[0002] Fiber optic image transmission components (such as fiber optic panels, image invertors, light cones, etc.) are fiber optic material rod bundles composed of tens to hundreds of thousands of micron-level optical fibers. Among them, the optical fiber that constitutes the fiber optic image transmission component is drawn by sheathing a hollow glass tube on a core glass rod, that is, the processing quality of the optical fiber depends on the processing quality of the glass tube.

Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein.

[0033] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0034] At present, laser detection is usually used to detect the processing parameters of glass tubes, and then the processing quality of glass tubes is judged based on the processing parameters of glass tubes. In the process of detecting the processing parameters of glass tubes by laser detection, two lasers are needed to perform multiple point scanning operations on the glass tubes. However, only when the staff rotates the glass tubes or rotates the lasers manually multiple times can the operation of multiple point scanning on the glass tubes be completed. Therefore, the detection of the processing parameters of glass tubes by laser detection requires a lot of time and labor costs, and the detection efficiency is low.

[0035] Therefore, in order to improve the detection efficiency of glass tube processing parameters, the present application embodiment provides a glass tube processing parameter detection system, such as Figure 1 As shown, the system includes: a tube lowering platform 1, a conveying device 2, a plurality of clamping devices 3, a tube lowering basket 4, a terminal device 5 and a photographing device 6;

[0036] The output end of the lower tube platform 1 is connected to the input end of the conveying device 2, and the lower tube basket 4 is arranged below the output end of the conveying device 2. The input end of the lower tube platform 1 is used to put the glass tube to be tested;

[0037] The conveying device 2 is electrically connected to the terminal device 5, and the conveying device 2 includes a conveying belt 21 and a conveying belt rotating shaft 22. A plurality of fixture devices 3 are arranged on the conveying belt 21, and the fixture devices 3 are used to fix the glass tube to be tested;

[0038] The photographing device 6 is disposed on one side of the conveying device 2, and the photographing device 6 is electrically connected to the terminal device 5. The photographing device 6 is used to photograph the end surface image corresponding to the glass tube to be inspected, and send the end surface image corresponding to the glass tube to be inspected to the terminal device 5;

[0039] The terminal device 5 is used to control the conveyor belt shaft 22 to start and stop rotating, and to determine the processing parameters corresponding to the glass tube to be inspected according to the end surface image corresponding to the glass tube to be inspected.

[0040] Wherein, the glass tube to be detected is a glass tube used to manufacture optical fibers, the circle surrounded by the outer edges of the end faces of the glass tube to be detected is the outer circle corresponding to the glass tube to be detected, the circle surrounded by the inner edges of the end faces of the glass tube to be detected is the inner circle corresponding to the glass tube to be detected, the inner circle drawing diameter and the outer circle drawing diameter corresponding to the glass tube to be detected can be but are not limited to: 25mm / 27mm, 29mm / 36mm, 34mm / 35mm, 40mm / 42mm, etc., and the embodiments of the present application do not specifically limit this; wherein, the lower tube platform 1 can specifically be a glass platform made of glass material, the lower tube platform 1 is placed at an angle, the width of the lower tube platform 1 is the same as the width of the conveyor belt 21, and the width of the lower tube platform 1 is the same as the width of the conveyor belt 21. The width of the belt 21 is greater than the length of the glass tube to be detected; wherein, the spacing between the output end of the lower tube platform 1 and the input end of the conveying device 2 is determined according to the outer circle drawing diameter corresponding to the glass tube to be detected and the height of the clamping device 3. For example, the height of the clamping device 3 is 6 mm, and the outer circle drawing diameter corresponding to the glass tube to be detected is 36 mm. Then, the spacing between the output end of the lower tube platform 1 and the input end of the conveying device 2 can be set to 12 mm, thereby ensuring that the glass tube to be detected will not fall to the ground from the gap between the output end of the lower tube platform 1 and the input end of the conveying device 2, and ensuring that the clamping device 3 can pass through the gap between the output end of the lower tube platform 1 and the input end of the conveying device 2.

