[0026] The present application embodiment provides a mobile plate immersion ultrasonic detection method. In one embodiment, please refer to Figure 1 , Figure 1 The present invention provides a flow chart of a mobile plate water immersion ultrasonic detection method. The method can be implemented by a computer program, which can be integrated into an application or run as an independent tool application. The method can also be implemented by a single-chip microcomputer or run on a mobile plate water immersion ultrasonic detection system based on a von Neumann system. Specifically, the method can include the following steps:

[0027] Step 101: Obtain the plate length, plate width and installation position of the plate to be inspected.

[0028] Specifically, before the mobile plate immersion ultrasonic testing begins, it is necessary to obtain the basic information of the plate to be tested, including the length, width and installation position of the plate, so as to calculate the moving trajectory and scanning parameters of the ultrasonic probe. The size of the plate to be tested can be detected in real time by sensors, or the length and width data of the plate can be extracted from the plate production information; the spatial installation position of the plate can be detected by equipment such as laser rangefinders, or the position coordinate information of the plate can be calculated through image processing. After obtaining this information, the system can determine the scanning range according to the specific size specifications of the plate, and set the initial position, scanning height, scanning angle, etc. of the ultrasonic probe based on the installation position parameters of the plate, so as to plan the mobile ultrasonic scanning plan in a targeted manner, so that the ultrasonic wave can fully cover the surface of the plate to be tested and detect various defect information inside the plate.

[0029] Step 102: Based on the plate length, plate width and preset scanning overlap ratio, determine the longitudinal axis movement distance of the ultrasonic probe after a single ultrasonic detection, and adjust the scanning posture of the ultrasonic probe according to the installation position and the initial position of the ultrasonic probe to obtain an adjusted ultrasonic probe.

[0030] Among them, the preset scanning overlap ratio refers to the ratio of the overlapping area between two adjacent scans. In the embodiment of the present application, it can be understood as the ratio of the preset overlapping length between the scanning trajectories to the single effective scanning length, which is used to ensure that there is a certain repeated scanning range between different scanning intervals during the mobile scanning process.

[0031] An ultrasonic probe refers to a sensor that can transmit and receive ultrasonic waves. In the embodiments of the present application, it can be understood as an ultrasonic sensor equipped with a piezoelectric crystal, which is used to emit high-frequency sound waves to the object being detected and receive echo signals reflected from the object.

[0032] The longitudinal axis movement distance refers to the distance that the ultrasonic probe needs to move in the longitudinal axis direction after completing a transverse scan. In the embodiment of the present application, it can be understood as the distance that the ultrasonic probe moves downward from the current scan end position to the next scan start position. It is used to realize the gradual movement of the ultrasonic probe in the longitudinal direction according to a predetermined scanning path, thereby covering the entire surface of the plate to be inspected and realizing comprehensive detection.

[0033] The scanning posture refers to the position and direction state of the ultrasonic probe during scanning. In the embodiments of the present application, it can be understood as the telescopic height and rotation angle of the ultrasonic probe, which is used to adjust the relative position relationship between the ultrasonic probe and the plate to be tested so that the ultrasonic wave can be incident vertically on the surface of the plate to obtain a better quality scanning result.

[0034] Specifically, after obtaining the size and position information of the plate, it is necessary to calculate the longitudinal movement distance of the ultrasonic probe and adjust the scanning posture of the probe. The longitudinal movement distance is calculated to realize the grid scanning of the ultrasonic probe. It is calculated according to the length, width and preset scanning overlap ratio of the plate, which can ensure that there are no gaps or excessive repetitions between the scanning tracks, thereby improving the scanning efficiency. The scanning posture is adjusted to make the ultrasonic beam incident vertically on the surface of the plate. First, the height that the probe needs to be adjusted is calculated according to the installation position of the plate, and then the rotation angle of the probe is set according to the inclination angle of the plate surface to ensure that the direction of the probe's sound beam is perpendicular to the surface of the plate. Through this calculation and adjustment, a mobile scanning scheme designed for a specific plate can be obtained, including the spacing of the scanning track and the posture information of the probe. This ensures that the obtained ultrasonic image is clear and complete, providing a reliable data source for subsequent image analysis and defect detection.

[0035] Based on the above embodiment, as an optional embodiment, in step 102: determining the longitudinal axis movement distance of the ultrasonic probe after a single ultrasonic detection based on the plate length, plate width and a preset scanning overlap ratio, this step may also include the following steps:

[0036] Step 201: Obtain a reference scanning width of the ultrasonic probe; determine the number of transverse scanning times of the ultrasonic probe according to the width of the plate and the reference scanning width of the ultrasonic probe.

