Description

Technical Field

[0001] The present application relates to the technical field of security inspection machine video display, and in particular to a method and device for removing artifacts from security inspection images, a security inspection machine, an electronic device and a medium. Background Art

[0002] When the package enters the security inspection machine, it will trigger the security inspection machine to turn on the X-ray light source equipment. When the package passes through the gap emitted by the X-ray light source at a uniform speed, the different substances in the package absorb and attenuate the X-rays. The X-rays that pass through the package obtain the data of the scanned package through the photodiode array, and the obtained data is processed and converted into image data. Since only one column of data can be obtained each time scanning, the data column obtained from each subsequent scan is spliced ​​to the back of the previous image data column. It only needs to splice the data columns with uniform time intervals to obtain a two-dimensional image of the package under X-rays, and then the obtained two-dimensional package image is displayed on the monitor in a scrolling manner.

[0003] In the related art, the security inspection machine needs to keep the X-ray on all the time in two usage scenarios. One is when there is a large flow of people, such as at a train station during the Spring Festival, the X-ray of the security inspection machine needs to be turned on all the time. The other is when forced scanning is turned on (forcibly turning on the X-ray all the time). In the above two usage scenarios, during the period from when the radiation source is turned on to when it is working stably, the X-ray dose will change as the temperature of the device changes. When the radiation dose changes and bright field correction cannot be performed, artifact problems will occur. At the same time, during the continuous bag passing process of the security inspection machine, the deviation of the belt will also cause artifacts in the imaged image.

[0032] This embodiment provides a method for removing artifacts from security inspection images, which is at least applicable to a security inspection machine for package security inspection, such as an X-ray security inspection machine. Figure 2 FIG. 1 is a flow chart of the method for removing artifacts from security inspection images of this embodiment. Figure 2 As shown, the process includes the following steps:

[0033] Step S201, obtaining a security inspection image to be displayed, wherein the security inspection image is obtained by a security inspection machine continuously scanning a package transmitted into the security inspection machine.

[0034] In this embodiment, the security inspection machine uses an X-ray machine to scan the parcel on the conveyor belt of the security inspection machine, that is, the parcel that has been inspected is irradiated by an X-ray light source, and then the original energy data of the scanned parcel is obtained through the X-ray photodiode array, and then an X-ray scanning line graph is obtained, wherein each scan obtains an X-ray scanning line graph, that is, a frame of original energy data, and the pixel width of the X-ray scanning line graph is usually 1 pixel. Since the conveyor belt carries the parcel and moves relative to the X-ray machine, the X-ray machine can continuously scan and obtain each vertical line image of the parcel, and finally obtain the security inspection image of the entire parcel.

[0035] In this embodiment, the security inspection image may be an X-ray scanning line image, or may be an image obtained by splicing a plurality of X-ray scanning line images scanned in a continuous period of time.

[0036] In this embodiment, the security inspection machine collects a preset number of lines of X-ray scanning line images each time, and repeats the collection of X-ray scanning line images within a preset time interval, and completes the subsequent artifact removal step in the form of the collected scanning line images.

[0037] In this embodiment, a dark field and bright field correction is performed before the security inspection machine is started, and the bright field correction before startup uses preset bright field correction data. After the security inspection image is acquired, that is, when the artifact removal method steps of the present application are implemented, the bright field correction data generated after real-time updating based on the preset bright field correction data is used to perform corresponding bright field correction on the security inspection image, thereby completing the artifact removal processing of the security inspection image.

[0038] In this embodiment, after obtaining a security inspection image, the time when the security inspection image is obtained is verified to determine whether it is a security inspection image for which bright field correction processing is to be performed. After determining that it is a security inspection image that needs bright field correction processing, the timing of performing bright field correction processing on the image is started. Through timing, when the corresponding security inspection image is obtained when the security inspection machine obtains the corresponding security inspection image next time, it is determined whether the bright field correction is completed through the timing duration.

[0039] Step S202, detecting a package in the security inspection image, and determining a corresponding detection result, wherein the detection result includes a first area in the security inspection image where no package is present.

