[0039] In this embodiment, an image display method is provided for displaying package images of a security inspection machine. Figure 2 is a flow chart of the image display method of this embodiment, such as Figure 2 As shown, the process includes the following steps:

[0040] Step S210: vertical slices of the image of the package acquired in real time are sequentially displayed horizontally in the display area.

[0041] The display area may be any display screen of an electronic display, and the display area is used to display the image data of the package entering the security inspection machine, so that the security inspector can check the information of the items inside the package, thereby determining whether there are prohibited items inside the package. The image data of the package may be the X-ray energy data of the package obtained by scanning the package with X-rays inside the security inspection machine, and then the image data inside the package obtained by conversion. Furthermore, in the actual scenario of security inspection of the package, multiple packages can be sequentially passed through the entrance of the security inspection machine through a conveyor belt and sent into the security inspection machine for inspection. The image data inside the package is mainly obtained by converting the X-ray energy data of the package received by the receiving plate of the security inspection machine, and the security inspection machine can be installed on the conveyor belt to realize the inspection of the package therein. Therefore, in order to increase the residence time of the image data of each package in the display area, the image data of the package collected by the security inspection machine can be divided into uniform image vertical slices according to one or more columns of pixels, and then displayed horizontally in the display area.

[0042] Specifically, the width of the receiving board can be set to the height of the vertical slice of the image, and after the package enters the security inspection machine and the energy data is detected by the receiving board, the image data corresponding to the preset number of column energy data received by the receiving board is used as a vertical slice of the image, that is, the width of a vertical slice of the image can be the width of one or more pixels. In addition, the display mode of the vertical slice of the image in the display area is determined by the moving direction of the package relative to the security inspection machine. According to the moving direction of the package relative to the security inspection machine, the position of the vertical slice of the image in the display area is specifically set to be displayed side by side in sequence. Among them, the vertical slices of the image belonging to the same package can be displayed adjacently in the display area in the order of collection. In addition, the vertical slice of the image is fixedly displayed at a certain position in the display area. When all the vertical slices of the image of the package are displayed adjacently in the display area, the image data of the package is relatively static in the display area, so that the image data blur caused by the movement of the package can be avoided, which causes visual fatigue to the security inspectors.

[0043] In addition, in order to increase the residence time of the packaged image data in the display area, the display area can also be partitioned. For example, when the height of the display area is sufficient relative to the height of the vertical slice of the image, the display area can be partitioned in the vertical direction. Specifically, the display area can be divided into two even upper and lower parts, three upper, middle and lower parts, or other more parts according to the height of the display area. After the display area is partitioned, the display rules of the vertical slices of the image in the partitions of the display area can be set according to the visual laws and visual habits of the security personnel. For example, after the display area is divided into the upper half screen and the lower half screen, the vertical slices of the image can be displayed horizontally in the upper half screen in sequence, and after the upper half screen is fully occupied, the lower half screen is selected for display. It can be understood that other display rules can also be selected to display the vertical slices of the image in different partitions of the display area, which is not specifically limited here.

[0044] Step S220: When the display area is completely occupied and a new vertical image slice needs to be displayed, the new vertical image slice is used to cover the vertical image slice with the longest display time in the picture.

[0045] Since the size of the display area is limited, and the image vertical slices can be continuously generated according to the new packages entering the security inspection machine during the security inspection process, when there are new image vertical slices to be displayed, it is necessary to select the displayed image vertical slices in the display area to cover them. Specifically, in order to increase the display time of the image vertical slices in the display area, the display time of all the displayed image vertical slices in the display area can be compared, and the image vertical slice with the longest display time can be selected and covered with the new image vertical slice, so that the new image vertical slice can be displayed in the display area.

[0046] Furthermore, in order to improve the continuity of the image data of the package in the display area, when the display area is fully occupied, one or more image vertical slices of the package can be selected from the displayed image vertical slices according to the display time of the package in the display area to cover, so as to display all the image vertical slices of the package to which the new image vertical slice belongs. Wherein, when the display area is partitioned, after all the partitions in the display area are occupied in turn, the image vertical slices can be selected to cover in turn starting from the partition to which the image vertical slice with the longest display time belongs, so as to realize the cyclic display of different image vertical slices in different partitions along with the new corresponding image data generated in the security inspection machine. For example, when the upper half screen and the lower half screen of the display area are fully occupied successively, one or more packages with the longest display time can be selected in turn from the upper half screen and covered with the new image vertical slice, and after all the image vertical slices in the upper half screen are updated, one or more packages with the longest display time can be selected in turn from the lower half screen and covered with the new image vertical slice.

[0047] Therefore, the time a package stays in the display area is determined by the occupied state of the display area. If the display area is not completely occupied, the package can continue to be displayed horizontally in the display area. Compared with the related art that sequentially displays the stay time of each package in the moving package screen in the display area, the time each package stays in the display area in this embodiment is longer, so that the item information of each package can be displayed more clearly and accurately, and the visual fatigue of the security inspectors is further alleviated.