[0041] Among them, the distance between two adjacent clamping devices 3 can be determined according to the outer circle drawing diameter corresponding to the glass tube to be detected, that is, to ensure that the distance between two adjacent clamping devices 3 is not much different from the outer circle drawing diameter corresponding to the glass tube to be detected. For example, if the outer circle drawing diameter corresponding to the glass tube to be detected is 36 mm, the distance between two adjacent clamping devices 3 can be set to 35 mm.

[0042] Among them, the conveyor belt shaft 22 is used to drive the conveyor belt 21 to rotate, the input end of the lower tube platform 1 is used to put the glass tube to be inspected, and the glass tube to be inspected rolls from the input end of the lower tube platform to the clamping device 3. The conveyor belt 21 drives the clamping device 3 and the glass tube to be inspected to move from the input end of the conveying device 2 to the output end of the conveying device 2. The lower tube basket 4 is used to receive the glass tube to be inspected that falls from the output end of the conveying device 2.

[0043] The lower tube basket 4 is filled with cotton or other buffer materials to prevent the glass tube to be tested from colliding and breaking when it falls into the lower tube basket 4 .

[0044] The following specifically describes the glass tube processing parameter detection system in the embodiment of the present application through the working process and principle of the glass tube processing parameter detection system in the embodiment of the present application:

[0045] The positions of the various clamping devices 3 on the conveyor belt 21 are adjusted in advance by controlling the rotation of the conveyor belt shaft 22, thereby ensuring that there is a clamping device 3 at the input end of the conveyor device 2 (ie, the input end of the conveyor belt 21).

[0046] First, the glass tubes to be detected are placed at the input end of the lower tube platform 1 according to the preset placement interval, that is, after the first glass tube to be detected is placed and the preset placement interval has passed, the second glass tube to be detected is placed, after the second glass tube to be detected is placed and the preset placement interval has passed, the third glass tube to be detected is placed...; and, after the first glass tube to be detected is placed and the target rolling time has passed, the terminal device 5 controls the conveyor belt rotating shaft 22 to start rotating to drive the conveyor belt 21 to transmit, wherein the target rolling time is the time for the glass tube to be detected to be transported from the lower tube platform 1 to the input end of the lower tube platform 1. The time required for the input end to roll down to the output end of the lower tube platform 1 is calculated, so that after the first glass tube to be detected is placed and the target rolling time has passed, the glass tube to be detected can just roll down to the clamping device 3 at the input end of the conveying device 2; wherein, since the transmission speed of the conveyor belt 21 is determined according to the preset placement interval time, the target rolling time, the spacing between adjacent clamping devices 3 and the size of the clamping device 3, it can be ensured that after the conveyor belt 21 is driven, each glass tube to be detected placed at the input end of the lower tube platform 1 can roll down to the corresponding clamping device 3.

[0047] Secondly, after the conveyor belt 21 is driven, the conveyor belt 21 can drive the clamping device 3 and the glass tube to be detected to move from the input end of the conveying device 2 to the output end of the conveying device 2. When the clamping device 3 and the glass tube to be detected move to the output end of the conveying device 2, the glass tube to be detected will fall into the lower tube basket 4. At this time, the staff needs to pick up the glass tube to be detected in the lower tube basket 4 in time to avoid the glass tube to be detected that subsequently falls into the lower tube basket 4 and collides with and breaks the glass tube to be detected; wherein, during the movement of the clamping device 3 and the glass tube to be detected, when the clamping device 3 and the glass tube to be detected move into the shooting range of the shooting device 6, the shooting device 6 can shoot the end face of the glass tube to be detected to obtain the end face image corresponding to the glass tube to be detected, and send the end face image corresponding to the glass tube to be detected to the terminal device 5.

[0048] Finally, the terminal device 5 determines the processing parameters corresponding to the glass tube to be detected according to the end surface image corresponding to the glass tube to be detected, for example, the inner circle processing diameter, outer circle processing diameter and concentricity deviation value corresponding to the glass tube to be detected.

[0049] The glass tube processing parameter detection system can detect and obtain the processing parameters of a large number of glass tubes to be detected according to the above-mentioned work flow without the intervention of detection staff. Therefore, it can effectively reduce the time cost and labor cost consumed in detecting the processing parameters of the glass tubes to be detected, thereby effectively improving the detection efficiency.