[0040] In this embodiment, the source of the bright field correction data is determined by detecting whether there is a package in the security inspection image and judging the position of the package; in this embodiment, the first area without a package in the security inspection image may be the blank area at both ends of the package, or the area included in the entire security inspection image.

[0041] In this embodiment, the security inspection image for package inspection is the security inspection image corresponding to the current moment; in this embodiment, since the security inspection image can be an X-ray scan line graph or an X-ray scan line graph in multiple continuous times, the original energy data of the current frame can be used for package inspection, or multiple frames of original energy data of the current time period corresponding to the current moment.

[0042] Step S203: Detecting a first scan line graph corresponding to the first area from the first scan line graph data corresponding to the security inspection image, and updating the bright field correction data corresponding to the first area using the first scan line graph.

[0043] In this embodiment, after the first area is determined, the first scan line image corresponding to the first area is obtained from the first scan line image data of the security inspection image to be displayed. For example, when the first area corresponds to the area corresponding to the entire security inspection image, all the first scan line images in the first scan line image data corresponding to the security inspection image to be displayed are obtained; when the first area is the blank area corresponding to the two ends of the package, the first scan line image corresponding to the position of the blank area is obtained.

[0044] In this embodiment, after detecting the first scan line image corresponding to the first area, the corresponding first scan line image is used as new bright field correction data to update the bright field correction data originally corresponding to the security inspection image, that is, the corresponding first scan line image is used as the bright field correction data corresponding to the security inspection image at the current moment.

[0045] Step S204, processing the first scan line graph data by using the updated bright field correction data to generate second scan line graph data corresponding to the security inspection image, and displaying the package image generated by the second scan line graph data.

[0046] In this embodiment, when the X-ray is continuously turned on, bright field correction data from different sources are obtained by judging whether there is a package, and based on the corresponding bright field correction data obtained, bright field correction is performed on the first scanning line image data corresponding to the current security inspection image. The scanning line image data after bright field correction, that is, the second scanning line image data, is processed by a preset data processing method to generate a corresponding package image and perform corresponding display processing.

[0047] In this embodiment, after the corresponding package image is generated according to the second scan line image data, a video packet cutting and segmentation technology is used to segment an image of a preset specification from the generated corresponding image, and then, based on the judgment of whether the image of the preset specification contains a package, the corresponding package image is sent to the display device for display.

[0048] It should be noted that in the examples of the present application, the correction processing of the scan line image data of the security inspection image is described based on the bright field, but in the application scenarios and specific security inspection image display processing corresponding to the embodiments of the present application, the correction of the scan line image data also needs to involve the correction of the dark field, but in the embodiments of the present application, the data processing corresponding to the dark field correction is not elaborated in detail.

[0049] Through the above steps S201 to S204, by acquiring a security inspection image to be displayed; detecting a package in the security inspection image, and determining a corresponding detection result, wherein the detection result includes a first area in the security inspection image where there is no package; detecting a first scan line graph corresponding to the first area from the first scan line graph data corresponding to the security inspection image, and using the first scan line graph to update the bright field correction data corresponding to the first area; processing the first scan line graph data by the updated bright field correction data to generate second scan line graph data corresponding to the security inspection image, and displaying the package image generated by the second scan line graph data, the problem that the X-ray of the security inspection machine is continuously turned on and bright field correction cannot be performed and artifacts are generated is solved, and the beneficial effect of eliminating artifacts caused by ray source attenuation or belt deviation by judging whether there is a package and the package position and then performing bright field correction is achieved when the X-ray of the security inspection machine is continuously turned on.

[0050] The embodiments of the present application are described and illustrated below through preferred embodiments.

[0051] In some of the embodiments, detecting a package in a security inspection image and determining a corresponding detection result are achieved by the following steps:

[0052] Step 1: When a package is detected in a security inspection image, determine the location information of the package in the security inspection image.

[0053] Step 2: According to the position information, a blank area around the package is identified from the security inspection image, wherein the first area includes the blank area around the package.

