Specific embodiment
It should be appreciated that specific embodiment described herein is not used to limit the application only to explain the application.
Those skilled in the art of the present technique are appreciated that unless expressly stated, singular " one " used herein, " one It is a ", " described " and "the" also may include plural form.It is to be further understood that used in the description of the present application Wording " comprising " refers to that there are the feature, program, step, operation, element and/or component, but it is not excluded that in the presence of or add Add other one or more features, program, step, operation, element, component and/or their group.
Fig. 1 is a kind of flow chart of the violated object recognition methods based on artificial intelligence in some embodiments of the application, should Violated object recognition methods is executed by violated object identification device, and violated object identification device can integrate in screening machine, can also be with Screening machine electrical connection, as shown in Figure 1, may include steps of S1-S6:
S1, x-ray image is acquired from the X-ray video that screening machine is shot with preset sampling time interval.
The X-ray video that screening machine is shot is sampled with preset sampling time interval, obtains x-ray image.X-ray image Carry article characteristics information;It is identified, identifies by safety check by safety check article in x-ray image according to article characteristics information Whether article is suspicious violated object.
In some embodiments, before step S1, the method also includes step S11: passing through according to by safety check article Time required for the shooting area of the screening machine sets the sampling time interval.
Due to it is each by safety check article be in the case where the conveyer belt of screening machine drives at the uniform velocity by screening machine shooting area, because This, the time required for shooting area of the safety check article by screening machine is constant, that is to say, that respectively by safety check article in X Presentation time in light video is constant and identical.In order to collect each X-ray figure by safety check article in X-ray video Picture needs reasonable set sampling time interval.Assuming that being 5 seconds by the time of the shooting area of screening machine;If between the sampling time It every being greater than 5 seconds, such as is set as 7 seconds or 8 seconds, in this way, being regarded by safety check article in X-ray since the time of acquisition x-ray image is greater than Presentation time in frequency then leads to not collect certain x-ray images by safety check article from X-ray video, and missing inspection feelings occur Condition;If sampling time interval is too small, such as is set as 1 second, in this way, since the time of acquisition x-ray image is less than by safety check article Presentation time in X-ray video then causes containing same by safety check article in 5 seconds presentation times of X-ray video, X Light image has been collected 5 times, also mean that it is same by safety check article done 5 safety checks identification, undoubtedly increase safety check Data processing operation amount (including multiple unnecessary repetitive operation) in the process, leads to not timely feedback by safety check object The x-ray image of product, or even occur having been passed through conveyer belt and taken away by user by safety check article, and future is remembered and it is suspicious to stop Article., in this way can be in 5 seconds presentation times of X-ray video if sampling time interval is set as 4 seconds, it substantially can be with Guarantee it is each in X-ray video an x-ray image has only been collected by safety check article, and will not there is a situation where missing inspections.Therefore, Sampling time interval cannot be greater than the time shown in X-ray video by safety check article, and sampling time interval should not be too short. Certainly, in practical application, the sampling time interval of x-ray image can carry out debugging setting according to actual needs.
Due to the position of the x-ray inspection equipment in screening machine be it is fixed, so the region that can be shot of X-ray video Range is also fixed.It can be by screening machine by the time required for regional scope captured by X-ray video by safety check article Conveyer belt transmission speed and the length computation at position that can be displayed in x-ray image of conveyer belt acquire.
In some embodiments, step S11 includes the following steps S111-S114:
S111, obtain the screening machine shooting area length.
The regional scope that the shooting area i.e. X-ray video of screening machine are shown.The shooting area of screening machine has been determined Length, also determined that the actual distance that the shooting area of screening machine is passed through by safety check article.
S112, obtain the screening machine conveyer belt transmission speed.
The transmission speed of conveyer belt is can be pre-set, obtains the transmission speed of conveyer belt, has also just obtained quilt The speed that safety check article passes through the shooting area of screening machine.
S113, the length and the transmission speed are divided by, obtain sampling time reference value.
By the length divided by the transmission speed, the sampling time reference value can be obtained.The sampling time ginseng It examines value and illustrates the time required for the shooting area for passing through screening machine by safety check article.
S114, the sampling time reference value is multiplied with preset constant a, obtains the sampling time interval.
The constant a is greater than 0, and is less than or equal to 1.The sampling time interval is joined less than or equal to the sampling time Examine value.
Reasonable sampling time interval is set according to sampling time reference value, so that same crossing safety check by safety check article Only it is collected an x-ray image during machine, and will not there is a situation where missing inspections.
