It should also be understood that terms defined in a general dictionary, for example, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0049] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be regarded as part of the specification.

[0050] In some related arts, after a visual inspector magnifies an image, the magnified image is moved while being recognized to perform visual inspection work.

[0051] It has been found through research that after the image is magnified, the visual inspector is likely to overlook the area displayed outside the current view window, resulting in missed inspections, reducing the inspection accuracy rate, and may also repeatedly inspect overlapping areas during the movement process, affecting the inspection efficiency.

[0052] In view of this, embodiments of the present disclosure provide an image processing method, an image inspection device, and a radiation image inspection system, which can optimize the inspection effect of the image of the object to be inspected.

[0053] Figure 1 It is a schematic flowchart according to some embodiments of the image processing method of the present disclosure.

[0054] Refer to Figure 1 , embodiments of the present disclosure provide an image processing method, including: step S1 and step S2. In step S1, in response to an inspection operation on the image of the object to be inspected, a browsing window 2 and a global window 1 of the image of the object to be inspected are provided, where the browsing window 2 can display different parts of the image of the object to be inspected according to an input view transformation operation, and the global window 1 can display the whole of the image of the object to be inspected. In step S2, according to the view transformation operation and the duration of maintaining the view transformation state, image processing is performed on the partial image corresponding to the local area displayed in the browsing window 2 in the global window 1 to prominently display the partial image in the global window 1.

[0055] The object to be inspected can be a container, a vehicle, a mineral, or an organism, etc., according to different scenarios. The image of the object to be inspected can be an image for viewing the internal structure or surface structure of the object to be inspected, and is used to display the internal features or surface features of the object to be inspected. The image of the object to be inspected can be, for example, an X-ray image, a backscatter image, a millimeter wave image, etc.

[0056] For example, in security inspection scenarios such as at customs, the contents of a container or vehicle can be inspected for dangerous or prohibited items by examining the image of the object being inspected. In the scenario of mineral inspection, information such as the type or quality of the mineral can be viewed through the image of the object being inspected. In the field of medical image analysis, information such as the location of a lesion can be viewed through the image of the object being inspected.

[0057] The inspection operation is an operation that can indicate that the relevant person inspecting the image of the object being inspected has started to inspect the image of the object being inspected. For example, the inspection operation can be an operation to open the image of the object being inspected, or an operation to open the image inspection module or image inspection function.

[0058] Figure 2 It is a schematic diagram of the browsing window and the global window in the embodiment of the image processing method according to the present disclosure.

[0059] Reference Figure 2 , the browsing window 2 can display the image of the object being inspected and can be able to display different parts of the image of the object being inspected according to the input view transformation operation, for the relevant person inspecting the image of the object being inspected to inspect different positions of the image of the object being inspected.

[0060] The view transformation operation can be to adjust the position, shape and orientation of the image of the object being inspected in the two-dimensional space through geometric transformation to adapt to different display requirements or perspective effects. The view transformation operation can include operations such as zooming, panning or rotating the browsing window 2, so as to adjust the image of the object being inspected within the browsing window 2 to a state conducive to observation.

[0061] Optionally, parameter adjustment operations can be performed on the browsing window 2. For example, operations such as contrast adjustment and brightness adjustment can be performed on the browsing window 2 to allow the relevant person inspecting the image of the object being inspected to more clearly inspect the image of the object being inspected.

[0062] The global window 1 can display the entire image of the object being inspected. Optionally, the local area displayed by the browsing window 2 can be displayed in real time in the global window 1. For example, the corresponding partial image of the local area displayed by the browsing window 1 can be marked with a frame or other form in the global window 1, so that the relevant person can obtain the position of the currently displayed area in the entire image, such as Figure 5 shown.

[0063] The positional relationship between the global window 1 and the browsing window 2 can be as Figure 2 shown. The browsing window 2 can be located at the main position of the display interface, allowing the relevant person to focus on the details of the image of the object being inspected. The global window 1 can be located at the edge position of the display interface, allowing the relevant person to know the position of the corresponding partial image of the local area displayed by the browsing window 2 in the overall image, so as to obtain a sense of spatial orientation.

