Description
Technical Field
The invention relates to the technical field of security inspection and graph judgment, in particular to a method and a device for locally amplifying a column data package picture by using a drawing board and a display.
Background
In the centralized graph judging scene of security check, the whole system comprises: the method comprises the steps of scanning a package to form an X-ray machine of a package X-ray picture, obtaining an intelligent picture recognition box of a contraband identification result in the package X-ray picture, and centralizing a client of a picture judging workstation.
Currently, a client of a centralized graph judging workstation displays a package X-ray image scanned and cut by an X-ray machine on a screen for a graph judging person to further judge and mark contraband in the package X-ray image of the package. The screen obtains picture information each time that is a parcel X-ray picture corresponding to the complete parcel. Such a method creates the following problems: 1. in order to save network bandwidth, URL transmission is adopted in the drawing of the picture, and network loading consumption is caused during drawing, so that delay is caused; 2. the picture display mode is a static tiling mode, so that fatigue is easy to occur when a picture judgment person judges the picture for a long time, and risks such as untimely picture judgment, missed judgment, misjudgment and the like are caused; 3. the original image judging person is a security check value machine, and the image judging person can adapt to a new image judging mode after the post adjustment due to the fact that the scanning imaging video (left-to-right or right-to-left dynamic imaging) of the X-ray machine is observed frequently before, and the training cost is high.
In order to solve the problems, an imaging method based on column data is created, the method is that after a parcel X-ray picture is cut by an intelligent picture identification box and contraband is identified, a continuous video image is cut into a parcel picture, the parcel picture is cut into column data, the column data is sent to a client for picture judgment, the client is imaged, and for the client, all column data corresponding to the parcel picture is imaged on a screen S in sequence, so that the effect of simulating column-by-column scanning imaging is achieved.
If the above-mentioned column data imaging technology is adopted, when a requirement for magnifying viewing, such as a certain prohibited article, needs to be magnified for determining, a magnifying function is generally required to be configured at the client. Generally, for a complete package picture, since the object is 1 picture, the existing technical means of pointing, extracting, amplifying and displaying can be directly used. However, in the column data imaging technology, since a complete package picture is divided into a plurality of column data, and one column data is converted into one column picture for imaging display, when we select an amplifying reference point in any one column picture, then the content of the adjacent column picture cannot be amplified by adopting the technologies of extraction, amplification and display, which results in the loss of an amplifying area, if the adjacent content is to be amplified, a specific algorithm needs to be performed on the adjacent column picture for calculation, and the burden of system calculation overhead is large. Meanwhile, since the column data imaging technology is the simulated scanning mode, all column pictures can move column by column, so that the amplifying datum point is not well locked, the movement is required to be stopped, and the movement is recovered after the amplifying or the cancel of the amplifying.
In view of the above technical drawbacks, the present invention needs to find a magnification method facing the column data imaging technology.

Only dynamic one-by-one column pictures can be seen in order into the screen S. When the user triggers the zoom-in request, the system captures a zoom-in point A of the user on the screen S, the zoom-in point A is mapped on the column picture, and the coordinate of the zoom-in point in the column picture is obtained, at this time, an image extraction range F is created by taking the coordinate as a reference, and as the pixel of the column picture is 1 to be engraved into the drawing board g. The coordinates of each pixel point are thus mutually corresponding in the drawing board g and the column picture. Therefore, the image extraction range F can be directly mapped to the drawing board g, the image data F1 is extracted from the drawing board g, and the image data F1 is amplified to obtain the image data F2, and at this time, the amplified data F2 needs to be reintroduced into one of the amplified drawing boards g for display by the user.

Example 3
As shown in fig. 8 and 9.
A display for wrapping the data with the data by using a drawing board and locally amplifying the data, wherein the display at least comprises the following picture states;
first picture state: rendering and displaying column pictures of one package picture at the edge of the screen S in sequence;
second picture state: after the user triggers an enlargement request on the column picture in the screen S, an enlarged drawing board g appears in the screen S.
The design principle of the invention is as follows: when the screen S imports the column data, the column data (binary) is converted into the column pictures and the column pictures are rendered and displayed, in the process, the column pictures of 1 package picture are sequentially drawn into 1 drawing board g, and at the moment, the whole drawing board is in a hidden state and cannot be seen by a user. Only dynamic one-by-one column pictures can be seen in order into the screen S. When the user triggers the zoom-in request, the system captures a zoom-in point A of the user on the screen S, the zoom-in point A is mapped on the column picture, and the coordinate of the zoom-in point in the column picture is obtained, at this time, an image extraction range F is created by taking the coordinate as a reference, and as the pixel of the column picture is 1 to be engraved into the drawing board g.