It, can be automatic after the length of the shooting area for the transmission speed and screening machine for obtaining conveyer belt in the present embodiment Calculate and be arranged the sampling time interval of x-ray image so that the sampling time interval of the x-ray image of this method with by safety check article Movement speed be adapted, save the trouble of manual setting sampling time interval.
Each packing material region in S2, the identification x-ray image, according to each packing material region from the X-ray It is marked off in image and the one-to-one X-ray subgraph of each packing material.
Packing material is for accommodating by safety check article.
Might have in one frame x-ray image multiple passengers by safety check article, each passenger's is usually by safety check article It is placed in respective packing material, screening machine is then to carry out safety check to the article in packing material one by one.When safety check, typically Multiple packing materials cross screening machine successively, therefore may have multiple packing materials in a frame x-ray image.In traditional direct surveillance X In the mode of light video, security staff, which picks out in the packing material of X-ray video, suspicious violated object, then to containing suspicious Violated object packing material carries out out packet confirmation and checks.Security staff is actually to distinguish one by one to the packing material in X-ray video Know.Similarly, the application, which will determine, contains suspicious violated object in the packing material of which passenger, it is necessary to first by each packing material area It separates, whether then identifies respectively in each packing material containing suspicious violated object, when finding that it is suspicious that some packing material is kept When violated object, need to only be further examined to the packing material for keeping suspicious violated object can.
Packing material includes the device that such as tank, basket, bottle, altar, tank, bag are used to accommodate article.It is to be appreciated that certain A little independent articles for crossing screening machines, such as instrument and equipment may accommodate although itself is not put in packing material, inside it Against prohibited cargo, therefore the independent article for crossing screening machine is also considered as packing material.
In some embodiments, as shown in Fig. 2, step S2 includes the following steps S21-S22:
S21, with the gray value of background area in the x-ray image be reference, identify the packing material in the x-ray image Pixel.
Background frame shown by X-ray video be it is fixed, therefore, each pixel of the background area in x-ray image Gray value is also fixed.Background area in x-ray image is different with packing material gray value, therefore the back in x-ray image Scene area and packing material are easy to distinguish.Each pixel of background area in x-ray image is labeled as logical zero, by X-ray figure Belong to each pixel of packing material as in and be labeled as logic 1, to distinguish each pixel of background area and belong to each picture of packing material Vegetarian refreshments.
S22, all pixels point on each packing contour in the x-ray image is identified respectively, according to each packing material All pixels point on profile marks off and each packing material X-ray subgraph correspondingly from the x-ray image.
During crossing screening machine, between the packing material of front and back generally can there are certain intervals, therefore, x-ray image In background area each packing material is separated.The edge placement for finding each packing material and background area, has also just marked off X The region of each packing material in light image to get to the one-to-one X-ray subgraph of each packing material, then to X-ray subgraph In packing material carry out violated object identification.
In some embodiments, step S22 includes the following steps S221-S223:
S221, the first pixel for extracting any packing material not being traversed in the x-ray image at random.
First pixel is any pixel point of packing material.
The method that random walk is used in the application, traverses x-ray image.First in the matrix of x-ray image with Machine obtains the first pixel of any packing material not being traversed, as packing material starting pixels point in traversal x-ray image.From Beginning pixel position starts to traverse each pixel in the packing material being traversed where it.
Each pixel around S222, the traversal starting pixels point;If traversing the upper and lower, left and right of the second pixel There are the pixels of the background area in four adjacent pixels, it is determined that second pixel is on packing contour Pixel;Second pixel is any pixel point around first pixel;Traverse out first pixel All pixels point on the profile of affiliated packing material.
Identify that the pixel in packing material beside a certain pixel whether there is the pixel of background area, and if it exists, then Illustrate the pixel in packing material edge.The pixel in packing material is traversed using which, until traversing packet Filling all directions of object is all background area.
All pixels point area defined figure on the profile of packing material belonging to S223, extraction first pixel Picture, as the corresponding X-ray subgraph of packing material belonging to first pixel.
When traversing all directions of packing material is all background area, also determines that and belonged to the packing material all pixels point Region, also determined that the packing material X-ray subgraph.After a packing material is traversed in x-ray image, return step S221, Other packing materials not being traversed are found, continue to extract the packing material that this is not traversed, until will be each in x-ray image Packing material X-ray subgraph marks off one by one to be come.