[0050] The embodiment of the present application provides a glass tube processing parameter detection system, and the glass tube processing parameter detection system provided by the embodiment of the present application includes: a lower tube platform, a conveying device, a plurality of fixture devices, a lower tube basket, a terminal device and a shooting device; the output end of the lower tube platform is connected to the input end of the conveying device, the lower tube basket is arranged below the output end of the conveying device, and the input end of the lower tube platform is used to put the glass tube to be detected; the conveying device is electrically connected to the terminal device, the conveying device includes a conveyor belt and a conveyor belt rotating shaft, a plurality of fixture devices are arranged on the conveyor belt, the fixture device is used to fix the glass tube to be detected, the conveyor belt rotating shaft is used to drive the conveyor belt to rotate, and the glass tube to be detected is put at the input end of the lower tube platform. After the glass tube is detected, the glass tube to be detected rolls down from the input end of the lower tube platform to the fixture device, and the conveyor belt drives the fixture device and the glass tube to be detected to move from the input end of the conveyor device to the output end of the conveyor device, and the lower tube basket is used to receive the glass tube to be detected that falls from the output end of the conveyor device; the shooting device is arranged on one side of the conveyor device, and the shooting device is electrically connected to the terminal device, and the shooting device is used to shoot the end face image corresponding to the glass tube to be detected, and send the end face image corresponding to the glass tube to be detected to the terminal device; the terminal device is used to control the conveyor belt shaft to start and stop rotating, and determine the processing parameters corresponding to the glass tube to be detected according to the end face image corresponding to the glass tube to be detected. Because, in the embodiment of the present application, the detection staff only needs to put the glass tube to be detected at the input end of the lower tube platform and pick up the glass tube that has been detected in the lower tube basket, and the other steps do not require the participation of the detection staff, and the glass tube processing parameter detection system can automatically complete the work of detecting the processing parameters of the glass tube to be detected, so it can effectively reduce the time cost and labor cost consumed in detecting the processing parameters of the glass tube to be detected, thereby effectively improving the detection efficiency.

[0051] Further, such as Figure 2As shown, the fixture device 3 includes: two brackets 31 and a light source device 32, wherein the two brackets 31 are arranged in parallel on the conveyor belt 21, and the light source device 32 is arranged between the two brackets 31 and close to the side of the shooting device 6. In the embodiment of the present application, the two brackets 31 have the same size, and the size of each bracket 31 and the spacing between the two brackets 31 are determined according to the size of the glass tube to be detected, so as to ensure that the two brackets 31 can fix the glass tube to be detected after the glass tube to be detected rolls into the fixture device 3; because when the end face image of the glass tube to be detected is captured by the shooting device 6, the information on the depth of the glass tube to be detected, such as the light in the depth direction, will be shielded, resulting in a darker end face image captured, therefore, it is necessary to set the light source device 32 between the two brackets 31 and close to the side of the shooting device 6, so as to ensure that the brightness of the captured end face image is normal.

[0052] Further, such as Figure 2 As shown, the photographing device 6 comprises: an industrial camera 61 and a high-beam lens 62 ; wherein the high-beam lens 62 is mounted on the industrial camera 61 . In the embodiment of the present application, in order to ensure that the clarity of the end face image obtained by shooting meets the detection requirements, an industrial camera 61 is used in combination with a telephoto lens 62 as the shooting device 6; wherein, in actual use, the chip target surface size, resolution and other parameters of the industrial camera 61 are determined according to the distance between two adjacent fixture devices 3 and the outer circle drawing diameter corresponding to the glass tube to be detected. For example, the outer circle drawing diameter corresponding to the glass tube to be detected is 36 mm, and the distance between two adjacent fixture devices 3 is 35 mm. Therefore, the shooting range of the industrial camera 61 with the telecentric lens should be greater than twice the outer circle drawing diameter corresponding to the glass tube to be detected. At the same time, in order to effectively utilize the space of the conveyor belt 21, the display range of the shot image should be between 70 mm and 105 mm. Combined with the parameters of the telecentric lens, it can be calculated that the resolution of the selected industrial camera 61 should be ≥3 million pixels and ≤10 million pixels, and the chip target surface size should be ≥1 / 3 inch and ≤2 / 3 inch. When the resolution is selected to be low, the actual distance represented by a single pixel is wider, resulting in lower measurement accuracy; when the resolution is selected to be too high, the edge of the glass tube to be inspected in the captured end face image and the background are gradually changing, making it difficult to determine the boundary line between the inner and outer edges of the glass tube to be inspected.