[0048] In the above steps S210 to S220, the vertical slices of the image of the package acquired in real time are sequentially displayed horizontally in the display area. When the display area is completely occupied and there are new vertical slices of the image to be displayed, the new vertical slice of the image is used to cover the vertical slice of the image with the longest display time in the screen. This realizes the display of the package staying in the display area, and realizes the replacement of the vertical slices of the image in the display area based on the display time, thereby increasing the time that the image data of the package stays in the display area, and can provide clear and accurate image data for security personnel.

[0049] Further, in one embodiment, based on the above step S210, in the display area, the vertical slices of the image of the package acquired in real time are sequentially displayed horizontally, which specifically includes the following steps:

[0050] Step S211, when the package moves from left to right, the vertical slices of the image acquired in real time are displayed in sequence on the right in the display area.

[0051] Specifically, when the package moves from left to right, the images are vertically allocated and displayed on the right side of the display area in sequence according to the order of the image vertical slices acquired in real time. For example, when the display area is empty, the first image vertical slice acquired first can be displayed on the rightmost side of the display area. When the display area is not empty, the newly acquired image vertical slice can be displayed at the adjacent position to the left of the image vertical slice already displayed in the display area.

[0052] Step S212, when the package moves from right to left, the vertical slices of the image acquired in real time are displayed sequentially on the left in the display area.

[0053] Likewise, when the package moves from right to left, the packages acquired in real time may be displayed horizontally in sequence on the right side of the display area. Figure 3 It is a schematic diagram of the vertical slices of the target package image in the display area when the target package moves from right to left. Figure 3As shown, the target package includes image vertical slices 301, 302, 303, 304, 305 and 306, wherein the image vertical slices 301 and 302 are displayed on the leftmost side of the upper half of the display area. When the security inspection machine sequentially obtains the six image vertical slices of the target package, the six image vertical slices can be horizontally displayed sequentially on the left side of the display area 32 in the order of acquisition, as shown by the direction of the arrows connecting the image vertical slices 303 to 306. Since the image contents on adjacent image vertical slices are continuous, after all the image vertical slices of the package are displayed in the display area, static and continuous image data relative to the display area can be provided to the security inspector.

[0054] In the above steps S211 to S212, by determining the display mode of the vertical slices of the image in the display area according to the moving direction of the package, the continuity of the image data can be improved while providing the security inspectors with image data that conforms to the visual law.

[0055] In addition, in one embodiment, the display area includes two parts, namely, the upper half screen and the lower half screen. Dividing the display area into the upper half screen and the lower half screen can, on the one hand, improve the utilization rate of the display area, and display more vertical slices of images in one display area, so as to adapt to the actual application scenario with a large number of packages; on the other hand, it can also increase the display time of the image information of each package in the display area, thereby providing sufficient time for the security personnel to view the information of the items inside the package through the display area, thereby improving the accuracy of the item detection of the package.

[0056] In addition, the display area can be divided into zones according to specific application scenarios, such as the display screen size of the security inspection machine. The more zones the display area has, the longer the vertical slice display time of the package image will be, but the screen of each zone is relatively small, which is not convenient for security inspectors to observe. Preferably, the display area can be divided into upper and lower parts, which can extend the package display time while ensuring the clarity of human eye observation.

[0057] Further, in one embodiment, based on the above step S210, in the display area, the vertical slices of the image of the package acquired in real time are sequentially displayed horizontally, and the following steps may also be included:

[0058] Step S213, if the upper half of the screen is completely occupied and there are still vertical slices of the image to be displayed, the package to which the vertical slice of the image to be displayed belongs is used as the package to be displayed, and all the vertical slices of the image in the package to be displayed are displayed horizontally in the lower half of the screen.

[0059] Among them, when the display area is divided into the upper half screen and the lower half screen, the image vertical slices can be displayed preferentially in the upper half screen according to the visual rules. Specifically, when the package moves from left to right, the image vertical slices can be displayed in sequence on the left side of the upper half screen. When the upper half screen is fully occupied and there are image vertical slices to be displayed, the image vertical slices to be displayed can belong to the same package as some of the image vertical slices that have been displayed in the upper half screen, or can be a package that is not displayed in the upper half screen. In this case, the package to which the image vertical slice to be displayed belongs can be used as the package to be displayed, and all the image vertical slices of the package to be displayed can be displayed in the lower half screen. Figure 4 is a schematic diagram of displaying vertical slices of a wrapped image in this embodiment, such as Figure 4 As shown, when the package moves from right to left, the image vertical slices of packages 401 to 403 acquired in real time are sequentially displayed on the left side of the upper half screen. When the image data of package 404 exceeds the display boundary of the display area, the vertical slices of the image of package 404 that have been displayed on the upper half screen are moved to the left side of the lower half screen for horizontal display, and the remaining image vertical slices of package 404 that are not displayed continue to be sequentially displayed on the lower half screen.