[0064] The global window 1 and the browsing window 2 can be displayed simultaneously in the same display interface, or each can be in an independent display interface. Optionally, the position of the global window 1 can be adjusted according to the working habits of the relevant personnel who check the image of the object to be inspected. For example, the global window 1 can also be in the form of a separate floating window.

[0065] In step S2, the duration of maintaining the view transformation state can refer to the duration after the view transformation operation ends, during which the display range of the browsing window 2 remains unchanged. In other words, the duration of maintaining the view transformation state can be the duration from the end of the previous view transformation operation to the input of the next view transformation operation. That is to say, the duration of maintaining the view transformation state represents the duration after the view transformation operation ends, during which the relevant personnel keep the view transformation operation uninput and view the display range of the current browsing window 2.

[0066] Performing image processing on a partial image can refer to highlighting the partial image, including but not limited to adjusting the hue, brightness, saturation, transparency, etc. of the image, making the partial image subjected to image processing more prominent, so that the relevant personnel who check the image of the object to be inspected can determine the inspected and uninspected image areas according to the global window 1 after the image processing.

[0067] The embodiments of the present disclosure can perform image processing on the partial image corresponding to the local area displayed in the browsing window 2 in the global window 1 of the image of the object to be inspected according to the view transformation operation of the browsing window 2 of the image of the object to be inspected and the duration of maintaining the view transformation state, which is beneficial for the relevant personnel who check the image of the object to be inspected to notice the inspected and uninspected areas, so as to prompt and assist the relevant personnel in the process of reviewing the image of the object to be inspected. On the one hand, the relevant personnel can quickly move out of the inspected area according to the result of the image processing and conduct the inspection work on the new area, reducing the repeated image judgment work, thereby improving the work efficiency. On the other hand, the relevant personnel can timely discover the uninspected area and conduct the inspection on it, thereby reducing the possibility of missed inspection. The relevant personnel can also recheck the concerned area according to the information of the inspected area, thereby improving the accuracy of the inspection.

[0068] In some embodiments, the image of the object to be inspected is a radiation image of the object to be inspected. A radiation image refers to a visual two-dimensional or three-dimensional image of the internal structure of the object to be inspected generated by using radiation (such as X-rays, γ-rays, etc.) to penetrate the object and then receiving and converting the signals by a detector. The radiation image can display information such as the density distribution, shape, and material of the object to be inspected inside. In the scenario of customs security inspection, the radiation image is mainly used for non-invasive inspection of objects to be inspected such as containers, vehicles, and luggage to identify prohibited items, dangerous goods, or illegal stowaways.

[0069] Figure 3It is a schematic diagram of the specific process of image processing in the embodiment of the image processing method according to the present disclosure.

[0070] In some embodiments, it can be achieved through Figure 3 The steps S21 and S22 shown to perform image processing on the partial image corresponding to the local area displayed in the browsing window 2 in the global window 1 according to the view transformation operation and the duration of maintaining the view transformation state.

[0071] Refer to Figure 3 , in some embodiments, in step S2, performing image processing on the partial image corresponding to the local area displayed in the browsing window 2 in the global window 1 according to the view transformation operation and the duration of maintaining the view transformation state includes step S21 and step S22. In step S21, obtain the zoom ratio of the browsing window 2. In step S22, in response to the zoom ratio being not less than a preset ratio, execute the function of the key attention area.

[0072] Regarding the zoom ratio, when the relevant person checking the image of the object to be inspected performs a zoom-in operation on the image, it usually means that they intentionally focus on the enlarged area. In some embodiments, the preset ratio is not less than 100%, such as 100%, 120%, 150%, etc. When the zoom ratio is greater than 100%, it means that the relevant person is focusing on the enlarged area.

[0073] In some embodiments, the preset ratio is not less than 120% so that the execution of the function of the key attention area matches the action of the relevant person's key attention, thereby reducing the interference of the partial images that are not key attention and not easily missing the partial images of key attention.

[0074] Figure 4 It is a schematic diagram of the process of the function of the key attention area in the embodiment of the image processing method according to the present disclosure.