[0053] Further, such as Figure 2As shown, the glass tube processing parameter detection system also includes: a delivery device 7; the delivery device 7 is arranged above the input end of the lower tube platform 1, the delivery device 7 is electrically connected to the terminal device 5, and the delivery device 7 is used to deliver the glass tube to be detected to the input end of the lower tube platform 1. In the embodiment of the present application, in order to ensure that the glass tube to be detected can be accurately delivered at the input end of the lower tube platform 1 according to the preset delivery interval, the delivery device 7 can be controlled by the terminal device 5 to deliver the glass tube to be detected to the input end of the lower tube platform 1. The terminal device 5 sets a timer for the delivery device 7 in advance. After the delivery device 7 is controlled to deliver a glass tube to be detected to the input end of the lower tube platform 1, the timer corresponding to the delivery device 7 is controlled to start timing. When the timer reaches the preset delivery interval, the timer is controlled to be reset, and the delivery device 7 is controlled to deliver the next glass tube to be detected to the input end of the lower tube platform 1.

[0054] Furthermore, the glass tube processing parameter detection system also includes: an alarm device; the alarm device is electrically connected to the terminal device 5, and the alarm device is used to alarm. In the embodiment of the present application, after the terminal device 5 controls the shooting device 6 to shoot the end face image corresponding to the glass tube to be detected, it is determined whether the glass tube to be detected is located within the center range of the end face image. If the glass tube to be detected is located within the center range of the end face image, the terminal device 5 determines the processing parameters corresponding to the glass tube to be detected according to the end face image corresponding to the glass tube to be detected; if the glass tube to be detected is located outside the center range of the end face image, the terminal device 5 controls the alarm device to alarm to remind the staff that the glass tube to be detected is located outside the center range of the end face image, and the end face image corresponding to the glass tube to be detected needs to be re-shot, and the position of the glass tube to be detected is adjusted by controlling the rotation of the conveyor belt shaft 22 until the glass tube to be detected is within the center range of the re-shot end face image, and the processing parameters corresponding to the glass tube to be detected are determined according to the re-shot end face image.

[0055] Furthermore, a platform baffle is provided on any one or both sides of the lower tube platform 1. In the embodiment of the present application, in order to prevent the glass tube to be inspected from rolling down on the lower tube platform 1 and rolling down to the ground to collide and break, it is necessary to provide a platform baffle on any one or both sides of the lower tube platform 1 to prevent the glass tube to be inspected from rolling down to the ground.

[0056] The present application also provides a method for detecting glass tube processing parameters. Figure 1 or Figure 2 The glass tube processing parameter detection system shown in the figure includes: a tube lowering platform, a conveying device, a plurality of fixture devices, a tube lowering basket, a terminal device, a shooting device and a delivery device. The execution subject of the method is the terminal device in the glass tube processing parameter detection. The terminal device can be, but is not limited to, a computer, a laptop computer, a tablet computer, etc. Figure 3 As shown, the method includes:

[0057] 201. After receiving the detection instruction, the glass tube to be detected is placed at the input end of the lower tube platform, and after the target rolling time, the conveyor belt shaft is controlled to start rotating to drive the conveyor belt to transmit.

[0058] When the testing staff needs to test the processing parameters of a batch of glass tubes to be tested with the same size, the testing staff needs to first select a plurality of corresponding fixtures according to the size of the glass tubes to be tested, and set the plurality of fixtures on the conveyor belt. After completing the preparation work, the input device of the staff terminal device sends a test instruction to the terminal device. After receiving the test instruction, the terminal device will control the delivery device to deliver the glass tubes to be tested at the input end of the lower tube platform according to the preset delivery interval, that is, first control the delivery device to deliver the first glass tube to be tested, and after the first glass tube to be tested is delivered to the delivery device, and after the preset delivery interval, control the delivery device to deliver the second glass tube to be tested, and after the second glass tube to be tested is delivered to the delivery device, and after the preset delivery interval, control the delivery device to deliver the third glass tube to be tested...; and, after delivering the first glass tube to be tested and after the target rolling time, the terminal device controls the conveyor belt shaft to start rotating to drive the conveyor belt to transmit.

