Because the invention creates a drawing board when the first picture of the current wrapped picture is used for synchronously duplicating the pixel value of the current picture, when the last picture of the current wrapped picture is used, the drawing board is converted into the current drawing board picture which already contains the first picture, the pictures between the first picture and the last picture and the pixel value of the last picture, and all the pictures are deleted; when the picture is rendered, only the picture of the drawing board before the current picture, or the picture of the drawing board before the current picture, the picture before the current picture (at most, all the pictures belonging to the current wrapped picture), or the picture of the drawing board before the current picture, or the picture of the current drawing board. The method comprises the steps that 1 drawing board picture corresponding to one wrapped X-ray picture and at most all column pictures corresponding to the current wrapped X-ray picture are included in a picture through head-to-tail judgment, and particularly all the column pictures of the current wrapped X-ray picture are finally replaced by one drawing board picture, so that the number of rendering objects imaged in each displacement is greatly reduced, and the overhead requirement of a client is greatly reduced.
3. Because the intelligent image recognizing box can provide coordinate information of contraband, when imaging, a contraband identification frame generally needs to be formed in a picture, if a column picture corresponding to each parcel picture (the parcel picture is also generally called as a luggage image) is independently arranged in the picture, a marking frame needs to be built in the corresponding column picture, when rendering is carried out each time, reloading is needed and calculation is carried out again according to the displacement, and the operation burden is greatly increased.

Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited to these examples.
Example 1
As shown in fig. 1-7, the method for scanning and imaging by an X-ray simulator based on column data comprises the following steps:
s1, sequentially obtaining 1 current column data byte group corresponding to one package picture;
s2, converting 1 current column data byte group into 1 current column picture;
s3, judging whether the current column picture is the first column picture of a wrapping 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 values of the current column of pictures into a drawing board g;
s6, rendering and displaying all the drawing board pictures in front of the current row of pictures after integrally moving across the width of one row of pictures, and rendering and displaying the current row of pictures along the edge of the screen S;
s7, judging whether the current column picture is a tail column picture of a wrapping picture, if so, turning to S9, and if not, turning to S8;
s8, rendering and displaying all the drawing board pictures and all the column pictures in front of the current column picture after moving across the width of one column picture, and rendering and displaying the current column picture 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;
and S10, rendering and displaying all the drawing board pictures in front of the current row of pictures after moving across the width of the row of pictures, and rendering and displaying the current drawing board picture g along the edge of the screen S.
As shown in fig. 6, the package image is 1 package image (a row package image or a row package image), a package image does not have a contraband identification frame, the package image is obtained by processing and dividing by an intelligent image recognition box, and only contraband identification information (including a contraband name and identification frame coordinate information) is obtained after identification, the intelligent image recognition box cuts the package image into a plurality of column data byte groups, the column data byte groups are binary, and the column data byte groups are simply referred to as column data and are generally used for facilitating transmission.
As shown in fig. 1, if a plurality of column data corresponding to each parcel picture are transmitted to the imaging terminal, and the imaging terminal performs imaging display column by column, in one screen, in addition to displaying the column picture corresponding to the current parcel picture, the column picture corresponding to the previous parcel picture is also shifted and rendered for display. That is, when the client receives the column data of the package, the column data is usually directly converted into a picture and directly rendered in the package picture display area of the client, and how many columns of data pictures are rendered for how many columns of data. This practice causes the following problems:
1. when the number of the packages in the picture is too large, the number of the displayed pictures is too large, for example: assuming that there are 10 packets, 20 columns of each packet, and a top view angle and a side view angle, respectively, there are 10 × 20 × 2=400 pictures rendered in total, so that 400 pictures are rendered for each step of display at the client, and when there are more columns of data to be received, 400 pictures are moved at the same time, which is very costly to the client.
2. When the contraband identification frame coordinate of the intelligent identification picture is received, the position of the contraband identification frame coordinate needs to be calculated according to the pixel points of the picture, if the contraband identification frame coordinate needs to be calculated according to the column data, the process is very complex, and the relative position of the contraband frame and the column data picture needs to be recalculated every time the package moves.
Aiming at the problems, the invention provides a concept of canvas synchronization, a received column picture is taken, the RGB value of each pixel point is taken, the RGB value (pixel value) is drawn on the drawing board according to the same position, for 1 parcel, after the complete parcel is received, the column picture is not displayed, and the data of the drawing board is converted into the drawing board picture to be rendered and imaged on a client. This saves a lot of performance in picture rendering.