[0054] In this embodiment, when a package is detected in a security inspection image, the package position is detected at the same time; in a specific embodiment, when the security inspection image includes an X-ray scanning line image, if a package is detected, blank areas at both ends of the package in the X-ray scanning line image where there is no package are identified, and the original energy data corresponding to the blank areas are generated as bright field correction data, and the bright field correction data originally corresponding to the blank areas are replaced according to the generated bright field correction data; when the security inspection image includes multiple X-ray scanning line images, if a package is detected, and the package appears close to the package, the blank areas corresponding to both ends of each X-ray scanning line image are identified, and the original energy data corresponding to each blank area are generated as bright field correction data of each X-ray scanning line image, and the original bright field correction data corresponding to the blank area in each X-ray scanning line image is replaced, that is, the scanning line image (original energy data) in the first scanning line image corresponding to the blank area is used as the corresponding bright field correction data, and the corresponding bright field correction data is used to replace the original bright field correction data at the corresponding position, and the bright field correction of the corresponding position is performed based on the new bright field correction data.

[0055] In the above steps, when a package is detected in the security inspection image, the position information of the package in the security inspection image is determined; based on the position information, a blank area located around the package is identified from the security inspection image, wherein the first area includes the blank area located around the package, thereby determining the selection standard corresponding to the selected bright field correction data based on whether there is a package in the security inspection image and based on the position of the package, that is, determining the first area corresponding to the selected bright field correction data.

[0056] In some embodiments, the first area includes a blank area located around the package, and a first scan line image corresponding to the first area is detected from the first scan line image data corresponding to the security inspection image, and the bright field correction data corresponding to the first area is updated by using the first scan line image. The following steps are implemented:

[0057] Step 1: From the initial bright field correction data corresponding to the security inspection image, first bright field correction data and second bright field correction data are obtained respectively, wherein the initial bright field correction data is the bright field correction data that has been updated before the security inspection image is obtained, the first bright field correction data is the bright field correction data corresponding to the blank area, and the second bright field correction data is the bright field correction data corresponding to the area where the package is located.

[0058] In this embodiment, the first area is first determined, and then the corresponding source of bright field correction data is determined. The bright field correction data is used to update the original bright field correction data in the first area. Before updating the corresponding bright field correction data, it is necessary to determine the bright field correction data to be updated corresponding to the first area in the security inspection image, that is, the first bright field correction data, and determine the existing bright field correction data corresponding to the area where the package is located in the security inspection image, that is, the second bright field correction data. The second bright field correction data is the bright field correction data that does not need to be updated.

[0059] Step 2: Acquire a first scan line graph corresponding to the blank area, and generate first target bright field correction data according to the first scan line graph corresponding to the blank area.

[0060] In this embodiment, after determining the bright field correction data that needs to be updated and does not need to be updated according to the position corresponding to the first area, the corresponding first scan line image is obtained from the first scan line image data of the current security inspection image (the scan line image data that has not undergone this bright field correction) according to the position corresponding to the first area, and the corresponding first target bright field correction data is generated according to the obtained first scan line image. The first target bright field correction data is used to update the bright field correction data that needs to be updated, that is, to update the first bright field correction data; in this embodiment, the first target bright field correction data can be based on a preset data processing method to process the corresponding first scan line image into the first target bright field correction data, and can also be directly using the corresponding first scan line image as the first target bright field correction data.

[0061] Step 3: Replace the first target bright field correction data with the first bright field correction data, and generate updated bright field correction data corresponding to the security inspection image based on the first target bright field correction data and the second bright field correction data.

[0062] In this embodiment, after the bright field correction data in the position area corresponding to the first area is updated, the updated bright field correction data is used as a part of the bright field correction data for performing bright field correction on the current security inspection image, and combined with the second bright field correction data that does not need to be updated, to generate bright field correction data for performing bright field correction on the current security inspection image, and bright field correction is performed on the current security inspection image based on the bright field correction data for performing bright field correction on the current security inspection image.