[0037] Among them, the reference scanning width refers to the scanning width that the ultrasonic probe can effectively cover in one scan. In the embodiment of the present application, it can be understood as the effective width when the sound beam of the ultrasonic probe reaches a certain intensity in the scanning direction, which is used to determine the single scanning range of the ultrasonic probe.

[0038] The number of transverse scans refers to the total number of scans that the ultrasonic probe needs to perform in the transverse direction, that is, the horizontal direction, when performing a grid scan on the plate to be inspected. In the embodiment of the present application, it can be understood as the total number of transverse scans of the ultrasonic probe required to cover the entire width of the plate, which is used to determine the longitudinal movement distance and scanning trajectory.

[0039] Specifically, in order to calculate the longitudinal movement distance of the ultrasonic probe, it is necessary to first determine the parameters of the transverse scan. Specifically, the reference scanning width of the ultrasonic probe is first obtained, which can be found in the technical specification table of the probe, indicating its single effective scanning width. Then, according to the width of the plate to be detected and the reference width obtained in the previous step, the number of transverse scans required can be calculated. The calculation method is to divide the plate width by the reference scanning width to get the number of transverse scans. This is done to reasonably plan the scanning trajectory to ensure full coverage of the entire plate. Knowing the reference width and the number of transverse scans, the longitudinal movement distance can be calculated so that there is neither gap nor excessive overlap between each transverse scan. The reference scanning width can be directly called by the control system, and the calculation of the number of transverse scans can be completed automatically. This can improve the efficiency of scanning trajectory planning and ensure the automation of mobile ultrasonic testing.

[0040] Step 202: Calculate the product of the plate length and the preset scanning overlap ratio to obtain the overlap length, and subtract the overlap length from the plate length to obtain the effective detection length.

[0041] The overlapping length refers to the length of repeated scanning in the longitudinal direction between two adjacent scanning trajectories in mobile ultrasonic scanning. In the embodiment of the present application, it can be understood as the longitudinal repeated scanning distance calculated according to the preset scanning overlap ratio, which is used to ensure the continuity of the scanning and avoid missed detection.

[0042] The effective detection length refers to the effective scanning length of a single longitudinal movement scan of the ultrasonic probe. In the embodiments of the present application, it can be understood as the actual detection length of each scan after deducting the overlap length, which is used to calculate the longitudinal movement distance of the ultrasonic probe.

[0043] Specifically, in order to calculate the longitudinal movement distance of the ultrasonic probe, it is necessary to first calculate the effective detection length of the longitudinal scan. According to the preset scanning overlap ratio and the length of the plate, the overlapping length in the longitudinal direction is calculated by multiplying the two. Subtract the overlapping length calculated in the previous step from the total length of the plate to obtain the effective detection length of each longitudinal scan. The purpose of calculating the effective detection length in this way is to reasonably design the scanning spacing. Setting the overlapping length can ensure that there are repeated areas in different scanning intervals during the mobile scanning process, avoid missed detection, and improve the reliability of the detection. The calculation process can be automatically completed by the system, and the length parameters can be collected in real time. The calculation results will be used to subsequently determine the longitudinal movement distance to achieve automated mobile ultrasonic scanning detection.

[0044] Step 203: Divide the effective detection length by the number of transverse scans to obtain the longitudinal axis movement distance of the ultrasonic probe after a single ultrasonic detection.

[0045] Specifically, the effective detection length is divided by the number of scans required in the horizontal direction, and the result is the distance the ultrasonic probe needs to move in the longitudinal direction each time. The purpose of calculating the longitudinal axis movement distance in this way is to reasonably design the scanning trajectory so that the longitudinal distance between each horizontal scan has neither gaps nor excessive repetitions, thereby achieving full coverage scanning. The calculation process can be automatically completed by the control system. The obtained moving distance will be applied to the control system of the ultrasonic probe to guide it to move according to the set scanning trajectory, which can ensure that the trajectory of the mobile ultrasonic scanning is reasonable and effective, avoid missed detection, and improve the efficiency of automated detection.

[0046] Based on the above embodiment, as an optional embodiment, in step 102: adjusting the scanning posture of the ultrasonic probe according to the installation position and the initial position of the ultrasonic probe, this step may also include the following steps:

[0047] Step 204: Based on the distance between the installation position and the reference scanning plane, the installation height of the plate to be detected is determined, and the installation position is compared with the initial position of the ultrasonic probe to determine the inclination angle between the ultrasonic probe and the plate to be detected.

