DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example 1

[0042] See also Figure 1 , a method for accurately cutting an irregular object using X-rays is shown in the figure, the method comprising the following steps:

[0043] S1: X-ray scanning is used to obtain the internal structure of the rubber block. Industrial-grade X-ray scanning equipment is used to perform multi-angle scanning on the irregularly shaped rubber block to obtain two-dimensional image data of the internal structure of the rubber block to ensure that the density and internal morphology of the material can be reflected.

[0044] S2: Image processing: performing preprocessing such as noise removal and contrast enhancement on the acquired X-ray images, and using edge detection and contour extraction techniques to identify and segment the contour of the rubber block;

[0045] S3: 3D reconstruction, using voxel modeling and surface reconstruction algorithms to reconstruct 2D image data into a 3D model, accurately reflecting the internal structure and volume of the rubber block through the relationship between grayscale value and thickness;

[0046] S4: Calculate the cutting position.

[0047] Preferably, in step S2, edge detection and contour extraction are used to identify and segment the contour of the rubber block, and Gaussian filtering, histogram equalization and other operations are performed on the X-ray image to eliminate noise and improve contrast. Canny edge detection or Sobel operator and other methods are used to identify edges and contours in the image;

[0048] The implementation process includes:

[0049] S201: Image preprocessing. When processing an X-ray image of an irregular rubber block, the original image must first be preprocessed to remove noise and highlight areas of interest (such as defects or irregular shapes).

[0050] Input image: X-ray scan image I, size m×n, representing the two-dimensional projection of the irregular rubber block;

[0051] Denoising: Use a 3×3 Gaussian filter to denoise the image. The filtered image is: The filter size is small here to avoid over-smoothing and losing the details of the rubber block.

[0052] S202: Pyramid decomposition: In order to better analyze the multi-scale characteristics of the rubber block, an image pyramid decomposition method is used;

[0053] Gaussian filter: for I smooth Then a 5×5 Gaussian filter is performed to obtain a smooth image, making the large-scale areas more obvious.

[0054] Downsampling: Downsample the smoothed image to retain important structures, and the image size becomes m / 2×n / 2, obtaining the downsampled image R1. A simple alternate row and column sampling method can be used.

[0055] Detail extraction: The original image I smoothSubtract the interpolated and enlarged image to obtain the detail image D1 (size is m×n). This step is used to capture the edge or irregular area of ​​the rubber block.

[0056] Repeated downsampling: Update the image size and continue downsampling and detail extraction on R1 until the image size cannot be reduced further;

[0057] S203: Image enhancement, detail image D decomposed from each layer i Perform nonlinear enhancement processing;

[0058] Enhanced Formula: Using Formula where a i is the gain parameter of different layers, and p is the enhancement index. Let a1 = 1.5 for the first few layers and a2 = 1.2 for the last few layers to weight different details.

[0059] Local enhancement: Use a larger α value for the first three layers (the parts with less details but minor defects) to enhance their details. For the later layers, where details are already more significant, you can reduce the gain to reduce artifacts.

[0060] S204: Image reconstruction, after decomposing the multi-layer image, start to reconstruct the final enhanced image from the smallest image;

[0061] Upsampling: For the image R at the bottom layer (e.g., size m / 4×n / 4), k Upsample and restore to the size of the previous layer 2m×2n to obtain the interpolated image E k .

[0062] Detail superposition: interpolate and enlarge the image E k The enhanced detail image D corresponding to this layer enhanced Add and get the enhanced image R k-1 .

[0063] Layer-by-layer reconstruction: Repeat upsampling and detail superposition operations until the original image size m×n is restored. The final reconstructed image I final will include enhanced details and sharper edges;

[0064] S205: Contrast adjustment: In order to better display the defects inside the rubber block, the adaptive histogram equalization (CLAHE) technology is applied to enhance the local contrast.

