[0026] Embodiment 1

[0027] Figure 1 1 is a flow chart of a sample scanning method provided according to the first embodiment of the present invention. This embodiment is applicable to the case of scanning samples. The method can be performed by a sample scanning device. The sample scanning device can be implemented in the form of hardware and / or software. The sample scanning device can be configured in a computing device. Figure 1 As shown, the method includes:

[0028] S110, determining a sample to be tested, and dividing the sample to be tested to obtain at least two samples to be scanned in preset shapes.

[0029] The sample to be tested may be a rock sample, and its shape may be a cuboid (including a cube) or other shapes. The preset shape at least includes a cuboid. The number of samples to be scanned may be 2, 4 or other numbers, and the specific number may be determined according to the sample properties of the sample to be tested or the actual working conditions. The more the number of divided samples to be tested is, the higher the accuracy of scanning and measuring them is.

[0030] In this embodiment, in order to ensure that the sample to be tested can be placed stably on the cutting table, the side of the sample to be tested placed on the cutting table can be a flat surface. After the sample to be tested is placed on the cutting table, a cutting instruction can be sent to the cutting device, so that the cutting device cuts the sample to be tested into a plurality of samples to be scanned of the same size and preset shape.

[0031] In order to improve the accuracy of segmentation, the cutting surface of the sample to be tested can be identified by a recognition algorithm, and the sample can be segmented from the cutting surface to obtain at least two samples to be scanned. In this embodiment, in the process of segmenting the sample to be tested to obtain at least two samples to be scanned in preset shapes, at least one to-be-segmented line on the sample to be tested can be determined; the sample to be tested is segmented according to the to-be-segmented line to obtain at least two samples to be scanned in preset shapes.

[0032] It should be noted that when scanning a sample, the sample will be rotated so that the scanning device can fully scan the sample. In order to ensure that the scanning accuracy of the scanning device for the sample at each rotation angle is the same and is not reduced during the rotation of the sample to be scanned, the two opposite faces in the preset shape (such as front and back, up and down, or left and right) can be squares. Furthermore, the square face can be placed on a rotating table, and the distance between the sample and the scanning device can remain unchanged during scanning, and the scanning accuracy does not change.

[0033] In practical applications, the cutting surface of the sample to be tested can be determined. For example, assuming that the side of the sample to be tested placed on the cutting table is the bottom side, the top side of the sample to be tested can be used as the cutting surface. By identifying the cutting surface, marking the line to be cut on the cutting surface, and controlling the cutting device to cut along the line to be cut, at least two samples to be scanned of preset shapes are obtained. For example, the line to be cut can be the center line of the cutting surface, and the sample to be tested is equally divided along the center line into a number of (such as 4) samples to be scanned whose top and bottom sides are squares, that is, the XY axis direction is a square, and the front, back, left and right sides are rectangular.

[0034] S120 , for each sample to be scanned, the samples to be scanned on the mobile operating table at different rotation angles are scanned respectively based on the fixed scanning device to obtain a scanned image corresponding to the sample to be scanned.

[0035] Among them, the fixed scanning equipment can be a stone scanner, a core scanner, a CT scanning equipment, etc., which is fixed at a preset position. The mobile operating table has the function of rotating and moving. When the sample to be scanned is placed on the mobile operating table, the sample to be scanned can rotate with the rotation of the mobile operating table and move with the movement of the mobile operating table. The rotation angle can be preset, such as 90 degrees, 180 degrees, 240 degrees, etc. It should be noted that each sample to be scanned has the same shape and the same scanning method, and any of the samples to be scanned can be used as an example for introduction.

[0036] In this embodiment, the sample to be scanned can be placed on the mobile operating table. When the mobile operating table is at the rotation angle, the sample to be scanned on the mobile operating table is scanned based on the fixed scanning device. After the scanning is completed at the rotation angle, it can be rotated to the next rotation angle and continue scanning until the sample to be scanned at each rotation angle is scanned. The scanned image can be used as the scanned image corresponding to the sample to be scanned. The image can be an X-ray image, a tomographic image, a CT image, etc. The type of the image is related to the fixed scanning device.

[0037] It should be noted that when scanning a sample to be scanned based on a fixed scanning device, the radiation source emitted by the scanning device may not cover the sample surface of the sample to be scanned that faces the scanning device, resulting in incomplete scanning data. The mobile operating table can be moved to drive the sample to be scanned so that the sample surface of the sample to be scanned that faces the scanning device is completely scanned by the fixed scanning device.

