[0030] The working principle of the above technical solution is: at fixed time intervals, P quality reports of the construction site are collected, and these quality reports are numerically processed to form a set S. A monitoring function L(S) is defined, which is used to evaluate the difference between the actual quality report value and the predicted value.

Based on the maximum X value, when the value obtained by the prediction function f(X) is less than the preset quality threshold, a quality warning prompt is generated.

[0031] The beneficial effects of the above technical solution are as follows: by collecting and analyzing historical quality report data, using mathematical methods to solve the monitoring coefficient, and then constructing a prediction function. This prediction function can predict the quality of the future construction site and generate quality warning prompts when necessary, thereby helping the construction party to take measures in advance to ensure construction quality.

[0050] The working principle of the above technical solution is as follows: Based on the earthwork volume, maximum diameter, minimum diameter and depth of the construction area in the real-time three-dimensional model, the first construction index (ZB) of the construction area is calculated using a given formula.

This index comprehensively reflects some geometric and earthwork-related characteristics of the construction area. The picture of the construction area is obtained and converted into a grayscale pixel matrix B. The average grayscale value (jz) and grayscale standard deviation (DE) of the matrix B are calculated using a given formula as the second construction index of the construction area. The average grayscale value reflects the overall brightness of the image, while the grayscale standard deviation reflects the degree of change in the image brightness. According to the first construction index (ZB) and the second construction index (jz and DE), the verification result (rt) of the construction process is calculated using a given formula. The formula combines the logarithm of the first construction index, the square term and the first-order term of the average grayscale value and the grayscale standard deviation, and is operated through an exponential function. The verification result (rt) is a value between 0 and 1, which is used to indicate the degree of compliance of the construction process. The verification result (rt) is compared with a preset threshold. If the verification result is greater than the preset threshold, it means that the construction process verification of the construction area has passed; otherwise, it means that the construction process verification has failed.

[0051] Beneficial effects of the above technical solution: The construction process verification module determines the verification result of the construction process by calculating the first construction index and the second construction index of the construction area and comprehensively evaluating the two indexes. This method combines information on the shape of the construction area, earthwork volume, image grayscale, etc., and can more comprehensively evaluate the compliance of the construction process.