As shown in fig. 3 and 4, or the above example, in the present invention, the first 9 packages all form the corresponding sketchpad pictures g1 and g2 \8230, for the current package, if the current column of pictures is the first column of pictures, the current column of pictures and the first 9 sketchpad pictures are rendered and imaged, i.e., (9 + 1) = 2=20 pictures, if the current column of pictures is not the first column of pictures nor the last column of pictures, i.e., the middle column of pictures, the previous column of pictures, the current column of pictures and the first 9 sketchpad pictures are rendered and imaged, i.e., (9 +1 or 2 or \8230; 18))) 2, if the current column of pictures is the last column of pictures, all the columns of pictures are deleted, the first 9 sketchpad pictures and the current picture are rendered and imaged, i.e., (9 + 1) =2 pictures, and 20 pictures are displayed on the client side and moved. And when the frame is drawn, the coordinates of the contraband identification are calculated according to the width and the height of the drawing board, and the drawing is directly carried out on the drawing board.
The manner of determining the first-column pictures and the last-column pictures is conventional technology, and is not described herein again.
As shown in fig. 3, the picture in the screen S is moved from right to left, after the column data corresponding to the current parcel enters, the column picture 1 is formed, and after the column data is judged to be the first column picture, the picture of the drawing board corresponding to the previous parcel is rendered, the column picture 1 is rendered and displayed on the rightmost side of the screen S, and the pixel value of the column picture 1 is drawn into the drawing board g in the hidden state, and before no column picture is judged to be the last column picture, the drawing board g is used as 1 drawing board container corresponding to the current parcel, and is initialized on the right side of the screen similarly, and is also synchronously traversed.
As shown in fig. 4, after the column data corresponding to the current parcel enters, a column picture 3 is formed, since the column picture 3 is determined not to be the first column picture, the pixel value is written into the drawing board g, and meanwhile, after the column picture 3 is determined to be the last column, the column pictures 1, 2, and 3 corresponding to the current parcel are all deleted, 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, wherein the drawing board is created to be in a state of filling the first column of picture pixels but being hidden, is filled with a plurality of column picture pixels but being hidden, and is in a state of being rendered and displayed after the pixels of all the column pictures of the current package are filled to form a new picture.
Further, when the drawing board g is converted into the current drawing board picture g, the widths of the current column of pictures and all the column of pictures are read and summed to obtain a cutting width, a new drawing board g is obtained according to the cutting width, and the new drawing board g is converted into the current drawing board picture g. The process further defines the boundaries of the final sketchpad picture g, the width of one sketchpad picture g is the same as the width of 1 parcel picture, but it is determined based on the sum of the widths of all column pictures corresponding to one parcel. The merged re-imaging of all columns of a parcel on the display terminal side is achieved, but the dynamic nature of the imaging is preserved.
Further, the method for scan imaging of an imitative X-ray machine based on column data according to claim 1, wherein the current drawing board picture comprises a first column of pictures, column pictures between the first column of pictures and a last column of pictures, and pixel values of the last column of pictures; each drawing board picture before the current list of pictures corresponds to a parcel picture, and the parcel picture is a parcel X-ray picture with a complete outline.
Further, before the drawing board g is converted into a 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 a drawing board g according to coordinate information of the contraband identification frame, generally finding angular points according to the corresponding relation between coordinates and pixel coordinates in the drawing board g, wherein the angular points generally comprise 2 angular points including an upper left angular point and a lower right angular point, forming a frame line based on the 2 angular points, and converting pixel points passed by the frame line into line frame pixels.
Furthermore, the current column of pictures is pictures with fixed height, h and aspect ratio; the drawing board g is a drawing board with a fixed height, h and a width, S, of the screen; the h is the same height as the screen S. Because one parcel picture may come from different X-ray machines, in order to unify the picture size, h is taken according to the height fixation, the aspect ratio is kept to form the current list of pictures, and the proportional relation is used for subsequent calculation after being kept.
Further, the edge of the screen S refers to a side away from which the overall traversing direction deviates, for example, if the overall traversing direction is to the left, the edge of the screen S refers to the rightmost side, and if the overall traversing direction is to the right, the edge of the screen S refers to the leftmost side.
Furthermore, the 1 current column data byte group corresponding to one parcel picture and the contraband identification frame coordinate information corresponding to one parcel picture are both from the intelligent picture recognition box.
