[0002] Currently, the inspection for metallic foreign objects in the body during cremation generally relies on manual methods. These methods primarily include: questioning family members: While inquiring about implants can reveal their presence, family members may be unaware, have forgotten, or be too grief-stricken to provide accurate information; and obtaining medical documentation: Some deceased individuals receive hospital-issued medical certificates, but these documents often lack details about implants once the body arrives at the funeral home. The lack of standardized and reliable testing procedures at most crematoriums poses certain safety risks during the cremation process. Summary of the Invention

Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0016] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0017] The following description, in conjunction with the accompanying drawings, details a cremation safety early warning method and system based on X-ray scanning provided in this application, through specific embodiments and application scenarios.

[0018] Please see Figure 1 This is a flowchart illustrating a cremation safety early warning method based on X-ray scanning, provided in an embodiment of this application. This method is applied to electronic devices. Figure 1 As shown, the method includes the following steps S100 to S400.

[0019] Step S100: Obtain a two-dimensional projection digital image of the remains inside the target coffin, the two-dimensional projection digital image being obtained by X-ray scanning.

[0020] In this embodiment, the target coffin can be understood as a coffin containing a body. When the target coffin (or paper coffin) containing the body is placed on the hearse in the crematorium's front hall, the body and coffin begin to enter the crematorium as the hearse moves. The hearse can be a tracked hearse or a trolley-type hearse. At this time, the scanning station is triggered, activating the vertical X-ray scanning device to perform one or more (e.g., frontal and lateral views) digital X-ray scans on the body inside the target coffin, acquiring two-dimensional projection digital images of the body inside the target coffin. The vertical X-ray scanning device is a medical X-ray device, referring to a digital X-ray imaging system that meets medical safety standards, such as DR, used to generate digital images of the internal structure of the human body or object.

[0021] Step S200: Preprocess the two-dimensional projected digital image to obtain a preprocessed image.

[0022] In this embodiment, after obtaining the two-dimensional projected digital image, the image is preprocessed to obtain a preprocessed image. Preprocessing may include, but is not limited to, noise reduction, contrast enhancement, and grayscale processing. Preprocessing improves image quality, thereby increasing the accuracy of subsequent recognition.

[0023] Step S300: Use a grayscale threshold segmentation image recognition algorithm to identify metal foreign objects in the preprocessed image to obtain the initial metal foreign objects.

[0024] In this embodiment, the grayscale threshold segmentation image recognition algorithm is a simple, efficient, and widely used image segmentation technique. Its core idea is to set one or more grayscale thresholds to classify pixels in an image into different categories (such as foreground and background) based on the comparison between their grayscale values ​​and the thresholds, thereby achieving separation of the target from the background. Since metallic foreign objects have a much stronger attenuation capability for X-rays than human tissue and coffin materials, they appear as extremely bright (nearly pure white) pixel areas in the image. After preprocessing the two-dimensional projection digital image, a grayscale image corresponding to the two-dimensional projection digital image can be obtained. The grayscale value of each pixel in the grayscale image is obtained, and pixels with grayscale values ​​greater than a preset grayscale threshold are identified as initial metallic foreign objects. Metallic foreign objects can refer to metallic objects that may exist in the remains or burial goods and pose a risk of explosion or ejection under high-temperature cremation conditions, such as pacemakers, deep brain stimulators, orthopedic implants, shrapnel, etc.

[0025] Step S400: In response to the initial metallic foreign object meeting the preset alarm conditions, an alarm message is sent.

[0026] In this embodiment, after identifying the initial metallic foreign object using a grayscale threshold segmentation image recognition algorithm, the initial metallic foreign object is further judged. A preset image library is obtained. The preset image library stores grayscale images corresponding to each metallic foreign object. The initial metallic foreign object is matched with images in the preset image library. When an image matching the initial metallic foreign object exists in the preset image library, the initial metallic foreign object is determined to meet preset alarm conditions. Once a metallic foreign object meeting the preset alarm conditions is identified, the system immediately triggers a linkage alarm and sends alarm information. The alarm may include, but is not limited to, visual alarms and audible and visual alarms.

