object detection algorithms
Exactly specific identification object is marked by frame, to provide position and the classification of identification object.
In the specific implementation, when training fire detection model, need to mark the flame and smog in sample in the form of frame,
And provide different signature identifications respectively to flame and smog, it is popular for, i.e., " inform " model being trained to: including
The information of certain signature identification belongs to " flame " and includes that the information of another signature identification belongs to " smog ", thus fire detection
Model can identify pair between identification object by deep neural network model and object detection algorithms " study " this feature
It should be related to；And in the good fire detection model of application training, be based on object detection algorithms detection picture in whether include
Flame or smog (whether being substantially in detection picture comprising corresponding signature identification), if comprising will be in picture by frame
Flame and smog mark (position), and can designate that the identification object in frame is flame or smog (classifying).
In addition, being sequentially input by each frame picture to based on deep neural network model training in some embodiments
It can also include: that each frame picture is zoomed into pixel identical with training sample before fire detection model.
Specifically, in order to shorten the detection time of the fire detection model trained and improve accuracy in detection, in training
Before the fire detection model, the pixel of all fire picture samples can be zoomed to all unanimously, such as 300*300, because
This also needs first to zoom to the pixel of picture to be measured and training sample when being detected using the fire detection model
This is consistent, consequently facilitating fire detection model is detected.
S103: if the quantity of the target identification object is greater than 0, the monitoring result that fire has occurred is obtained.
Specifically, the quantity of target identification object refers to the sum of flame quantity and smog quantity, as long as detecting fire
Flame or smog it is any, that is, be considered as generation fire.It should be noted that since flame and smog are uncountable noun, because
This, the flame quantity and smog quantity being previously mentioned in the application are actually referred to when detecting using object detection algorithms,
The quantity for the frame that flame or smog are marked.
In addition, it should be noted that, forest fire usually has very high concealment, therefore only rely on flame identification fire
There is significant limitation, i.e., is usually in ground location when just occurring due to fire, and video camera is in order to covering biggish model
Enclose, be generally arranged at high aerial, therefore blocking due to trees, fire just occurred and the intensity of a fire it is smaller when video camera be difficult in time
Shooting has occurred that sprawling in actually discovery so as to cause fire.In consideration of it, would generally be with big when since fire occurs
The generation of smog is measured, and smog is shot (relatively fiery earlier because the lighter reason of its density can flow upwards convenient for video camera
Flame), therefore, identify that fire behavior is of great significance by smog when fire occurs.But, traditional video monitoring, artificial
The mode checked is usually predominantly flame characteristic when fire occurs for identification, and can not utilize smoke characteristics well, and reason exists
There is very strong similitude in the visual signature of smog and sky medium cloud, while can also be influenced by the greasy weather, therefore shoots into video
It is visually difficult to accurately distinguish after picture, additionally due to the video line of monitoring center is more, i.e., everyone needs while checking more
A monitored picture, the accuracy and timeliness of manual identified smog further reduce.
Based on this, using in deep neural network algorithm and computer vision technique in the technical solution of the embodiment of the present application
Object detection algorithms, so that identification to flame characteristic and smoke characteristics is realized by artificial intelligence technology, so that identification knot
Fruit has very high robustness relative to conventional method.In addition, by combining two kinds of recognition results of smoke characteristics and flame characteristic,
Keep whole detection result more accurate and reliable.
The technical solution that embodiments herein provides can include the following benefits:
When using technical solution provided by the embodiments of the present application, the view for the video camera shooting being arranged in forest is obtained first
Frequently, the picture in video and as unit of frame is extracted, the picture of extraction is inputted into fire detection model later, to pass through calculating
Machine vision technique (artificial intelligence technology) identifies in the picture of input whether include target identification object (i.e. after generation fire
Flame and smoke characteristics), finally export the result of identification.So set, not using traditional artificial checking monitoring picture to sentence
It is disconnected that fire whether occurs, but monitored picture is identified by artificial intelligence, as long as the sample size in detection model is enough,
The result so identified is just accurate enough, and the detection model learning ability based on artificial intelligence is very strong, therefore with using
The time accuracy of increasingly longer identification also can be higher and higher.That is, using the technical solution of the application to forest fire
When being monitored, it can save labour turnover under the premise of guaranteeing that monitoring effect is good.
In order to improve the forest fire in above-described embodiment monitoring method practicability, the application also provides following improvement
Scheme.