[0065] Binarization and Defect Detection: Based on the pixel value distribution of the image, an appropriate threshold is set to binarize the image, highlighting defective areas in the rubber block. Connected domain analysis is performed on the binarized image to further identify possible defects such as cracks, irregular shapes, or bubbles.

[0066] Through this image processing process, important details in the X-ray image of irregular rubber blocks, such as edges and defects, can be effectively enhanced, facilitating subsequent automatic detection and analysis.

[0067] Preferably, in step S3, voxel modeling or surface reconstruction algorithm is used to reconstruct the two-dimensional image data into a three-dimensional model. The internal structure and volume of the rubber block can be accurately reflected through the relationship between grayscale value and thickness;

[0068] Implementation: The segmented 2D image is fed into a 3D reconstruction algorithm to generate a 3D model of the rubber block. Based on the mapping relationship between grayscale value and thickness, the thickness of each voxel is calculated to construct an accurate 3D volume model.

[0069] Preferably, step S4 includes grayscale value and thickness mapping and volume ratio calculation,

[0070] 1. Grayscale value and thickness mapping: Establish a mapping relationship between grayscale value and thickness, and determine the proportional constant through experimental calibration. Calculate the total volume of the rubber block based on the reconstructed 3D model;

[0071] 2. Calculate the volume ratio:

[0072] The density formula shows that, given the same density, weight and volume are directly proportional. Therefore, knowing the total weight and volume of the entire irregular rubber block allows us to calculate the proportion of the volume of the rubber block that needs to be cut relative to the total volume.

[0073] Implementation process:

[0074] The proportional constant k between grayscale value and thickness is determined through experimental calibration.

[0075] For each pixel in the 3D model, calculate its thickness T = k*gray (i，j) , where gray (i,j) is the grayscale value.

[0076] Therefore, the formula for calculating volume can be expressed as:

[0077]

[0078] It can be known that the ratio of the volume of the rubber block that needs to be cut to the total volume of the rubber block.

[0081] The scanning body 101 has a mounting frame 102 fixed to its upper end. A lens 103 for auxiliary scanning is mounted on the mounting frame 102 in a movably movable manner. A placement table 104 for placing a rubber block is provided above the scanning body 101. The scanning body 101 is provided with a rotating assembly for rotating the placement table 104. The placement table 104 is provided with a pressure assembly for preventing the rubber block from shifting after placement.

[0082] Multiple groups of pressure components are evenly distributed in a circular array on the placement table 104. The pressure components include a mounting plate 301. The placement table 104 is provided with a sliding component for slidingly connecting the mounting plate 301. An air pump 302 is installed on the mounting plate 301.

A transmission component for transmitting each group of mounting plates 301 is provided below the placement table 104.

[0083] It should be noted here that: the distance between each group of mounting plates 301 and the placed rubber block is adjusted by the movement of each group of mounting plates 301. After the distance adjustment is completed, the blowing action of the blowing pump 302 causes external air to blow toward the placed rubber block through the air pipe 303. The blowing action generates pressure around the placed rubber block, thereby preventing the rubber block from shifting during the scanning and measurement process, which may cause scanning deviation.

[0084] Preferably, the sliding assembly includes a mounting groove 401 provided on the placement platform 104, a slide plate 403 being slidably connected to the mounting groove 401, the mounting plate 301 being fixed to the slide plate 403, T-slots 402 being provided on opposite sides of the mounting groove 401, two sets of T-slots 402 being slidably connected to T-blocks 404, and two sets of T-blocks 404 being fixed to the two sides of the slide plate 403 respectively;

[0085] It should be noted that the mounting groove 401 , the T-slot 402 and the T-block 404 facilitate the sliding guidance of the slide plate 403 after receiving force.

[0087] It should be noted here that: the driving disk 501 is subjected to force and moves through the driving assembly. During the process of the driving disk 501 being subjected to force, the annular plate 601, the annular groove 602 and the connecting ring 603 provide rotational guidance for the driving disk 501 after being subjected to force, so that the driving disk 501 after being subjected to force rotates under the placement table 104.