[0027] Through steps S100-S400, a two-dimensional projection digital image of the remains inside the target coffin is acquired via X-ray scanning. The two-dimensional projection digital image is preprocessed to obtain a preprocessed image. A grayscale threshold segmentation image recognition algorithm is used to identify metallic foreign objects in the preprocessed image, yielding initial metallic foreign objects. In response to the initial metallic foreign object meeting preset alarm conditions, an alarm message is sent. Thus, this application utilizes the physical properties of X-rays to penetrate the coffin non-destructively and directly detect metallic foreign objects inside the human body, overcoming the shortcomings of manual methods that are prone to missed detections. It boasts high detection accuracy and, through non-contact and non-destructive methods, maximizes the preservation of the deceased's dignity. Furthermore, this application proactively and reliably identifies explosion risk sources through technical means, fundamentally avoiding the risk of injury to cremation personnel and equipment damage caused by the explosion of metallic foreign objects during the cremation process, providing crucial safety assurance for cremation personnel.

[0028] Pre-cremation metal foreign object detection can reliably identify sources of explosion risk, avoiding operator injury and equipment damage accidents caused by metal foreign object explosions, and improving the safety of cremation.

[0029] In some implementations, the alarm includes visual alarms and audible and visual alarms, and sending alarm information includes: An alarm message is sent to the display device to display the location of the target metal foreign object, wherein the target metal foreign object is the initial metal foreign object that meets the preset alarm conditions; An alarm message is sent to the audible and visual alarm device to trigger an audible and visual alarm.

[0030] Specifically, when a metallic foreign object that meets the preset alarm conditions is detected, the system immediately triggers a linkage alarm: sending alarm information to the display device and the audible and visual alarm.

[0031] A visual alarm is sent to the operator interface of the cremator's front hall control panel, highlighting the location of the metallic foreign object on the scanned image. Simultaneously, an alarm is sent to the audible and visual alarm system, emitting sound and light to alert on-site personnel to the risk. In one example, the audible and visual alarm system may include a buzzer and a warning light. Through this coordinated alarm system, the operator can take appropriate action according to safety procedures, such as: immediately stopping the hearse before cremation begins, having a professional operator temporarily remove any metallic foreign objects detected in the body, or adjusting the operator's position away from potentially hazardous areas such as the observation window in the cremator's rear hall.

[0032] Please see Figure 2 This is a flowchart illustrating a cremation safety early warning method based on X-ray scanning, provided in a specific embodiment of this application. Figure 2 As shown, this specific embodiment includes: Specifically, when the sealed coffin (or paper coffin) containing the remains is placed on the hearse (tracked hearse or trolley hearse) in front of the crematorium, the remains and coffin begin to enter the furnace as the hearse moves. At this time, the scanning station is triggered, and the vertical X-ray scanning device is started to perform one or more (such as front and side views) digital X-ray scans on the coffin to obtain two-dimensional projection digital images of the remains inside the coffin.

[0033] The image processing layer receives a two-dimensional projected digital image and performs the following core operations: (1) Preprocessing: The image is processed by noise reduction, contrast enhancement and other processes to improve the image quality.

[0034] (2) Metal foreign object identification: An image recognition algorithm based on grayscale threshold segmentation is adopted. Since metal foreign objects have a much stronger ability to attenuate X-rays than human tissue and coffin materials, they appear as pixel areas with extremely high brightness (close to pure white) in the image. The system sets a brightness threshold and automatically identifies and marks all connected regions that are higher than the threshold.

[0035] (3) Target screening (optional): Based on the common shape, size and common location of the metal foreign object in the human body (such as the chest cavity and pelvis), the identified area can be initially screened to reduce false alarms.

[0036] Once a metallic foreign object meeting the preset conditions is detected, the system immediately triggers a linked alarm: a visual alarm is sent to the operator interface of the crematorium control panel, and the location of the metallic foreign object is highlighted on the scanned image. Simultaneously, an audible and visual alarm is activated, providing both auditory and visual warnings to alert on-site personnel to the risk.

[0037] Based on the alarm information, the operator takes action in accordance with safety procedures. For example, the body transport vehicle may be stopped immediately before cremation begins, and professional operators may temporarily handle any metal foreign objects detected in the body, or the operator may adjust their position away from potentially dangerous areas such as the observation window in the back hall of the crematorium.