[0059] Among them, the preset delivery interval time can be but not limited to: 3s, 4s, 5s, etc.; wherein, the target rolling time is the time required for the glass tube to be detected to roll from the input end of the lower tube platform to the output end of the lower tube platform, so that after the first glass tube to be detected is delivered and after the target rolling time, the glass tube to be detected can just roll onto the clamping device at the input end of the conveying device; wherein, since the transmission speed of the conveyor belt is determined according to the preset delivery interval time, the target rolling time, the distance between adjacent clamping devices and the size of the clamping device, it can be ensured that after the conveyor belt is driven, each glass tube to be detected delivered through the input end of the lower tube platform can roll into the corresponding clamping device.

[0060] Furthermore, in the embodiment of the present application, the terminal device needs to pre-calculate the target rolling time corresponding to the glass tube to be detected and the transmission speed corresponding to the conveyor belt, and the specific process is as follows:

[0061] First, the inner circle drawing diameter, outer circle drawing diameter, vertical distance between the input end and output end of the lower tube platform, friction coefficient and placement inclination angle of the lower tube platform corresponding to the glass tube to be tested are substituted into the preset formula to calculate the target rolling time, wherein the preset formula is as follows:

[0062]

[0063] Among them, t is the target rolling time, ω is the angular velocity corresponding to the glass tube to be detected, g is the gravitational acceleration, h is the vertical distance between the input end and the output end of the lower tube platform, r1 is the inner circle drawing diameter corresponding to the glass tube to be detected, r2 is the outer circle drawing diameter corresponding to the glass tube to be detected, α is the angular acceleration corresponding to the glass tube to be detected, m is the mass corresponding to the glass tube to be detected, μ is the friction coefficient corresponding to the lower tube platform, and θ is the placement inclination angle corresponding to the lower tube platform (that is, the angle between the lower tube platform and the horizontal plane).

[0064] Secondly, according to the target rolling time, the preset delivery interval time, the distance between adjacent fixture devices and the distance between brackets corresponding to the fixture devices, the transmission speed corresponding to the conveyor belt is calculated. That is, the specific process is: first calculate the sum of the target rolling time and the preset delivery interval time to obtain the first calculation result, then calculate the sum of the distance between adjacent fixture devices and the distance between brackets corresponding to the fixture devices to obtain the second calculation result, and finally, divide the second calculation result by the first calculation result to obtain the third calculation result. The third calculation result is the transmission speed corresponding to the conveyor belt; wherein, the distance between brackets corresponding to the fixture device is the distance between the two brackets contained in the fixture device.

[0065] The specific process in which the terminal device controls the conveyor belt shaft to start rotating to drive the conveyor belt to transmit is: controlling the conveyor belt shaft to start rotating according to the transmission speed to drive the conveyor belt to transmit according to the transmission speed.

[0066] 202. Control the photographing device to photograph an end face image corresponding to the glass tube to be inspected.

[0067] After the conveyor belt is driven, the conveyor belt can drive the clamping device and the glass tube to be inspected to move from the input end of the conveying device to the output end of the conveying device. During the movement of the clamping device and the glass tube to be inspected, when the clamping device and the glass tube to be inspected move to the shooting range of the shooting device, the terminal device can control the shooting device to shoot the end face of the glass tube to be inspected to obtain the end face image corresponding to the glass tube to be inspected.