[0048] Among them, the installation height refers to the height position of the surface of the plate to be detected relative to the preset reference scanning plane. In the embodiment of the present application, it can be understood as the distance between the elevation position of the plate surface and the height of the reference plane, which is used to determine the height to which the ultrasonic probe needs to be adjusted so that its ultrasonic beam can be incident vertically on the surface of the plate.

[0049] The tilt angle refers to the angle formed between the ultrasonic incident direction of the ultrasonic probe and the normal direction of the surface of the plate to be detected. In the embodiment of the present application, it can be understood as the relative tilt angle between the probe and the surface of the plate, which is used to determine the angle of the probe that needs to be rotated to make the ultrasonic wave vertically incident on the surface of the plate.

[0050] Specifically, in order to achieve the best scanning effect of the ultrasonic probe, it is necessary to adjust the relative position relationship between the probe and the plate. First, the system will obtain the installation position coordinates of the plate, and calculate the specific installation height of the plate surface according to the preset reference scanning plane height. Then, the system will obtain the initial position coordinates of the ultrasonic probe and compare them with the installation position of the plate to calculate and determine the tilt angle that the ultrasonic probe needs to be adjusted, that is, the angle between the probe beam and the normal direction of the plate. This is done to obtain the precise height of the plate and the relative tilt relationship between the two components through calculation, so as to guide the robotic arm to adjust the height and angle of the probe as needed, ensure that the ultrasonic beam is incident vertically on the surface of the plate, obtain the best quality scanning image, and avoid image mismatch. The calculation process can be automatically completed by the control system, and the control parameters are output to accurately adjust the scanning posture of the probe, thereby improving the adaptability of mobile ultrasonic detection.

[0051] Step 205: According to the installation height, the telescopic height of the ultrasonic probe is adjusted so that the distance between the ultrasonic probe and the surface of the plate to be detected is a preset distance.

[0052] Among them, the telescopic height refers to the adjustable height range of the ultrasonic probe in the vertical direction. In the embodiment of the present application, it can be understood as the adjustable height range of the ultrasonic probe installed on the robotic arm, which is used to adjust the position height of the ultrasonic probe according to the calculated plate installation height so that it maintains an optimal relative distance relationship with the plate.

[0053] Specifically, in order to allow ultrasonic waves to be incident vertically, the height of the ultrasonic probe needs to be adjusted according to the calculated installation height of the plate. The telescopic height of the ultrasonic probe is adjusted using a probe clamping device with a microscope-like structure so that the probe maintains a preset distance from the surface of the plate, which ensures that the probe beam is in a vertical incidence state. Adjustment is made based on the installation height because plates of different thicknesses have different surface heights. In order to adapt to different plates and ensure vertical incidence, the height of the probe needs to be matched. The control system outputs a control signal to drive the robotic arm to accurately adjust the height of the probe. This ensures that during mobile ultrasonic detection, the relative position relationship between the probe and the plate is appropriate, and the ultrasonic wave of the probe can be incident vertically on the surface of the plate to obtain the best quality detection image.

[0054] Step 206: Based on the tilt angle, adjust the deflection angle of the ultrasonic probe so that the sound beam direction of the ultrasonic probe is perpendicular to the surface of the plate to be inspected.

[0055] Among them, the sound beam direction refers to the direction of propagation of the ultrasonic beam emitted by the ultrasonic probe. In the embodiments of the present application, it can be understood as the direction angle of emission and propagation of the ultrasonic beam of the ultrasonic probe, which is used to indicate the ultrasonic energy propagation direction and detection direction of the probe.

[0056] Specifically, in order to achieve vertical incidence of ultrasonic waves, it is necessary to adjust the direction of the ultrasonic probe to be perpendicular to the surface of the plate. The system will determine the angle that needs to be adjusted based on the pre-calculated inclination angle between the probe and the plate. Then, the deflection angle of the ultrasonic probe is controlled so that the direction of the probe's sound beam coincides with the normal direction of the plate surface to maintain a vertical relationship. This is done to correct the probe tilt caused by the position of the plate. By controlling the deflection angle to adjust the probe direction, it is ensured that the ultrasonic beam is incident on the plate surface at a 90-degree incident direction. This can ensure that the ultrasonic wave is always incident vertically on the plate during mobile scanning, avoid image distortion, and improve the detection effect. The calculation and control process is automatically completed by the system, so that mobile ultrasonic detection can achieve automatic adaptation to plates of different shapes and positions.