The amplifying drawing board g can move freely and is not limited by the amplifying point A, because the coordinate position is locked by the system when the amplifying point A is marked, the subsequent extraction, amplifying and displaying are not dependent on column pictures, but are dependent on the drawing board g, and the drawing board g can simultaneously contain the entered image data which spans multiple columns (the non-entered column pictures cannot be obtained), so that the invention can realize the cross-column amplifying and the locking amplifying without being additionally provided with a complex operation method due to the movement of the column pictures.
What needs to be specifically stated is:
application scenario 1 of the present invention:
as shown in fig. 1, fig. 1 shows that all the wrapping pictures are divided into a plurality of columns of data, then all the columns of pictures are imaged sequentially on the screen S, and the column of the previous wrapping picture is not disappeared and still imaged on the screen S.
The above-described method of magnification of the present invention can also be adapted to a full-column picture imaging scene as in fig. 1. The method includes the steps that a synchronous drawing board g is needed to be created, pixel values of column pictures are sequentially drawn into the drawing board g, namely, in the scene, the drawing board can be divided into a plurality of parcels instead of being divided into 1 drawing board, the drawing board can be divided into 1 drawing board according to the parcels, and the 1 drawing board corresponds to 1 parcel, so that local amplification operation of the method is not affected in any mode. The invention can extract and amplify data based on the drawing board based on the corresponding relation between the column pictures and the drawing board, and creates an independent amplifying drawing board, and the amplifying drawing board is taken as an amplifying window.
Application scenario 2 of the present invention:
as shown in fig. 2-7, the present invention also provides an imaging method that the current parcel picture is imaged column by using a column picture, and the previous parcel picture is imaged by using a drawing board picture, and because in the method, 1 corresponding drawing board g is created under the condition of 1 parcel, the drawing board g corresponds to only 1 parcel. Therefore, the invention can be suitable for amplifying all the column pictures under the current package, and amplifying operation is carried out based on the drawing board g corresponding to the package.
Specifically, the imaging method that the current package picture adopts column-by-column imaging of the column picture and the previous package picture adopts drawing board picture imaging comprises the following steps:
s1, sequentially acquiring 1 current column data byte group corresponding to a package picture;
s2, converting 1 current column data byte group into 1 current column picture;
s3, judging whether the current picture is the first picture of a package picture, if so, turning to S4, S5 and S6, and if not, turning to S5 and S7;
s4, creating a drawing board g in a hidden state;
s5, drawing the pixel value of the current column of pictures into a drawing board g;
s6, performing rendering display after all drawing board pictures in front of the current column picture wholly transversely move by one column picture width, and performing rendering display on the current column picture along the edge of the screen S;
s7, judging whether the current column picture is a tail column picture of the package picture, if so, turning to S9, and if not, turning to S8;
s8, rendering and displaying all drawing board pictures and all column pictures before the current column picture after the current column picture is integrally transversely moved by one column picture width, wherein the current column picture is rendered and displayed along the edge of the screen S;
s9, converting the drawing board g into a current drawing board picture g, deleting all column pictures, and converting to S10;
s10, rendering and displaying all drawing board pictures before the current column picture after the current column picture wholly transversely moves by one column picture width, and rendering and displaying the current drawing board picture g along the edge of the screen S.
As shown in fig. 6, 1 package picture (line package picture or line package image), one package picture has no contraband identification frame, the package picture is processed and divided by an intelligent picture identification box, only the identification is performed to obtain contraband identification information (including a contraband name and identification frame coordinate information), the intelligent picture identification box cuts the package picture into a plurality of column data tuples, the column data tuples are binary, and the column data tuples are simply referred to as column data, and are generally used for convenient transmission.
As shown in fig. 1, if a plurality of column data corresponding to each package picture is transmitted to the imaging terminal, the imaging terminal performs column-by-column imaging display, and in one picture, besides displaying the column picture corresponding to the current package picture, the column picture corresponding to the previous package picture is rendered for display after being shifted together. When the client receives the column data of the package, the column data is usually converted into the picture to be directly rendered in the package picture display area of the client, and the column data is the number of column data to be rendered. This approach creates the following problems:
1. when there are too many packages in the picture, there are too many pictures displayed, for example: assuming that there are 10 packages, each of which has 20 columns and a look-down angle and a look-up angle, respectively, the total rendered pictures will have 10x20x 2=400, so that the client will render 400 pictures once every step display, and when there are more columns of data to receive, the client will move 400 pictures at the same time, and the performance overhead for the client is very large.
2. When the contraband identification frame coordinates of the intelligent identification map are received, the position of the contraband identification frame coordinates are needed to be calculated according to the pixel points of the picture, if the contraband identification frame coordinates are calculated according to the column data, the process is very complex, and the relative positions of the contraband frame and the column data picture are needed to be recalculated every time the package moves.
Aiming at the problems, the invention provides a canvas synchronization concept, a received column picture is taken to obtain RGB values of each pixel point, the RGB values (pixel values) are drawn on a drawing board according to the same position, and for 1 package, after the complete package is received, the column picture is not displayed any more, and the data of the drawing board is converted into the drawing board picture to be rendered and imaged on a client. Thus saving the performance of rendering a large number of pictures.