[0060] Specifically, if some of the image vertical slices in the package to be displayed are already displayed in the upper half of the screen, the image vertical slices in the package to be displayed that are already displayed in the upper half of the screen can be first moved to the lower half of the screen. Further, according to the moving direction of the package, the image vertical slices that have been displayed in the upper half of the screen can be moved to the left or right of the lower half of the screen for display in the order of display in the upper half of the screen. In addition, if there are no image vertical slices that have been displayed in the upper half of the screen in the package to be displayed, the image vertical slices of the package to be displayed can be directly displayed horizontally in the lower half of the screen in sequence.

[0061] In addition, in one embodiment, based on the above step S220, when the display area is completely occupied and a new vertical image slice needs to be displayed, the vertical image slice with the longest display time in the screen is covered with the new vertical image slice, which specifically includes the following steps:

[0062] Step S221, when the lower half screen is completely occupied while the vertical image slices are displayed horizontally in sequence, the occupied area of ​​the vertical image slice with the longest display time is determined in the upper half screen as the target coverage area.

[0063] Step S222: clear the image vertical slice on the target coverage area, and horizontally display all the image vertical slices of the package to which the new image vertical slice belongs on the target coverage area.

[0064] Specifically, according to the size of the area occupied by all the image vertical slices of the package to which the new image vertical slice belongs, the image vertical slices of one or more packages on the target coverage area are cleared to horizontally display all the image vertical slices of the package to which the new image vertical slice belongs on the target coverage area. Figure 5 As shown, when the upper half of the screen is occupied by other packages and package 503, and the lower half of the screen is occupied by packages 504 to 507, and there is a package 508 to be displayed, the vertical image slices corresponding to the other packages in the upper half of the screen can be cleared, so that all the vertical image slices of package 508 can be moved to the area occupied by the other packages for display, wherein the area occupied by package 508 can be the area occupied by one or more other packages.

[0065] In the above steps S221 to S222, when the lower half of the screen is fully occupied, the occupied area of ​​the image vertical slice of the package with the longest display time is determined in the upper half of the screen as the target coverage area, and the image vertical slices on the target coverage area are cleared, so that all the image vertical slices of the package to which the new image vertical slice belongs are displayed on the target coverage area, thereby increasing the display time of the image vertical slices of the package on the display area.

[0066] Additionally, in one embodiment, the vertical slice of the image of the package acquired in real time is at least one column of image data of the package acquired in real time from the X-ray receiving plate.

[0067] In the above steps S210 to S222, when the package moves from left to right, the image vertical slices acquired in real time are displayed sequentially on the right in the display area, and when the package moves from right to left, the image vertical slices acquired in real time are displayed sequentially on the left in the display area, thereby improving the continuity of the image data of the package; the display area is divided into the upper half screen and the lower half screen, thereby improving the utilization rate of the display area for the image vertical slices and increasing the display time of the image vertical slices in the display area; when the display area is fully occupied and there are new image vertical slices to be displayed, all image vertical slices of the package to which the new image vertical slice belongs are used to cover all image vertical slices in the target coverage area, thereby completing the update of the image data of the package in the display area, and increasing the time for each package to display the image data in the display area, thereby providing clear and accurate image data for security inspectors and alleviating their visual fatigue.

[0068] This embodiment also provides an X-ray package vertical slice display method. Figure 6 is a flow chart of the method, such as Figure 6 As shown, the process includes the following steps:

[0069] Step S610, start packet passing;

[0070] Step S620, collecting X-ray package vertical slices;

[0071] Step S630, displaying the vertical slice on the left or right side of one half screen of the display area;

[0072] Step S640, displaying other vertical slices in sequence in the horizontal direction of the half screen;

[0073] Step S650, determining whether there is a new vertical slice that exceeds the display boundary of the display area, if so, executing step S660, otherwise executing step S640;

[0074] Step S660, determining whether there is a remaining area in the other half of the display area, if yes, executing step S670, otherwise executing step S680;

[0075] Step S670, moving the new vertical slice to the other half of the screen for display;

[0076] Step S680, clear all vertical slices of the package with the longest display time in the other half screen, and execute step S670.

[0077] In this embodiment, an image display device is also provided, which is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated.

[0097] In some embodiments, when the processor executes the computer program, the processor further implements the following steps:

[0098] If the entire upper half of the screen is occupied and there are still vertical slices of images to be displayed, the package to which the vertical slices of the images to be displayed belong is used as the package to be displayed, and all the vertical slices of the images in the package to be displayed are displayed horizontally in the lower half of the screen.

[0099] In some embodiments, when the processor executes the computer program, the processor further implements the following steps:

[0100] In the process of horizontally displaying the vertical slices of the image in the lower half screen in sequence, if the lower half screen is completely occupied, then the occupied area of ​​the vertical slice of the image with the longest display time is determined in the upper half screen as the target coverage area;

[0101] The image vertical slice on the target coverage area is cleared, and all the image vertical slices of the package to which the new image vertical slice belongs are horizontally displayed on the target coverage area.

[0102] In some embodiments, the vertical slices of the image of the package acquired in real time are at least one column of image data of the package collected in real time from the X-ray receiving plate.