[0057] Step 103: According to the longitudinal axis moving distance and the preset scanning rule, the adjusted ultrasonic probe is controlled to perform multiple ultrasonic tests on the plate to be tested to obtain multiple ultrasonic images.

[0058] Among them, the preset scanning rules refer to the rules of the order and path in which the ultrasonic probe scans during the mobile ultrasonic scanning process. In the embodiment of the present application, it can be understood as the scanning mode rule that the ultrasonic probe first scans horizontally and then moves vertically, which is used to guide the ultrasonic probe to scan the plate to be inspected in an orderly manner in a segmented, crawling, etc.

[0059] Ultrasonic testing refers to the process of using ultrasonic waves to perform non-contact internal flaw detection on an object. In the embodiments of the present application, it can be understood as using an ultrasonic probe to emit high-frequency sound waves and receive echo signals to scan the plate to be inspected layer by layer to obtain image information of the internal structure or defects of the plate.

[0060] An ultrasonic image refers to a visual image that reflects the internal structure or tissue of the inspection object formed after ultrasonic testing. In the embodiments of the present application, it can be understood as a two-dimensional grayscale image formed by processing the reflected signal received by the probe after ultrasonic testing of the plate, which is used to observe the internal condition of the plate and identify defects.

[0061] Specifically, after calculating the longitudinal axis movement distance of the ultrasonic probe, the ultrasonic probe can be controlled to perform multiple inspections on the plate according to this distance and the preset scanning rules. This is done to obtain ultrasonic images of multiple coverage surfaces of the entire surface of the plate for comprehensive inspection. The control system controls the ultrasonic probe to first perform a horizontal scan according to the preset scanning rules to obtain the first scanning image; then controls the probe to move down to the next scanning position with the calculated longitudinal axis distance; repeats this movement to finally obtain ultrasonic images of multiple segments of the plate. In this way, multiple scans with staggered cracks can ensure complete coverage of the entire plate, avoid blind spots or missed inspection areas, and improve the comprehensiveness and reliability of the inspection. The multiple ultrasonic images obtained will be subsequently spliced, analyzed and processed to identify defects and cracks inside the plate.

[0062] Based on the above embodiment, as an optional embodiment, in step 103: according to the longitudinal axis moving distance and the preset scanning rule, the adjusted ultrasonic probe is controlled to perform multiple ultrasonic tests on the plate to be tested to obtain multiple ultrasonic images. This step may also include the following steps:

[0063] Step 301: Based on the preset scanning rules, the ultrasonic probe is controlled to scan the plate to be inspected along the horizontal axis direction to obtain an ultrasonic image. After each scanning operation in the horizontal axis direction is completed, the ultrasonic probe is controlled to move along the vertical axis direction by the vertical axis movement distance, and the position of the ultrasonic probe after movement is used as the starting position of the next scanning operation.

[0064] Specifically, in order to achieve comprehensive inspection of the entire plate, it is necessary to control the ultrasonic probe to move and scan according to the preset scanning rules. First, the system controls the ultrasonic probe to start scanning the plate along the horizontal axis according to the preset scanning rules. After completion, an ultrasonic image of the plate at that position can be obtained. Then, after each horizontal scan, the system controls the ultrasonic probe to move downward along the longitudinal axis by the calculated moving distance, and uses the moved position as the starting position of the next scan. This is done in order to achieve complete coverage inspection of the entire plate through multiple staggered scans, avoid missed inspection areas, and improve the comprehensiveness of the inspection. The control of the scanning path is automatically completed by the system, and the horizontal and vertical scans are performed one by one according to the set rules. The moving distance is accurately matched to avoid duplication or omission, thereby improving the inspection efficiency.

[0065] Based on the above embodiment, as an optional embodiment, in step 301: based on a preset scanning rule, the ultrasonic probe is controlled to scan the plate to be inspected along the horizontal axis direction. This step may also include the following steps:

[0066] Step 311: Obtain the lateral boundary position of the plate to be inspected and the starting position of the ultrasonic probe; use the lateral boundary position as the end position of the scanning operation, and control the ultrasonic probe to move at a constant speed from the starting position to the end position, while performing ultrasonic transmission and ultrasonic reception.

[0067] The lateral boundary position refers to the position coordinate of the end point of the lateral dimension of the plate to be detected, which can be understood as the end point of the lateral length of the plate in the embodiment of the present application, and is used to determine the end position of a lateral scan.