As shown in fig. 3, fig. 4, and the above example, in the present invention, the first 9 packages form the corresponding drawing board pictures g1 and g2 …, for the current package, if the current column picture is the first column picture, the current column picture and the first 9 drawing board pictures are rendered and imaged, i.e., (9+1) =20 pictures, if the current column picture is not the first column picture and is not the last column picture, i.e., the middle column picture, the first column picture, the current column picture and the first 9 drawing board pictures are rendered and imaged, i.e., (9+1+ (1 or 2 or …)) 2, and if the current column picture is the last column picture, all the column pictures are deleted, the first 9 drawing board pictures and the current drawing board picture are rendered and imaged, i.e., (9+1) =20 pictures, and only 20 pictures are displayed on the client and moved. And when drawing the frame, calculating the coordinates of the contraband mark according to the width and the height of the drawing board, and directly drawing the frame on the drawing board.
The mode of determining the first-column picture and the last-column picture is a conventional technology, and will not be described in detail here.
As shown in fig. 3, the frame in the screen S moves from right to left, after the column data corresponding to the current package enters, a column picture 1 is formed, and is determined to be the first column picture, at this time, the picture board picture corresponding to the previous package is rendered, and meanwhile, the column picture 1 is rendered and displayed on the rightmost side of the screen S, and meanwhile, the pixel value of the column picture 1 is drawn into a hidden picture board g, and before no column picture is determined to be the last column picture, the picture board g is taken as 1 picture board container corresponding to the current package, and the picture board is initialized on the right side of the screen, and synchronously traverses.
As shown in fig. 4, after the column data corresponding to the current package enters, a column picture 3 is formed, and the pixel value of the column picture 3 is written into the drawing board g because the column picture 3 is determined not to be the first column picture, and after the column data is determined to be the last column, the column pictures 1, 2 and 3 corresponding to the current package are deleted, and at this time, the drawing board g is converted into the drawing board picture g and rendered together with the previous drawing board picture. In the invention, the drawing board has three states, namely, a state of filling first-column picture pixels but being hidden is created, a state of filling a plurality of column picture pixels but being hidden is created, and the pixels of all column pictures filled with current packages form a new picture and are rendered and displayed.
Further, when converting the drawing board g into the current drawing board picture g, reading the widths of the current column picture and all column pictures, summing to obtain a trimming width, obtaining a new drawing board g according to the trimming width, and converting the new drawing board g into the current drawing board picture g. The process further defines the boundaries of the final palette picture g, one palette picture g having the same width as the 1 parcel picture, but determined based on the sum of the widths of all the column pictures to which one parcel corresponds. The combined re-imaging of all columns of a package on the display terminal side is achieved, but the dynamic characteristics of the imaging are preserved.
Further, the method for locally amplifying a column data wrapped picture with a drawing board according to claim 1, wherein the current drawing board picture comprises a first column picture, a column picture between the first column picture and a tail column picture, and pixel values of the tail column picture; each drawing board picture before the current column picture corresponds to a parcel picture, and the parcel picture is a parcel X-ray picture with a complete outline.
Further, before converting the drawing board g into the drawing board picture, the method further comprises the following steps:
s01, acquiring coordinate information of a contraband identification frame corresponding to a package picture;
s02, drawing a corresponding contraband identification frame in the drawing board g according to coordinate information of the contraband identification frame, wherein the drawing of the corresponding contraband identification frame in the drawing board g generally finds out corner points according to a corresponding relation between coordinates and pixel coordinates, generally has 2 corner points at the upper left and lower right, forms a frame line based on the 2 corner points, and converts pixel points through which the frame line passes into line frame pixels.
Further, the current column of pictures is a picture with h fixed in height and the aspect ratio maintained; the drawing board g is a drawing board with a height fixed h and a width of a screen S; the h is the same as the height of the screen S. Because a package picture may come from different X-ray machines, in order to unify the picture size, h is taken with a high degree of fixation, the aspect ratio is kept to form the current column picture, and the proportion relation is reserved and then used for subsequent calculation.
Further, the edge of the screen S refers to the side away from the overall traversing direction, for example, if the overall traversing direction is leftward, the edge of the screen S refers to the rightmost side, and if the overall traversing direction is rightward, the edge of the screen S refers to the leftmost side.
Further, the 1 current column data byte group corresponding to one package picture and the coordinate information of the contraband identification frame corresponding to one package picture are both from the intelligent picture identification box.
As shown in fig. 1-7, the device for imaging the current parcel picture column by using a column picture and imaging the previous parcel picture by using a drawing board picture comprises:
a screen S;
a memory;
one or more processors; a kind of electronic device with high-pressure air-conditioning system