[0063] Through the above steps, the first bright field correction data and the second bright field correction data are respectively obtained from the initial bright field correction data corresponding to the security inspection image; the first scan line image corresponding to the blank area is obtained, and the first target bright field correction data is generated according to the first scan line image corresponding to the blank area; the first target bright field correction data is replaced with the first bright field correction data, and based on the first target bright field correction data and the second bright field correction data, the updated bright field correction data corresponding to the security inspection image is generated, thereby realizing the updating of the bright field correction data of the package in the security inspection image and the bright field correction of the package.

[0064] In some of the embodiments, an image step is further implemented: when no package is detected in the security inspection image, it is determined that the first area includes the area corresponding to the security inspection image. In this embodiment, when there is no package in the security inspection image, it means that the area space included in the security inspection image corresponds to the first area; in a specific embodiment, when the security inspection image includes an X-ray scanning line image, the original energy data corresponding to the X-ray scanning line image is generated as bright field correction data, and the original bright field correction data of the current security inspection image is replaced according to the generated bright field correction data; when the security inspection image includes multiple X-ray scanning line images, the bright field correction data corresponding to each X-ray scanning line image is generated according to the original energy data corresponding to each X-ray scanning line image, and the generated bright field correction data is replaced with the original bright field correction data in each X-ray scanning line image.

[0065] In the above step, when no package is detected in the security inspection image, it is determined that the first area includes the area corresponding to the security inspection image, and the selection of bright field correction data in the absence of a package is achieved by determining the corresponding first area.

[0066] In some embodiments, the first area includes an area corresponding to the security inspection image, and a first scan line image corresponding to the first area is detected from the first scan line image data corresponding to the security inspection image, and the bright field correction data corresponding to the first area is updated based on the first scan line image by the following steps:

[0067] Step 1: Acquire the initial bright field correction data corresponding to the first scan line image data and the security inspection image, and generate the second target bright field correction data according to the first scan line image data.

[0068] In this embodiment, the second target bright field correction data can be based on a preset data processing method, processing all the first scanning line images corresponding to the security inspection image into the second target bright field correction data, or directly using all the first scanning line images corresponding to the security inspection image as the first target bright field correction data.

[0069] Step 2: Replace the second target bright field correction data with the initial bright field correction data corresponding to the security inspection image to generate updated bright field correction data corresponding to the security inspection image, wherein the updated bright field correction data corresponding to the security inspection image includes the second target bright field correction data.

[0070] In this embodiment, when the second target bright field correction data and the initial bright field correction data corresponding to the security inspection image are replaced to generate updated bright field correction data corresponding to the security inspection image, the corresponding timer for recording the start after the security inspection image is acquired will be reset.

[0071] By acquiring the first scan line image data and the initial bright field correction data corresponding to the security inspection image in the above steps, the second target bright field correction data is generated according to the first scan line image data; the second target bright field correction data and the initial bright field correction data corresponding to the security inspection image are replaced to generate updated bright field correction data corresponding to the security inspection image, wherein the updated bright field correction data corresponding to the security inspection image includes the second target bright field correction data, thereby realizing the update of the bright field correction data without a package in the security inspection image and the bright field correction with a package.

[0072] In some of the embodiments, after obtaining the security inspection image to be displayed, the following steps are further performed:

[0073] Step 1: Calculate the difference between the current time and the time when the security inspection image to be displayed is obtained, and determine whether the difference is greater than the duration threshold.

[0074] Step 2: When it is determined that the difference is greater than the duration threshold, the package is detected in the security inspection image and a corresponding detection result is determined.

[0075] In this embodiment, when it is detected that the time for acquiring the security inspection image to be displayed does not exceed the preset acquisition time interval, that is, the difference is not greater than the duration threshold, it indicates that the currently acquired security inspection image does not need to be corrected by bright field; in this embodiment, no need to perform bright field correction means that at the current moment, the security inspection image is still in; when it exceeds the preset acquisition time interval, it indicates that the currently acquired security inspection image needs to be corrected by bright field.

[0076] By calculating the difference between the current moment and the moment when the security inspection image to be displayed is obtained in the above steps, it is determined whether the difference is greater than the duration threshold; when it is determined that the difference is greater than the duration threshold, the package is detected in the security inspection image, and the corresponding detection result is determined, so as to determine whether to perform bright field correction according to the time when the security inspection image is read.