[0068] Specifically, in order to control the ultrasonic probe to complete a lateral scanning movement, it is necessary to locate the starting and ending positions of the scan and control the probe to move at a uniform speed. The system first obtains the lateral boundary position of the plate to be detected and determines it as the end position of this scan. Then the system obtains the current starting position coordinates of the ultrasonic probe. After these two coordinates are used as the starting and ending positions for controlling the probe scan, the system controls the probe to move uniformly from the starting position to the predetermined end position at a constant speed, while transmitting ultrasonic pulses and receiving echoes. This is done to accurately control the scanning range and movement process of a lateral scan, so that the probe can complete a lateral scan of the plate at a continuous and stable speed, and obtain complete ultrasonic information in this direction segment. The control and acquisition processes are automatically completed by the system, without the need for manual operation, thereby improving detection efficiency.

[0069] Step 321: When the ultrasonic probe reaches the end position, the ultrasonic probe is controlled to stop and turn, and move at a constant speed from the end position to the start position, while performing ultrasonic transmission and ultrasonic reception.

[0070] Specifically, in order to achieve bidirectional scanning of the same scanning path, it is necessary to turn around and return after reaching the end position. The system continuously monitors the position of the probe to determine whether it has reached the predetermined transverse scanning end position. When the probe position reaches the end position, the system controls the probe to immediately stop the transverse movement and quickly turn the direction 180 degrees. Then, the system controls the probe to start from the stopped end position and move at a constant speed to the starting position in the opposite direction, while continuing to transmit and receive ultrasound. In this way, bidirectional scanning of the same scanning path can be completed, which is conducive to improving the integrity of the scan and avoiding the problem of missed detection that may be caused by unidirectional scanning.

[0071] Step 302: Repeat the scanning operation until the starting position reaches the bottom of the plate to be inspected, and obtain multiple ultrasonic images.

[0072] Specifically, in order to achieve complete detection coverage of the entire plate, it is necessary to repeat the scanning operation until the probe position reaches the bottom of the plate. The system controls the ultrasonic probe to alternately perform lateral scanning and longitudinal movement according to preset rules. After each lateral scan and longitudinal movement, the probe position drops a longitudinal movement distance. The system will determine whether the current probe position has reached the bottom of the plate. If it has not yet reached the bottom, it will continue to control the probe to perform a scanning operation in a loop. The repeated scanning is to obtain ultrasonic images of all parts of the plate through the overall coverage of the scanning track, to ensure the comprehensiveness of the detection and avoid missed detection. After the repeated scanning is completed, multiple ultrasonic images covering different areas of the plate can be obtained to provide data for subsequent image processing and analysis.

[0073] Based on the above embodiment, as an optional embodiment, in step 103: controlling the adjusted ultrasonic probe to perform multiple ultrasonic tests on the plate to be tested, this step may also include the following steps:

[0074] Step 303: a water jacket is provided below the installation position of the ultrasonic probe, wherein the water jacket comprises a water inlet and a water outlet; water is injected into the water jacket through the water inlet, and the water level in the water jacket is monitored.

[0075] The water jacket refers to a ring-shaped container placed directly below the ultrasonic probe. It is made of acrylic or other similar materials and has a certain height to leave space. The water jacket has a water inlet at the top and a water outlet at the bottom. The ultrasonic probe mounting device will be higher than the water jacket as a whole to leave space.

[0076] When in use, water is injected into the water jacket through the water inlet, and the water will fill the water jacket and play a coupling role. When the water volume reaches a certain height, the excess water will flow out from the water outlet. In this way, the water level in the water jacket can be kept at the optimal state. The water jacket is sealed with materials such as tape to prevent water from overflowing. The water stored in the water jacket can acoustically couple the ultrasonic probe and the plate to be tested. After the water flow is sprayed onto the surface of the plate, it is conducive to the propagation and detection of ultrasonic waves.

[0077] Specifically, in order to achieve good sound beam transmission between the ultrasonic probe and the detected object, it is necessary to set up a water jacket and monitor the water level in real time. An annular water jacket device is set directly below the ultrasonic probe, and the water jacket is provided with a water inlet and a water outlet. Then water is injected into the water jacket through the water inlet until the water level reaches a preset height. It is also necessary to set up a water level monitoring device to monitor and feedback the water level information in the water jacket in real time. The purpose of monitoring the water level is to replenish the water in time so that the water level in the water jacket is maintained at the optimal state to avoid abnormal situations such as drying up or overflowing. The setting of the water jacket greatly improves the portability and applicable scenarios of the entire mobile ultrasonic detection system. It is no longer limited to a fixed pool site and can flexibly respond to more diverse detection needs.