Embodiment two
Referring to Fig. 2, Fig. 2 is the process signal of the monitoring method of another forest fire provided by the embodiments of the present application
Figure.As shown in Fig. 2, method includes the following steps:
S201: the video information that video camera is sent is obtained；Wherein, the video camera setting is aerial in the height of forest, is used for
Shoot the video information of forest；
S202: each frame picture is extracted from the video information and is sequentially input to based on deep neural network model and is instructed
Experienced fire detection model respectively obtains the quantitative value of target identification object in each frame picture by object detection algorithms；Its
Described in target identification object include target flame object and target smog object；
S203: if the quantitative value of the target identification object is greater than 0, assessing every place's target identification object, point
It does not show that confidence level scores, and non-maxima suppression is carried out to target complete identification object；
S204: the size of the confidence level scoring and preset score threshold, if confidence level scoring is less than in advance
If score threshold, then give up corresponding target identification object；
S205: it obtains in each frame picture by the assessment and remaining target identification pair after the non-maxima suppression
The quantitative value of elephant obtains all remaining target identifications pair if the quantitative value of the remaining target identification object is greater than 0
As the position in the frame picture；
S206: quantitative value, position and the confidence level scoring of the output remaining target identification object, while obtaining
The monitoring result of fire occurs.
Specifically, the process of the specific implementation of step S201 and S202 in the present embodiment is referred in embodiment one
Identical content realizes that and will not be described here in detail.And the difference between this embodiment and the first embodiment lies in, it is being detected in the present embodiment
There are when target identification object in video pictures, a series of calibrations have been carried out to testing result, specific as follows:
For step S203 and S204, the target identification in each frame can be provided by common method in the prior art
The confidence level of object scores, i.e., it is required target identification object " possibility " that the object identified to every place, which provides it,.This can
Confidence score can be indicated with a decimal between 0~1, such as 0.35 indicates that the object in the frame identified is mesh
" confidence level " (or being " possibility ") for identifying other object (flame or smog) is 35%, in addition, in order to guarantee not obtain standard
The lower recognition result of true property, can be set a score threshold, such as 0.60, in this case, all scores are no more than
The frame (i.e. frame of the confidence level lower than 0.60) of the score threshold, will be rejected, other frames are then retained.It should be noted that
It must be 0.60 that the score threshold, which does not limit, but can go to adjust according to actual needs, but it is not recommended that be arranged too
Greatly, because score threshold setting it is bigger, it is concluded that the time that the recognition result of fire has occurred is more late, be so unfavorable for early
It was found that fire behavior.
In the related technology, the process of object detection algorithms identification special object can usually pass through classifier
(Classifier) Lai Shixian directly can be to mark while positioning and classification when carrying out Classification and Identification by classifier
Each frame provide confidence level scoring.
In addition, non-maxima suppression (Non-Maximum Suppression, NMS), also referred to as non-maximum suppression care for
Name Si Yi be exactly inhibit be not maximum element, it can be understood as local maxima search, is a kind of edge thinning technology, one
As be applied to " thinned " edge.
For the application, by taking flame as an example, since flame belongs to uncountable noun and it does not have well-regulated shape, because
This, should be considered as the continuous flame that quantity is 1 for certain in video pictures, when being detected using object detection algorithms,
It may be marked by the frame of multiple and different sizes, and generally will appear between multiple frames and completely include or largely intersect
The case where, and the flame that substantially multiple collimation marks go out is same place flame, therefore in this case it is necessary to passes through NMS technology
The maximum frame of range is found out as the indicia framing at this.
Specifically, being to the algorithm of the progress non-maxima suppression of each pixel in gradual change image: by the side of current pixel
Edge intensity is compared (for example, for being directed toward the direction y with the edge strength of the pixel on positive gradient direction and negative gradient direction
It is then compared by pixel with the pixel above and below it)；If the edge strength of current pixel with have the same direction
Mask in other pixels compared to being the largest, which will be retained, and otherwise, which will be suppressed that (repressed value is usual
It is arranged to 0).
After carrying out confidence level scoring and non-maxima suppression, if the quantity of remaining frame is greater than 0, it can be concluded that every
Locate the position of target identification object (each frame), it later can be by the quantity of remaining target identification object (frame), view where it
Position and confidence level scoring output in frequency picture.It in the specific implementation, can be with after fire detection model output recognition result
It is stored into monitoring device, monitoring device finally obtains the monitoring result that fire has occurred, and then can be to preset intelligence
Energy equipment, such as the smart phone or computer of related personnel, send warning message.Further, monitoring device is also if necessary
Above-mentioned recognition result can be sent to smart machine in the form of picture or video, in order to manually check, thus relevant people
Member can intuitively observe the details of fire behavior.It further, can also be by the flame in recognition result in some embodiments
The quantity of frame and smog frame is counted and is exported respectively.
When using technical solution provided in this embodiment, relative to embodiment one, pass through confidence level scoring and non-maximum
Inhibit that the lower recognition result of confidence level can be excluded and repeat the recognition result of statistics, to further increase testing result
Accuracy.
In order to which the technical solution to the application is described in detail, will be said below by a specific example
It is bright.