S3, target data is extracted from the X-ray subgraph by the convolutional layer of convolutional neural networks model, by described The pond layer of convolutional neural networks model carries out de-redundancy processing to the target data, obtains article characteristics information;It will be described Article characteristics information input is to violated object identification model;By the violated object identification model to the packet in the X-ray subgraph Each in dress object is identified that there are suspicious violated in the packing material in the X-ray subgraph if identifying by safety check article Object then matches corresponding preset violated probability value for each suspicious violated object.
The article characteristics information includes contoured article characteristic information and item color characteristic information etc..
Preset the convolutional neural networks model of 3*3 width, starting picture of the convolutional neural networks model from X-ray subgraph The position of vegetarian refreshments starts, and using 1 pixel as stride, gradually traverses to the data of X-ray subgraph, runs convolution algorithm, Extract the article characteristics information in X-ray subgraph.Article characteristics information is spliced into continuous data by convolutional neural networks model, And by spliced article characteristics information input to violated object identification model.
In some embodiments, the expression formula of violated object identification model are as follows:
Wherein, I is the dimension of input vector, and V is the dimension of the article in the X-ray subgraph Jing Guo vectorization, and H is hidden The neuron number of layer, K are the neuron number of output layer, and x is the object that the convolutional neural networks model extraction comes out Product characteristic information, v are the vector data that the violated object identification model is converted to the article characteristics information recognition result, For the input at hidden layer neuron current time in the violated object identification model,To be implied in the violated object identification model The output at layer neuron current time;For the input at output layer neuron current time in the violated object identification model; For the output at output layer neuron current time in the violated object identification model,For violated probability value.
Violated object identification model is trained in advance.Specifically, a certain amount of training X-ray is acquired from X-ray video Image includes the characteristic information of violated object in trained x-ray image.The violated object in each trained x-ray image is manually marked out, And corresponding violated probability value is distributed for each violated object of mark.The data for carrying out the training x-ray image manually marked are defeated Enter to violated object identification model.Violated object identification model passes through the characteristic information of the violated object marked to trained x-ray image Remembered, remember the weighted value for identifying each characteristic information of each violated object, each violated object is accurately identified to realize, and Export that each violated object is corresponding to preset violated probability value.The model of article has much for identification, can use convolutional Neural net Network and Recognition with Recurrent Neural Network realize that convolutional neural networks extract the article characteristics information in x-ray image, by the object of extraction Product characteristic information is sent to Recognition with Recurrent Neural Network;Recognition with Recurrent Neural Network identification is according to article characteristics information to disobeying in x-ray image Prohibited cargo is identified.The training general principles of identification model are consistent, are not repeated herein.
A possibility that different articles is violated object is different, for example, the water bottle in packing material, only with having water in packing material Bottle is not enough to determine the liquid for having inflammable, explosive in water bottle, but also has a possibility that equipped with inflammable, explosive liquid.It therefore, is doubtful Like the article of water bottle, one corresponding violated probability value is set.It is violated to more accurately judge to whether there is in packing material Object establishes the identification probability list of a variety of violated objects, carries out violated object by the way of to each suspicious violated object allocation probability value Identification.
Violated object is not necessarily certain complete article, is also possible to some position of some complete article.In order to more Accurately judge whether article is violated object, in the violated object identification model of training, a complete article can be divided into Multiple concrete positions, and a corresponding violated probability value is distributed for each position.For example, the bar in packing material is likely to be separated The cutter of taboo, it is also possible to other normal goods, to distribute a corresponding violated probability similar to the bar of violated cutter Value;Violated club can all have the handle object suitable for holding, and be corresponding violated similar to the distribution one of the handle object of violated cutter Probability value;It will be similar to that the corresponding violated probability value of the bar of violated cutter is corresponding with the handle object of violated cutter is similar to Violated probability value be overlapped, obtained probability value can accurately more reflect whether identified integral item is violated Object.To the more specific of the position of article identification, the accuracy rate of identification is higher.
S4, the corresponding violated probability value of each suspicious violated object is overlapped by accumulator, obtains probability value summation.
Accumulator is preset, the corresponding violated probability value of possible violated object each in packing material is carried out by accumulator Summation, obtained probability value summation is higher, illustrates that a possibility that packing material is included against prohibited cargo is bigger.
If S5, the probability value summation are greater than the violated object threshold value, determine in the packing material in the X-ray subgraph There are violated objects.
Very low violated probability value is not enough in accurate judgement packing material that there are violated objects, it is likely to violated object phase As non-violated object carry out identifying obtained violated probability value.Set a violated object threshold value, the probability value summation Just determine to contain in packing material when the sum of each violated probability value is more than preset violated object threshold value with preset violated object threshold value Against prohibited cargo, it can more accurately identify whether packing material contains violated object in this way.