[0078] Step 304: When the water level reaches a preset height, the water outlet is opened to inject water into the surface of the plate to be inspected.

[0079] Specifically, in order to inject water into the surface of the plate in real time during the detection process, it is necessary to monitor the water level of the water jacket and open the water outlet. The system continuously monitors the water level data in the water jacket. When the water level rises to a preset height, the control logic determines that the water volume is sufficient, and then opens the water outlet at the bottom of the water jacket. After the water outlet is opened, the water in the water jacket will flow out from the water outlet and aim at the surface of the plate to be detected for water injection. Such real-time water injection is to maintain sufficient water on the surface of the plate so that the ultrasonic wave can smoothly propagate through the water to the surface of the plate, and then reflect from the plate back to the probe. By controlling the opening and closing of the water outlet, the water level in the water jacket can be automatically maintained, and continuous and uninterrupted water injection can be achieved for the plate during the detection process. The water injection method of the water jacket improves the adaptability of mobile ultrasound to plates with various surface conditions.

[0080] Step 104: Determine the defect detection result of the plate to be detected by combining the ultrasonic images.

[0081] Among them, the defect detection result refers to the result data reflecting the defects existing in the plate to be inspected, which is obtained by analyzing and integrating multiple ultrasonic images. In the embodiment of the present application, it can be understood as a test report containing information such as the defect location, shape, size, etc. generated after ultrasonic scanning of the plate, which is used to evaluate the quality level of the plate.

[0082] Specifically, in order to comprehensively utilize multiple ultrasonic images to complete the inspection of the entire plate, it is necessary to analyze and verify each ultrasonic image to obtain the final inspection result of the plate. The system first performs image processing on the multiple ultrasonic images obtained by scanning to extract areas where defects may exist. Then, the system will match the same physical positions in different ultrasonic images, perform correlation analysis on the same positions of each ultrasonic image, and determine whether there are common suspected defect areas. This is done to make full use of the multi-angle information provided by multiple ultrasonic images, thereby improving the accuracy and reliability of the inspection. Finally, the system combines the analysis results of multiple ultrasonic images to obtain an overall inspection report for the plate, identifying the location, shape and other information of all detected defects. The entire inspection and analysis process is automated to avoid omissions in manual work.

[0083] Based on the above embodiment, as an optional embodiment, in step 104: combining each ultrasonic image to determine the defect detection result of the plate to be detected, this step may also include the following steps:

[0084] Step 401: performing image preprocessing on each ultrasonic image to obtain a target image after the preprocessing of each ultrasonic image.

[0085] Specifically, in order to improve the accuracy of subsequent image analysis, the original ultrasound images need to be preprocessed first. The system will perform image processing operations such as denoising and contrast enhancement on multiple original ultrasound images obtained by scanning. After preprocessing, an ultrasound image target image with higher clarity and reduced noise can be obtained. This is because there is often noise interference in the original ultrasound image, and directly identifying defects on it will lead to false alarms. Image preprocessing can improve image quality and enhance the contrast of suspected defect areas, which is conducive to the subsequent accurate extraction of defect features.

[0086] Step 402: Compare each target image with a preset defect image feature to determine the defect position and defect shape of the plate to be inspected, and use the defect position and defect shape as the defect detection result of the plate to be inspected.

[0087] Among them, the defect position and defect shape refer to the specific positioning coordinates of defects in the plate and the shape contour of the defect area detected by ultrasonic image analysis. In the embodiments of the present application, they can be understood as the position coordinates and shape characteristics of the plate defects determined after mobile ultrasonic scanning, which are used to intuitively reflect and locate internal defects in the plate as a basis for quality assessment.

[0088] Specifically, in order to detect defects in the plate, it is necessary to judge suspected defects in the ultrasonic image by comparing with standard features. The system compares the preprocessed target ultrasonic image with the preset standard image features of various defects one by one. The comparison method includes matching analysis of image information such as shape, edge, and contrast. When there is an area in the target image whose features are highly matched with the standard defect features, it is determined that there is a defect of the corresponding type at that location. Finally, the system can statistically obtain the specific location coordinates and defect categories of all defects in the plate and generate a defect detection report. In this way, by comparing and judging with the standard feature library, the accuracy and reliability of defect detection can be improved, and the entire detection and analysis process is automated, avoiding errors in manual interpretation.