[0088] Preferably, the guide assembly includes an annular plate 601 sleeved on the outside of the placement table 104, the annular plate 601 is fixed on the driving disk 501, and the annular plate 601 and the driving disk 501 are concentrically arranged. An annular groove 602 is opened on the outside of the placement table 104, and a connecting ring 603 is rotatably connected to the inside of the annular groove 602. The connecting ring 603 is fixed to the inner side of the annular plate 601;

[0089] It should be noted that the annular plate 601 , the annular groove 602 and the connecting ring 603 provide a rotational guide for the driven disk 501 after the force is applied, so that the driven disk 501 rotates below the placement platform 104 after the force is applied.

[0090] Preferably, the driving assembly includes a ring gear 701 sleeved and fixed on the outer side of the driving disk 501, an L-shaped frame 702 is fixed to the upper end of the placement table 104, a mounting shaft 703 is rotatably connected to the L-shaped frame 702, a gear 704 is fixed to one end of the mounting shaft 703, the gear 704 and the ring gear 701 are meshed with each other, and a first motor 705 for driving the mounting shaft 703 is installed on the L-shaped frame 702;

[0091] It should be noted here that: the first motor 705 is driven to drive the mounting shaft 703 and the gear 704 on the mounting shaft 703 to rotate. During the rotation of the gear 704, the drive disk 501 is forced to move through the mutual engagement transmission between the gear 704 and the ring gear 701.

[0092] Preferably, the rotating assembly includes a support frame 201 fixed to the inner side of the scanning body 101, a rotating shaft 202 is rotatably connected to the support frame 201, one end of the rotating shaft 202 is used to be fixed to the lower end of the placement table 104, the driving disk 501 is sleeved on the outer side of the rotating shaft 202 through the mounting hole, and a second motor 203 for driving the rotating shaft 202 is installed on the support frame 201;

[0093] It should be noted that the second motor 203 drives the rotating shaft 202 to rotate, and during the rotation of the rotating shaft 202 , the placement platform 104 is driven to rotate.

[0094] The process of scanning a rubber block using industrial-grade X-ray scanning equipment includes the following steps:

[0095] The rubber block to be cut is placed centrally on the placement table 104. During the placement process, the rubber block is positioned between the groups of pressure components. After the placement is completed, the first motor 705 is driven to drive the mounting shaft 703 and the gear 704 on the mounting shaft 703 to rotate. During the rotation of the gear 704, the gear 704 and the ring gear 701 are meshed with each other, causing the driving disc 501 to move under the force. During the process of the driving disc 501 being subjected to force, the annular plate 601, the annular groove 602 and the connecting ring 603 guide the rotation of the driven disc 501 after the force is applied, so that the driven disc 501 rotates below the placement table 104.

[0096] During the rotation of the driving disk 501, the interaction between each group of inclined slots 502 and each group of transmission pins 503 causes each group of slide plates 403 to be subjected to force and slide on each group of mounting slots 401. During the movement of the slide plates 403, the sliding guide effect of the T-slots 402 and the T-blocks 404 on the slide plates 403 after the force is applied causes each group of slide plates 403 to move towards or away from each other on the placement table 104 after the force is applied. During the movement of each group of slide plates 403, each group of mounting plates 301 is driven to move towards or away from each other synchronously. Through the movement of each group of mounting plates 301, the distance between each group of mounting plates 301 and the placed rubber block is adjusted. After the distance adjustment is completed, the blowing effect of the blowing pump 302 causes external gas to be blown toward the placed rubber block through the air pipe 303. The blowing effect generates pressure around the placed rubber block to prevent the rubber block from shifting during the scanning and measurement process, which causes scanning deviation.

[0097] After the rubber block is positioned and placed and the blowing pressure is provided, the rubber block is scanned through the lens 103. During the scanning process, the placement table 104 is driven to rotate through the rotating component. During the rotation of the placement table 104, the placed rubber block is driven to rotate. The rotation of the rubber block facilitates more efficient scanning processing.
