Description

Technical Field

[0001] The present invention relates to the field of building construction, and more particularly, to a building construction safety monitoring system. Background Art

[0002] Image filtering, i.e., suppressing the noise of a target image while preserving the image's detailed features as much as possible, is an indispensable operation in image preprocessing. The quality of its processing effect will directly affect the effectiveness and reliability of subsequent image processing and analysis. Generally speaking, when the signal spectrum and the noise spectrum are aliased or when the signal contains non-additive noise (such as noise caused by system nonlinearity or non-Gaussian noise), traditional linear filtering techniques, such as Fourier transform, will always blur image details (such as edges) in some way while filtering out the noise, thereby reducing the positioning accuracy of linear features and the extractability of features. Nonlinear filters are based on a nonlinear mapping relationship of the input signal, and can often map a specific noise to zero approximately while retaining the main features of the signal. Therefore, they can overcome the shortcomings of linear filters to a certain extent. Prior art CN102067600A provides a method and device for using local adaptive filtering for motion compensation interpolation and reference picture filtering. The device includes an encoder (100) for encoding picture data. The encoder (100) includes at least one local adaptive filter (150) for performing local adaptive filtering for at least one of reference picture filtering and interpolation filtering on picture data.

[0003] At present, construction sites are relatively complex due to the need to carry out various construction projects, and the equipment and personnel are relatively complex. When conducting safety monitoring, the picture content corresponding to the internal environment of the construction site is different at different times. As a result, if the same filtering algorithm is used to perform the same filtering processing on the picture content corresponding to the internal environment of all construction sites, the final picture obtained is often not of the most optimized quality. Therefore, it is necessary to find a filtering algorithm that can obtain the best picture quality for the picture content corresponding to the internal environment of the construction site at different times. Summary of the Invention

[0004] In order to solve the technical problems in the prior art, the present invention provides a construction safety monitoring system, which can compare the noise reduction ratio values ​​corresponding to various filtering algorithms to obtain the filtering algorithm corresponding to the maximum value, and apply the filtering algorithm corresponding to the maximum value to the geometric correction image to perform filtering processing to obtain an optimized filtered image corresponding to the geometric correction image, thereby achieving the optimal filtering effect for the geometric correction image. At the same time, only when the total number of employees currently staying in the target construction site is non-zero, the environmental sensing mechanism is triggered to perform the sensing action of the internal environment of the target construction site to obtain the corresponding construction site environment picture, thereby reducing unnecessary power consumption waste.

[0005] According to the present invention, a construction safety monitoring system is provided, the system comprising:

[0006] The gate control mechanism is used to, while releasing each employee entering the target construction site, accumulate the number of employees entering on that day and decrement the number of employees leaving on that day to obtain the total number of employees currently remaining in the target construction site;

[0007] an environment sensing mechanism connected to the gate control mechanism, and configured to sense the internal environment of the target construction site to obtain a corresponding construction site environment image when the total number of employees currently staying in the target construction site is non-zero;

[0008] A sequential mapping mechanism includes a first mapping unit, a second mapping unit, and a third mapping unit, wherein the second mapping unit is connected to the first mapping unit and the third mapping unit respectively, and the first mapping unit is connected to the environment sensing mechanism. The first mapping unit is used to perform Butterworth low-pass filtering on the received construction site environment image to obtain and output a corresponding content-filtered image. The second mapping unit is used to perform horizontal sharpening and vertical sharpening on the received content-filtered image in sequence to obtain and output a corresponding direction-sharpened image. The third mapping unit is used to perform geometric correction on the received direction-sharpened image to obtain and output a corresponding geometrically corrected image.

[0009] a ratio resolution mechanism connected to the sequential mapping mechanism, configured to collect the resolution of the received geometrically corrected image, the number of pixels occupied by the background image region, and the color channel values ​​corresponding to the pixels in the geometrically corrected image, and input the binary value of the algorithm code corresponding to the current filtering algorithm, the resolution of the geometrically corrected image, the number of pixels occupied by the background image region, and the color channel values ​​corresponding to the pixels in the geometrically corrected image into a convolutional neural network that has completed multiple learning cycles to obtain a noise reduction ratio value obtained by outputting the geometrically corrected image using the current filtering algorithm;

[0010] a numerical detection mechanism connected to the ratio resolution mechanism, for comparing the noise reduction ratios corresponding to the various filtering algorithms to obtain the filtering algorithm corresponding to the maximum value;

[0011] The content conversion mechanism is connected to the numerical detection mechanism and is used to apply the filtering algorithm corresponding to the maximum value to the geometrically corrected image to perform filtering processing and obtain an optimized filtered image corresponding to the geometrically corrected image.

[0012] The construction safety monitoring system of the present invention has a compact structure and intelligent design. By comparing the noise reduction ratios corresponding to various filtering algorithms, the filtering algorithm corresponding to the maximum value is applied to the geometrically corrected image to perform filtering processing, thereby obtaining an optimized filtered image corresponding to the geometrically corrected image. This achieves the optimal filtering effect for the geometrically corrected image. Furthermore, the system triggers sensing of the construction site environment image only when the total number of employees currently present at the target construction site is non-zero, thereby reducing unnecessary power consumption.
