In addition, some or all of the modules may be selected according to actual needs to achieve the purpose of the present application.

[0027] Please refer to Figure 1 The present invention provides a quality inspection method for water conservancy construction projects, comprising: S101: obtaining a basic image of the current dam body, preprocessing the basic image, establishing an image recognition model, and determining whether the current dam body has cracks or water stains through the image recognition model; Among them, the presence of cracks or water stains can directly confirm that there is a problem with the current dam body and it is unqualified. The presence of water stains needs to be determined whether it is leakage of the dam body or other interference. Since detection on rainy days will cause greater interference, in this embodiment, the situation of detection on rainy days is ignored.

[0028] S102: if there are cracks, output the result that the current water conservancy construction project is unqualified; if there are only water stains, determine whether the current water stains are leakage of the dam body; if so, output the result that the current water conservancy construction project is unqualified; if not, set the next image acquisition time interval and acquisition times; In this embodiment, as long as cracks appear, it is judged as unqualified, including the case where cracks and water stains appear at the same time. If only water stains appear, further judgment is required.

[0029] The acquisition of basic images can be for photo and video monitoring: regularly take photos or videos of the dam body to observe the changes in the appearance of the dam body; or use tools such as levels and total stations to perform physical measurements of the dam body.

[0030] Of course, satellite images can also be used to obtain information about the dam and its surrounding environment, and regional analysis and large-scale monitoring can be carried out. Unmanned aerial vehicles (UAVs) can be used to collect high-resolution images, which are suitable for detailed observation of the dam and its surroundings.

[0031] Terrestrial laser scanning: Use a laser scanner to obtain a high-precision 3D model of the dam body, and analyze the dam body's geometry and deformation through point cloud data.

[0032] S103: obtaining a number of basic images by setting the next image acquisition time interval and the number of acquisition times, judging whether the current dam body is deformed by the number of basic images, and obtaining a number of groups of basic data of the dam body at different periods, if there is no deformation, entering the first detection process, if there is deformation, entering the second detection process; In this embodiment, if deformation occurs, it can also be judged as unqualified. This solution gradually determines whether there is deformation based on the results of the above steps, from simple detection methods to complex detection methods. On the one hand, it simplifies the detection steps, and on the other hand, it can obtain more accurate results.

[0033] S104: The first detection process includes establishing a dam body use prediction simulation model, and outputting a result of whether the current dam body is qualified through a number of sets of basic data in different periods and the dam body use prediction simulation model; S105: The second detection process includes establishing a dam body quality alarm model, outputting an evaluation value through current basic data and the dam body quality alarm model, and setting an evaluation value threshold, and outputting a general alarm or a serious alarm result for the current dam body quality through the evaluation value and the evaluation value threshold.

[0034] In this embodiment, a general alarm is an alarm level that can be urgently repaired, and a severe alarm is an alarm level that cannot be salvaged. In this way, when the unqualified situation is known, more effective information can be further provided to the staff for response.

[0035] The method provided by the invention mainly includes judging whether the current dam body has cracks or water stains through an image recognition model; obtaining a number of basic images through the set time interval and number of acquisitions for the next image acquisition, judging whether the current dam body is deformed through the several basic images, and obtaining the basic data of the current dam body. If it is not deformed, the first detection process is entered, and if it is deformed, the second detection process is entered. Through the above method of the present invention, a deeper judgment can be made again on the result of judging whether the current dam body is qualified, and the judged result can be analyzed. Whether it is qualified or unqualified, more subsequent content can be obtained through the two selected detection processes for staff to analyze, so that more subsequent results can be output in combination with the current situation to make the final detection result more accurate.

[0036] In an exemplary embodiment of the present invention, preprocessing the base image includes: Read the color data of the base image and convert each pixel from the RGB color space to a grayscale value; Assigning the grayscale value to the new image matrix to generate a first image containing only grayscale information; Select the size and standard deviation of the Gaussian filter, and generate a Gaussian kernel based on the size and standard deviation; The first image is convolved with a Gaussian kernel, each pixel in the image is traversed, and the current pixel and its surrounding pixels are weighted averaged by the Gaussian kernel to output a second image.

[0037] The second image is a preprocessed basic image.

[0041] S203: If they overlap, then a plurality of first image features are acquired in a plurality of time periods to determine whether the first image features are reduced. If not, then outputting that the current water stain is a result of leakage of the dam body; if reduced, then outputting that the current water stain is not a result of leakage of the dam body.

[0042] If the water stains are on the dam body, a normal judgment can be made to see if the water stains have changed. If they have shrunk, it means that they are not water stains caused by leakage from the dam body. Not shrinking includes getting bigger or not changing. If they get bigger, there is no need to explain, and leakage must have occurred. Under normal circumstances, water will evaporate on its own, so if it does not change, it means that the leaked water and the evaporated water have reached a balance, and only then will the unchanged situation occur. Therefore, it is also judged that there is leakage in the dam body, and the current water stains are leakage of the dam body.

To obtain the number of times.

[0046] In this embodiment, a variety of factors are comprehensively considered to provide a basis for the interval of the next image acquisition, and combined with some parameters of the dam body, the accuracy and reliability of the results are significantly improved. The integration of various data and variables helps to identify potential risks and optimize decisions, reducing uncertainty. At the same time, it can also achieve more comprehensive analysis, enhance the adaptability and flexibility of the model, make it closer to the actual situation, and support more scientific prediction and planning.

[0047] In an exemplary embodiment of the present invention, judging whether the current dam body is deformed by using a plurality of basic images includes: The ratio of the dam body features to the entire basic image in several basic images is obtained, and a judgment model is established.