[0068] The terminal device may predetermine the shooting interval duration corresponding to the shooting device, so that in this step, the terminal device may control the shooting device to shoot the end surface image corresponding to the glass tube to be inspected according to the shooting interval duration corresponding to the shooting device;

[0069] Specifically, the specific process of the terminal device determining the shooting interval duration corresponding to the shooting device is as follows: dividing the horizontal distance between the shooting device and the input end of the conveying device by the transmission speed corresponding to the conveyor belt to obtain the first shooting interval duration; determining the first calculation result calculated in step 201 as the second shooting interval duration; specifically, the specific process of the terminal device controlling the shooting device to shoot the end surface image corresponding to the glass tube to be detected according to the shooting interval duration corresponding to the shooting device is as follows: the terminal device sets a timer for the shooting device in advance, and after the terminal device controls the conveyor belt shaft to start rotating, controls the timer corresponding to the shooting device to start timing, when the timer reaches the first shooting interval duration, controls the timer to be reset, controls the shooting device to shoot the end surface image corresponding to the first glass tube to be detected, and controls the timer to restart timing, when the timer reaches the second shooting interval duration, controls the timer to be reset, controls the shooting device to shoot the end surface image corresponding to the second glass tube to be detected, and controls the timer to restart timing, when the timer reaches the second shooting interval duration, controls the timer to be reset, controls the shooting device to shoot the end surface image corresponding to the third glass tube to be detected, and controls the timer to restart timing….

[0070] 203. Determine processing parameters corresponding to the glass tube to be inspected according to the end surface image corresponding to the glass tube to be inspected.

[0071] After the terminal device obtains the end face image corresponding to the glass tube to be detected, it can determine the processing parameters corresponding to the glass tube to be detected according to the end face image corresponding to the glass tube to be detected. The specific process is as follows: first, according to the preset rules, multiple preset mask matrices and the end face image, an edge binary image corresponding to the glass tube to be detected is generated, wherein the edge binary image includes a first circular ring composed of multiple first pixel points and a second circular ring composed of multiple second pixel points, the grayscale values ​​of the multiple first pixel points and the multiple second pixel points are 1, and the grayscale values ​​of other pixel points in the edge binary image are 0; secondly, according to each first pixel point The center coordinates of the first circle are determined according to the corresponding coordinates, and the center coordinates of the second circle are determined according to the coordinates corresponding to each second pixel point, wherein the center coordinates of the first circle are the coordinates corresponding to the center point of the first circle in the edge binary image, and the center coordinates of the second circle are the coordinates corresponding to the center point of the second circle in the edge binary image; finally, according to the coordinates corresponding to each first pixel point, the coordinates corresponding to each second pixel point, the center coordinates of the first circle and the center coordinates of the second circle, the inner circle machining diameter, outer circle machining diameter and concentricity deviation value corresponding to the glass tube to be inspected are determined.

[0072] Specifically, in this step, the terminal device generates an edge binary image corresponding to the glass tube to be detected according to preset rules, multiple preset mask matrices and end face images in the following specific process:

[0073] (1) Using multiple preset mask matrices to perform convolution operations on the end face image to obtain an edge image corresponding to the glass tube to be detected.

[0074] Wherein, the plurality of preset mask matrices include a noise reduction mask matrix, a slope mask matrix and an edge mask matrix;

[0075] After the terminal device obtains the end face image corresponding to the glass tube to be detected, it can first use multiple preset mask matrices to perform convolution operations on the end face image to obtain the edge image corresponding to the glass tube to be detected. The specific process is: first, use the noise reduction mask matrix to perform convolution operations on the end face image to obtain the noise reduction image corresponding to the glass tube to be detected; second, use the slope mask matrix to perform convolution operations on the noise reduction image to obtain the slope image corresponding to the glass tube to be detected; finally, use the edge mask matrix to perform convolution operations on the slope image to obtain the edge image corresponding to the glass tube to be detected.

[0076] It should be noted that using a denoising mask matrix to perform convolution operations on the end face image can improve the imaging quality of the end face image and suppress noise points in the end face image; using a slope mask matrix to perform convolution operations on the denoised image can ensure that the overall grayscale of the denoised image is not changed while being sensitive to the grayscale value of the edge of the glass tube in the denoised image, so that the grayscale value of the edge of the glass tube is retained as much as possible, and the grayscale value of the background color is effectively suppressed; using an edge mask matrix to perform convolution operations on the slope image can enhance the grayscale value of the center point of the edge of the glass tube in the slope image.

[0077] It should be noted that the type of convolution operation performed in the above process can specifically be the same convolution operation, that is, using the denoising mask matrix to perform the same convolution operation on the end face image, using the slope mask matrix to perform the same convolution operation on the denoised image, and using the edge mask matrix to perform the same convolution operation on the slope image.

