The force acting on the object to be measured can be adjusted according to the material and cutting requirements of the object to be measured. The proximity sensor 26 is arranged beside the displacement sensor 211 for detecting the cutting thickness, namely the proximity sensor 26 corresponding to the slicing device 21 and arranged on the horizontal conveying device, the proximity sensor 26 plays a role in safety protection, and the situation that the displacement sensor 211 for detecting the cutting thickness is damaged due to the fact that the slicing thickness is too large is prevented.
Specifically, as shown in fig. 6, the image processing unit 3 in the system includes: the system comprises an image acquisition module 31, an image segmentation and extraction module 32, a space three-dimensional coordinate acquisition module 33 and a three-dimensional body reconstruction module 34; wherein,
the image acquisition module 31 is connected to the image segmentation and extraction module 32, and is configured to acquire a two-dimensional tomographic color image of the surface of the object to be measured after being sliced, cleaned, and dried by the mechanical operation unit 2, and send acquired image data to the image segmentation and extraction module 32;
the image segmentation and extraction module 32 is connected with the image acquisition module 31 and the spatial three-dimensional coordinate acquisition module 33, specifically, the controller 1 controls the image acquisition module 31 to acquire images of the dried object to be measured, and inputs each two-dimensional tomographic color image acquired by the images to the image segmentation and extraction module 32, the image segmentation and extraction module 32 segments and extracts various colors, feature points and boundaries in each two-dimensional tomographic color image through a related digital image algorithm, and sends each two-dimensional tomographic feature image after the segmentation and extraction to the spatial three-dimensional coordinate acquisition module 33; the digital image algorithm technology may be any commonly used technology, and is not specifically limited by those skilled in the art.
The spatial three-dimensional coordinate acquisition module 33 is connected with the image segmentation and extraction module 32 and the three-dimensional body reconstruction module 34; the image segmentation and extraction module 32 just segments and extracts the relevant feature points in each two-dimensional tomographic color image, and then generates three-dimensional coordinates corresponding to the segmented and extracted two-dimensional tomographic color image, and sends the generated three-dimensional coordinates to the three-dimensional reconstruction module 34. Therefore, in the first embodiment, specifically: the spatial three-dimensional coordinate acquisition module 33 generates a three-dimensional coordinate for each point in each two-dimensional tomographic feature image, and the spatial three-dimensional coordinate acquisition module 33 may generate a spatial three-dimensional coordinate of the object to be measured according to the three-dimensional coordinate of each point. The above forms a point cloud picture of the three-dimensional space coordinate of the measured object. Specifically, each point generates a three-dimensional coordinate, and x and y coordinate units on each point are pixels, and z coordinate units are layers, so that all the x and y coordinate units must be converted into an international unit system to generate a spatial three-dimensional coordinate of a measured object later. Therefore, the real value of the z coordinate can be obtained by the product of the layer number and the actual distance of each layer during cutting, and the real value of the x and y coordinates needs to be obtained by a target surface resolution calibration test of the image acquisition equipment.
The three-dimensional body reconstruction module 34 is connected with the spatial three-dimensional coordinate acquisition module 33; the three-dimensional body reconstruction module 34 connects three points adjacent to each point in the cloud point image of the three-dimensional space coordinate formed by the three-dimensional space coordinate acquisition module 33 to form a triangular surface (or called a small plane), combines the triangular surfaces to form a closed area surface model, converts the area surface model into a three-dimensional internal structure body model containing the measured object, and generates a data format compatible with the current mainstream three-dimensional program.
The installation steps included in the above embodiments are only used as references, and for those skilled in the art, the sequential logic relationship of the implementation may be changed according to the actual needs, and are not listed here.
Hereinafter, the system for reconstructing a miniature sliced three-dimensional structure according to the present invention will be described in detail with reference to the following embodiments.
As shown in fig. 7, when the influence of the microscopic structure of the granite material on the mechanical properties of the granite material is studied, it is often necessary to know the three-dimensional structure diagram of the internal minerals and the microscopic defects. For obtaining its inside three-dimensional structure picture, can process into the granite material of research diameter at 2 ~ 6 cm's cylinder test piece, then pack this granite cylinder test piece into small-size slicing type three-dimensional structure reconstruction system in elevating platform 232's anchor clamps 235. If the thickness of the slice is 1mm, the slice is 100 slices, the thickness d of the needed slice is set to be 1mm through the controller 1, the total number of the slices is set to be 100, and the acquisition mode of the image acquired by the image processing unit 3 is set to trigger acquisition through the controller 1; with reference to fig. 1, the specific implementation steps are as follows:
firstly, a tested granite cylindrical test piece is installed in a clamp 235 on a lifting device 23 in a mechanical operation unit 2, a lifting table 232 in the lifting device 23 drives the granite cylindrical test piece to move downwards, a displacement sensor 211 for detecting the cutting thickness corresponding to a slicing device 21 detects whether the thickness of the slice required by the granite cylindrical test piece reaches 1mm in real time, and if the thickness reaches 1mm, the slicing device 21 is indicated to cut;
secondly, the controller 1 monitors the reading of the displacement sensor 211 for cutting the thickness in real time, if the reading is zero, the wheel is considered to be finished cutting, the cutting device is closed, and the lifting device 23 is lifted for a certain distance;
and thirdly, the cut granite is clamped by the clamp 235 in the lifting device 23 and is conveyed to the water tank (here, the cleaning device 24 is set as the water tank) through the horizontal conveying device 22. When the proximity sensor 26 at the position corresponding to the water tank monitors that the lifting device 23 arrives, a switch signal is sent out, the controller 1 opens the water tank after receiving the signal, and the lifting device 23 puts the cut granite into the water tank for cleaning;
after the cleaning is finished, according to the instruction of the controller 1, the lifting device 23 carries the cleaned granite to move to the drying device 25, and the drying device 25 dries the cut granite;
fifthly, after the drying is finished, the lifting device 23 carries the dried granite to move to the image processing unit 3, the image processing unit 3 carries out image acquisition on the cut granite surface, and the acquired color image data is processed and stored.
And sixthly, the lifting device 23 returns to the slicing device 21 through the horizontal conveying device 22 and starts the next round of cutting. This is repeated until the total number of slices is 100. And finishing slicing. After the slicing is finished, the image processing unit 3 performs three-dimensional reconstruction on the previously acquired 100 two-dimensional tomographic images, and can obtain a three-dimensional internal structure model of the granite to be studied. After the three-dimensional internal structure model is obtained, researchers can perform subsequent mechanical analysis.