[0038] In this embodiment, samples to be scanned on a mobile operating table at different rotation angles are scanned based on a fixed scanning device to obtain scanning images corresponding to the samples to be scanned, including: for each rotation angle, when the mobile operating table is at the rotation angle, determining a scanning area corresponding to the sample to be scanned on the mobile operating table; determining a moving path corresponding to the mobile operating table based on the position information and scanning area of ​​the fixed scanning device; and controlling the fixed scanning device to emit a radiation source in the process of the mobile operating table moving along the moving path to obtain a scanning image corresponding to the sample to be scanned.

[0039] The scanning area includes scanning dimensions, such as length and width. The scanning method at each rotation angle is the same, and any rotation angle may be used as an example for introduction.

[0040] In actual applications, when the mobile operating table is at a rotation angle, because the fixed scanning device is fixed, all fixed scanning devices will scan the sample surface of the sample to be scanned facing the fixed scanning device at the rotation angle. At this time, the range area of ​​the sample surface can be used as the scanning area. The moving path of the mobile operating table is planned through the position information and scanning area of ​​the fixed scanning device. In the process of the mobile operating table moving along the moving path, the fixed scanning device is controlled to emit a ray source, and the fixed scanning device can scan the entire scanning area, that is, scan a sample surface. Accordingly, a scanning image corresponding to the sample to be scanned can be obtained.

[0041] In this embodiment, the sample to be scanned is a rectangular sample. After the square surface of the sample to be scanned (called the bottom) is placed on the mobile operating table, the front, back, left and right surfaces of the sample to be scanned can be scanned respectively. At this time, multiple rotation angles can be set so that under the rotation angle, the front, back, left or right surface of the sample to be scanned can face the emission surface corresponding to the emission source of the fixed scanning device.

[0042] In this embodiment, determining the rotation angle includes: determining the rotation angle according to orientation information of multiple sample surfaces of the sample to be scanned on the mobile operating table and direction information of the emission surface of the fixed scanning device.

[0043] Wherein, the number of rotation angles is at least four.

[0044] Specifically, when the orientation information of a sample surface of the sample to be scanned on the mobile operating table is relative to the direction information of the emission surface of the fixed scanning device, a rotation angle is determined. When the orientation information of different sample surfaces is relative to the direction information of the emission surface, different rotation angles are determined. When the four sample surfaces of the front, back, left, and right of the sample to be scanned on the mobile operating table are respectively relative to the emission surface, there is a rotation angle respectively, and accordingly, at least four rotation angles are obtained, such as 0 degrees, 90 degrees, 180 degrees, and 270 degrees.

[0045] For example, place the sample on the operating table to ensure that any sample surface (there are 4 surfaces in total) in the YZ axis direction faces the radiation source. Start scanning the first sample surface, control the operating table to move from left to right, fix the scanning device to scan, rotate the operating table 90° after scanning, and then proceed to the next sample surface to complete the sample scanning. Scan each sample to be scanned in turn. Since the sample to be scanned is thinner than the sample to be tested and the center is closer to the radiation source, the resolution is improved, thereby improving the quality of the scanned image.

[0046] S130 , determining the porosity of the sample to be tested based on each scanned image.

[0047] In this embodiment, the porosity of the sample to be tested can be obtained by identifying the pore features in the scanned image. Specifically, based on each scanned image, the porosity of the sample to be tested can be determined by: fusing each scanned image according to the position information of the multiple samples to be scanned before cutting to obtain a fused image; and determining the porosity of the sample to be tested based on the fused image.

[0048] In practical applications, data processing software can be used to stitch together the scanned images based on the position information of multiple samples before segmentation to obtain pore data with higher resolution, i.e., fused images. The porosity of the sample to be tested can be determined by the pore features in the stitched fused images.

[0049] In this embodiment, determining the porosity of the sample to be tested according to the fused image includes: determining the pore volume of the sample to be tested according to the fused image; and determining the porosity based on the sample volume and the pore volume of the sample to be tested.

[0050] Specifically, the sum of the volumes of all pore spaces in the sample to be tested can be determined as the pore volume by identifying the pore features in the fused image. The quotient of the pore volume and the sample volume of the sample to be tested can be used as the total porosity of the sample to be tested, i.e., the porosity. The porosity can be expressed as a percentage, a decimal, a fraction, etc.

[0051] On the basis of the above scheme, the sample scanning method also includes: when it is detected that the sample to be tested meets the preset detection conditions, controlling the fixed scanning device to scan at least two sample surfaces of the sample to be tested respectively to obtain a sample image corresponding to the sample to be tested; determining the porosity of the sample to be tested based on the sample image.