[0078] Among them, the denoising mask matrix is ​​specifically:

[0079]

[0080] The slope mask matrix is ​​specifically:

[0082] The edge mask matrix is ​​specifically:

[0083]

[0084] (2) Generate an edge binary image corresponding to the glass tube to be detected according to the grayscale value corresponding to each pixel in the edge image.

[0085] After the terminal device obtains the edge image corresponding to the glass tube to be detected, it can generate the edge binary image corresponding to the glass tube to be detected according to the grayscale value corresponding to each pixel in the edge image. The specific process is as follows: first, the maximum value of the grayscale values ​​corresponding to each pixel in the edge image is divided by 2 to obtain the target grayscale value; second, the pixel in the edge image whose grayscale value is greater than the target grayscale value is determined as the third pixel, and the pixel in the edge image whose grayscale value is less than or equal to the target grayscale value is determined as the fourth pixel; third, the target image is generated, wherein the multiple images in the target image are The pixel corresponds one-to-one to multiple pixel points in the edge image; finally, the grayscale value of the pixel point corresponding to each third pixel point in the target image is set to 1, and the grayscale value of the pixel point corresponding to each fourth pixel point in the target image is set to 0 to obtain an edge binary image. For example, if the pixel point in the 3rd row and 5th column in the edge image is determined to be the third pixel point, the grayscale value of the pixel point in the 3rd row and 15th column in the target image is set to 1, and if the pixel point in the 5th row and 5th column in the edge image is determined to be the fourth pixel point, the grayscale value of the pixel point in the 5th row and 5th column in the target image is set to 0….

[0086] Specifically, in this step, the terminal device determines the coordinates of the center of the first circle according to the coordinates corresponding to each first pixel point, and determines the coordinates of the center of the second circle according to the coordinates corresponding to each second pixel point. The specific process is as follows:

[0087] (1) For any pixel point in the edge binary image, the distance from the pixel point to each first pixel point is calculated according to the coordinates corresponding to the pixel point and the coordinates corresponding to each first pixel point, and the maximum value among the calculated multiple distances is determined as the first maximum distance corresponding to the pixel point, so that the first maximum distance corresponding to each pixel point in the edge binary image can be determined; the pixel point corresponding to the minimum value among the determined multiple first maximum distances is determined as the center point corresponding to the first circular ring, and the coordinates corresponding to the center point are determined as the center coordinates corresponding to the first circular ring;

[0088] (2) For any pixel point in the edge binary image, the distance from the pixel point to each second pixel point is calculated according to the coordinates corresponding to the pixel point and the coordinates corresponding to each second pixel point, and the maximum value among the calculated multiple distances is determined as the second maximum distance corresponding to the pixel point, so that the second maximum distance corresponding to each pixel point in the edge binary image can be determined; the pixel point corresponding to the minimum value among the determined multiple second maximum distances is determined as the center point corresponding to the second circular ring, and the coordinates corresponding to the center point are determined as the center coordinates corresponding to the second circular ring.

[0089] It should be noted that for a plane containing a circle, when a point in the plane is outside the circle, the maximum distance from the point to the circle is the shortest distance from the point to the circle plus the diameter of the circle; when a point in the plane is on the circle, the maximum distance from the point to the circle is the diameter of the circle; when a point in the plane is inside the circle and not at the center of the circle, the maximum distance from the point to the circle is the distance from the point to the center of the circle plus the radius of the circle; when a point in the plane is at the center of the circle, the maximum distance from the point to the circle is the radius of the circle. Therefore, after determining the maximum distance from each point in the plane to the circle, the point corresponding to the minimum value of the multiple maximum distances is the center of the circle.