[0075] Refer to Figure 4 , the function of the key attention area includes step S221 and step S222. In step S221, time the duration of maintaining the current view transformation state of the browsing window 2. In step S222, in response to the duration of maintaining the view transformation state of the browsing window 2 reaching a preset duration, perform image processing on the partial image corresponding to the local area displayed in the browsing window 2 in the global window 1.

[0076] The preset duration can be reasonably set according to the usage scenario. If the preset duration is too long, it may result in the failure to perform image processing on the inspected area. If the preset duration is too short, it may easily cause image processing on the uninspected area due to misoperation. For example, in the scenario of the customs conducting security inspections on containers, the stacking and arrangement of the items inside the container are relatively complex, which is likely to cause image occlusion and overlap. The preset duration can be 5 seconds, 4 seconds, 3 seconds, etc. When the external or internal structure of the inspected object is more complex or simpler, the preset duration is not limited to the above example durations and can be set longer or shorter, such as greater than 5 seconds or less than 3 seconds. For example, in the X-ray inspection software, the implementation method of timing the duration of maintaining the current view transformation state of the browsing window 2 can be to integrate the dwell time function into the X-ray inspection software.

[0077] In some embodiments, the view transformation operation includes at least one of zooming, panning, or rotating the browsing window 2. Separate zooming, panning, or rotating operations can be performed on the browsing window 2. In addition, multiple view transformation operations can be performed simultaneously. For example, an operation of zooming while panning, and the cases of other combinations of multiple view transformation operations will not be elaborated here. In this way, the relevant personnel inspecting the image of the inspected object can flexibly adjust the image of the inspected object to meet different inspection requirements.

[0078] In some embodiments, in step S2, performing image processing on the partial image corresponding to the local area displayed in the browsing window 2 in the global window 1 according to the view transformation operation and the duration of maintaining the view transformation state further includes: in response to a new view transformation operation before the duration of maintaining the view transformation state of the browsing window 2 reaches the preset duration, re-executing or canceling the key attention area function.

[0079] The execution entity for re-executing or canceling the key attention area function can be other functions or modules independent of the key attention area function, which can continuously obtain the timing information of the duration of maintaining the current view transformation state of the browsing window 2 and the information of the input new view transformation operation, and re-execute or cancel the key attention area function based on this information.

[0080] To determine whether to re - execute or cancel the function of the area of key interest, in some embodiments, the steps of re - executing or canceling the function of the area of key interest include: if the zoom ratio of the browsing window after a new view transformation operation is not less than a preset ratio, then re - execute the function of the area of key interest; otherwise, cancel the function of the area of key interest. Re - executing the function of the area of key interest means that the timing of maintaining the current view transformation state of the browsing window 2 before the new view transformation operation will be reset, and a new timing will be started. In this way, it can be confirmed through the new view transformation operation that the relevant person viewing the image of the object under inspection has ended the key - attention action on the local area displayed in the current browsing window 2, so as to reset the timing in a timely manner.

[0081] Reducing the zoom ratio of the browsing window so that the zoom ratio of the browsing window is less than the preset ratio will cause the function of the area of key interest to be canceled. Until the zoom ratio of the browsing window is not less than the preset ratio, the function of the area of key interest is re - executed. In this way, when the relevant person checking the image of the object under inspection no longer performs the zoom - in operation, the function of the area of key interest can be exited in a timely manner, which is beneficial to reducing the situation where image processing is performed without the relevant person's key attention.

[0082] Figure 5 It is a schematic diagram of the partial image corresponding to the local area displayed in the browsing window deepened in the global window according to the embodiment of the image processing method of the present disclosure.

[0083] Reference Figure 5 , in some embodiments, performing image processing on the partial image corresponding to the local area displayed in the browsing window 2 in the global window 1 includes: adjusting at least one of brightness, hue, and transparency of the partial image corresponding to the local area displayed in the browsing window 2 in the global window 1.