[0052] The preset detection conditions may include detection conditions for the size, shape, material, etc. of the sample.

[0053] In this embodiment, when any one of the size, shape, and material of the sample to be tested meets the corresponding limiting condition in the preset detection condition, the sample to be tested is considered to meet the preset detection condition. Alternatively, when any two combinations of the size, shape, and material of the sample to be tested meet the corresponding limiting condition in the preset detection condition, the sample to be tested is considered to meet the preset detection condition. When the sample to be tested meets the preset detection condition, the fixed scanning device can be controlled to scan at least two sample surfaces of the sample to be tested respectively to obtain a sample image corresponding to the sample to be tested. Further, the porosity of the sample to be tested is determined by the sample image.

[0054] For example, if the sample to be tested is a square sample in the XY axis direction, the square surface of the sample can be placed on the operating table to ensure that any sample surface in the YZ axis direction (there are 4 surfaces in total) faces the radiation source. Start scanning the first sample surface, control the operating table to move from left to right, fix the scanning device to scan, and after scanning, rotate the operating table 90°, and then proceed to the next sample surface, thus completing the sample scanning.

[0055] The technical solution of this embodiment determines the sample to be tested and divides it to obtain at least two samples to be scanned with preset shapes, wherein the preset shape includes at least a cuboid; for each sample to be scanned, the sample to be scanned on the mobile operating table at different rotation angles is scanned based on a fixed scanning device to obtain the corresponding scanned image of the sample to be scanned; based on each scanned image, the porosity of the sample to be tested is determined, which solves the problem of low scanning accuracy and poor effect caused by the scanning method based on cylindrical samples in the prior art, and realizes that by dividing the sample to be tested into multiple samples to be scanned with preset shapes, deeper pores in the sample can be scanned, and at the same time, when scanning the samples to be scanned at different rotation angles, the scanning source is ensured to be consistent with the center of the sample to be scanned at each rotation angle, thereby improving the scanning accuracy. Furthermore, the porosity of the sample to be tested is determined by the scanned images of each sample to be scanned, and automatic scanning is realized to improve the sample scanning efficiency, reduce the scanning cost, and achieve the technical effect of improving the porosity acquisition accuracy.

[0056] Embodiment 2

[0057] As an optional embodiment of the above embodiment, in order to make those skilled in the art further understand the technical solution of the embodiment of the present invention, a specific application scenario example is given. For details, please refer to the following specific content.

[0058] It should be noted that, since reducing the distance between the sample center and the radiation source can directly improve the scanning resolution, when scanning a sample, it can be divided into equal parts vertically (Z axis). At this time, the thickness of the divided sample will be smaller than that of the sample before division, the distance between the sample center and the radiation source will be reduced, and the scanning resolution will be improved. Furthermore, the divided samples can be scanned separately, and then the scanned data volumes can be superimposed according to the coordinates of the division points.

[0059] Exemplarily, the sample to be measured (i.e., the sample to be measured) is cut into a square sample in the XY axis direction (i.e., the sample to be scanned). For example, the sample to be measured is equally divided into 4 square samples in the XY axis direction along the center line. The square surface of the sample to be scanned can be placed on the operating table to ensure that any sample surface in the YZ axis direction (a total of 4 surfaces) is facing the radiation source. Start scanning the first sample surface, control the operating table to move from left to right, fix the scanning device to scan, rotate the operating table 90°, and then proceed to the next sample surface, thus completing the sample scanning. Scan each sample to be scanned separately in turn. Since the sample to be scanned is thinner than the sample to be measured and the center is closer to the radiation source, the resolution is improved, thereby improving the quality of the scanned image. The scanned images can be spliced ​​using data processing software to obtain pore data with higher resolution. If the resolution needs to be further improved, the sample to be scanned is further cut and the scan is repeated.

[0060] The technical solution provided in this embodiment can realize precise positioning and precise cutting inside the sample by cutting the sample into a square sample with XY axis, and can be divided into 4 small squares along the center line (rectangle in the Z axis direction). When scanning each sample surface, the operating table is controlled to scan from left to right. After scanning, the operating table is rotated 90°, and the next sample surface is scanned to realize sample scanning. It is achieved that the distance between the sample and the radiation source remains unchanged during scanning without reducing the resolution. At the same time, the data body (i.e., the scanned image) obtained after scanning each square sample is losslessly spliced ​​to obtain pore data with higher resolution, thereby improving the quality of the sample data and the accuracy of the sample porosity determination.