[0090] Specifically, in this step, the terminal device determines the coordinates of the center of the first circle according to the coordinates corresponding to each first pixel point, and determines the coordinates of the center of the second circle according to the coordinates corresponding to each second pixel point. The specific process is as follows:

[0091] (1) For any pixel point in the edge binary image, the distance from the pixel point to each first pixel point is calculated according to the coordinates corresponding to the pixel point and the coordinates corresponding to each first pixel point, and the maximum value among the calculated multiple distances is determined as the first maximum distance corresponding to the pixel point, so that the first maximum distance corresponding to each pixel point in the edge binary image can be determined; the pixel point corresponding to the minimum value among the determined multiple first maximum distances is determined as the center point corresponding to the first circular ring, and the coordinates corresponding to the center point are determined as the center coordinates corresponding to the first circular ring;

[0092] (2) For any pixel point in the edge binary image, the distance from the pixel point to each second pixel point is calculated according to the coordinates corresponding to the pixel point and the coordinates corresponding to each second pixel point, and the maximum value among the calculated multiple distances is determined as the second maximum distance corresponding to the pixel point, so that the second maximum distance corresponding to each pixel point in the edge binary image can be determined; the pixel point corresponding to the minimum value among the determined multiple second maximum distances is determined as the center point corresponding to the second circular ring, and the coordinates corresponding to the center point are determined as the center coordinates corresponding to the second circular ring.

[0093] It should be noted that for a plane containing a circle, when a point in the plane is outside the circle, the maximum distance from the point to the circle is the shortest distance from the point to the circle plus the diameter of the circle; when a point in the plane is on the circle, the maximum distance from the point to the circle is the diameter of the circle; when a point in the plane is inside the circle and not at the center of the circle, the maximum distance from the point to the circle is the distance from the point to the center of the circle plus the radius of the circle; when a point in the plane is at the center of the circle, the maximum distance from the point to the circle is the radius of the circle. Therefore, after determining the maximum distance from each point in the plane to the circle, the point corresponding to the minimum value of the multiple maximum distances is the center of the circle.

[0094] Specifically, in this step, the terminal device determines the concentricity deviation value corresponding to the glass tube to be tested according to the center coordinates of the first circle and the center coordinates of the second circle as follows:

[0095] Firstly, according to the center coordinates corresponding to the first circular ring and the center coordinates corresponding to the second circular ring, the image concentricity deviation value corresponding to the glass tube to be detected is calculated, that is, according to the coordinates of the center point of the first circular ring in the edge binary image (that is, the center coordinates corresponding to the first circular ring) and the coordinates of the center point of the second circular ring in the edge binary image (that is, the center coordinates corresponding to the second circular ring), the distance between the center point of the first circular ring and the center point of the second circular ring in the edge binary image is calculated, and the distance is determined as the concentricity deviation value between the first circular ring and the second circular ring (that is, the image concentricity deviation value corresponding to the glass tube to be detected); secondly, according to the pixel size corresponding to the edge binary image and the image concentricity deviation value, the concentricity deviation value corresponding to the glass tube to be detected is determined, that is, the image concentricity deviation value is multiplied by the pixel size corresponding to the edge binary image to obtain the concentricity deviation value corresponding to the glass tube to be detected.

[0096] Furthermore, in an embodiment of the present application, after the terminal device controls the shooting device to shoot the end face image corresponding to the glass tube to be detected, it is also necessary to determine whether the glass tube to be detected is located within the center range of the end face image; if the glass tube to be detected is located within the center range of the end face image, the terminal device can directly use the method described in the above step 203 to determine the corresponding processing parameters of the glass tube to be detected according to the end face image corresponding to the glass tube to be detected; if the glass tube to be detected is located outside the center range of the end face image, the terminal device needs to adjust the position of the glass tube to be detected by controlling the rotation of the conveyor belt shaft, and control the shooting device to re-shoot the end face image corresponding to the glass tube to be detected until the glass tube to be detected is within the center range of the re-shot end face image. At this time, it is necessary to determine the corresponding processing parameters of the glass tube to be detected according to the re-shot end face image, and the specific process can refer to the method described in the above step 203. Among them, the central area of ​​the end face image is the area between 1 / 4 and 3 / 4 of the end face image in the horizontal direction. When the center of the first ring and the center of the second ring corresponding to the glass tube to be detected are both within the central area of ​​the end face image, it can be determined that the glass tube to be detected is located within the central range of the end face image. When the center of the first ring and / or the center of the second ring corresponding to the glass tube to be detected are outside the central area of ​​the end face image, it can be determined that the glass tube to be detected is located outside the central range of the end face image, but not limited to this.