[0084] Adjusting the brightness can be, for example, reducing the brightness. Adjusting the transparency can be, for example, reducing the transparency. Reducing the brightness and / or reducing the transparency will make the color of the processed partial image darker and thus more eye - catching. Adjusting the hue can be, for example, adjusting the hue from cold color to warm color to be more eye - catching.

[0085] Figure 6 It is a schematic diagram of some embodiments of superimposing and deepening the partial image corresponding to the local area displayed in the browsing window 2 translated to the right in the global window 1 according to the embodiment of the image processing method of the present disclosure.

[0086] Reference Figure 6, in some embodiments, the image processing method further includes: when the timing of the function of the area of key concern reaches multiple preset durations, performing an overlay adjustment of at least one of brightness, hue, and transparency on a partial image corresponding to the local area displayed in the browsing window 2 in the global window 1, so as to further highlight the partial image in the global window 1. In this way, gradient marking display will be performed in the global window 1 according to the different inspection time lengths of different parts of the image, so as to more clearly distinguish the degree of attention to different parts of the image.

[0087] Performing an overlay adjustment of at least one of brightness, hue, and transparency on a partial image corresponding to the local area displayed in the browsing window 2 in the global window 1 may include performing the same or different processing on the above partial image each time. The overlay adjustment means performing the next processing on the basis of retaining the result of the previous processing.

[0088] The same processing may be to adjust the same parameters of the above partial image by the same amplitude. For example, the processing may be to reduce the brightness (L) by 10 in the HSLA space. After one processing, the brightness of the partial image with a brightness of 100 is adjusted to 90. After another processing, the brightness of the partial image with a brightness of 90 is adjusted to 80. And so on, which will not be elaborated here. It should be understood that each processing may also adjust more than one of brightness, hue, and transparency at the same time.

[0089] For example, for the case where the preset duration is 5 seconds, the area with a timing reaching 10 seconds will have a lower brightness or a darker color than the area with a timing reaching 5 seconds but not reaching 10 seconds.

[0090] Different processing includes different adjustment amplitudes for the same parameters. For example, the first processing may be to reduce the brightness by 10 in the HSLA space, and the second processing may be to reduce the brightness by 9 in the HSLA space, with different values adjusted each time.

[0091] Different processing also includes adjusting different parameters each time. For example, the first processing may be to assign a cold color hue (such as 225), a preset brightness, and a preset transparency in the HSLA space. Starting from the second processing, the hue is reduced each time without changing other parameters. In this way, the processed global window 1 is similar to a heat map, and the color of the partial image with more overlay adjustment times will be warmer, indicating a longer inspection time and higher attention.

[0092] In this way, the relevant personnel inspecting the image of the object to be inspected can judge the inspection duration of each part of the image through the color information in the global window 1, so as to supplement the inspection of the area with a shorter inspection duration, or reconfirm the area with a longer inspection duration, etc. This can provide effective prompts and help for the inspection process of the relevant personnel and is conducive to improving the inspection results.

[0093] In some embodiments, the image processing method further includes saving the image of the global window 1 that has undergone image processing. This can archive the inspection history. By viewing the image processing results of the processed images, the inspection process of the image of the object to be inspected can be restored to a certain extent. Or statistical research can be conducted on the historical inspection data.

[0094] Figure 7 is a schematic diagram of some embodiments of the image inspection device according to the present disclosure. Refer to Figure 7 , the image inspection device 11 includes a memory 111 and a processor 112. The processor 112 is coupled to the memory 111 and is configured to execute the foregoing image processing method based on the instructions stored in the memory 111.

[0095] The memory 111 may include, for example, a system memory, a non-volatile storage medium, etc. The system memory stores, for example, an operating system, application programs, a boot loader, and other programs. The system memory may include a volatile storage medium, such as a random access memory (RAM) and / or a cache memory. The non-volatile storage medium stores, for example, instructions for implementing at least one of the corresponding embodiments of the vehicle detection method.

[0096] The processor 112 may be implemented in the form of a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gates, or discrete hardware components such as transistors. Correspondingly, each module such as a judgment module and a determination module may be implemented by a central processing unit (CPU) running instructions for executing corresponding steps in the memory, or may be implemented by a dedicated circuit for executing the corresponding steps.
