[0003] The infrared thermal imager uses an infrared detector and an optical imaging objective lens to receive the infrared radiation energy distribution pattern of the target to be measured and reflect it on the photosensitive element of the infrared detector, thereby obtaining an infrared thermal image. This thermal image corresponds to the heat distribution field on the surface of the object; different colors of the thermal image represent different temperatures of the object to be measured, which can characterize the overall temperature distribution of the target to be measured; based on infrared photography, the level detection of the object needs a coal bunker level detection device to detect it; but the existing coal bunker level detection device generally cannot rotate the infrared camera structure to shoot, and it is necessary to set up multiple infrared camera structures at the coal bunker, which increases the detection cost and reduces the detection effect. In addition, it is generally impossible to adjust the angle of the infrared camera structure, and it is not easy to perform infrared thermal imaging at various places in the coal bunker, resulting in omissions in the level detection, which reduces the level detection effect. In addition, the equipment is generally fixed and installed by a bolt structure. Since it is not easy to install a fixing frame on the inner wall of the coal bunker, the installation process is more troublesome, which reduces the installation effect of the equipment.

[0034] Embodiment 3

[0035] See also Figures 2 to 4 The limit installation assembly 5 includes a rotating mouth 501, a guide plate 502, a sliding frame 503, a movable plate 504, a plug rod 505, a threaded sleeve 506, a rotating handle 507 and a threaded rod 508. Guide plates 502 are welded on the inner walls of both sides of the installation groove 4, and the sliding frame 503 is slidably connected to the guide plate 502.

[0036] First, place the installation frame main body 1 on the top of the coal bunker. At this time, rotate the rotating handle 507 through the rotating opening 501 to make the threaded rod 508 rotate. Then, under the action of the threaded sleeve 506, the threaded sleeve 506 moves in position, so that the sliding frame 503 on the moving plate 504 moves along the guide plate 502, and the insertion rod 505 on the moving plate 504 is inserted into the inner wall of the coal bunker to fix the position of the installation frame main body 1.

The infrared camera 2010 can be controlled through the control box 6 to perform composite enhancement on the infrared image of the infrared camera 2010. The process of infrared image composite enhancement is as follows:

[0039] S1 Pretreatment

[0040] S1.1 Denoising Processing

[0041] Due to the equipment characteristics, the infrared image is easily affected by thermal noise, which may lead to the loss of image details. First, perform denoising processing on the image.

[0042] Median Filtering: Remove salt-and-pepper noise through median filtering.

[0043] Select a 3×3 neighborhood window and calculate the median of the pixel values within this window as the new value of the central pixel.

[0044] I median (x,y) = median9({I(x ′ ,y ′ )∣(x ′ ,y ′ )∈N(x,y)})

[0045] This can effectively remove the noise in the image while retaining the edge information of the image.

[0046] S1.2 Gray Scale Transformation Enhancement

[0047] S1.2.1 Histogram Equalization

[0048] Infrared images with insufficient contrast have problems in displaying details. Therefore, histogram equalization is used to increase the contrast of the image, making the contrast between the target area and the background more obvious.

[0049] Histogram equalization: Adjust the grayscale values through the cumulative distribution function (CDF);

[0050] Perform a histogram statistics on the image, calculate the cumulative distribution function CDF, and then map the grayscale values of the original image to a new range through the following formula:

[0051]

[0052] This makes the grayscale range of the entire image more uniform, thereby enhancing the contrast;

[0053] S1.2.2 Contrast stretching

[0054] Assume that the grayscale value range of the image is I min and I max , and expand the grayscale values of the image to a new range [0, 255] through contrast stretching:

[0055]

[0056] This can significantly improve the contrast of the target area;

[0057] Highlight the target area by adjusting the brightness and contrast;

[0058] S1.2.3 Gamma transformation

[0059] Gamma transformation is a non-linear method for adjusting the image brightness, which can increase or decrease the brightness and contrast of the image;

[0060] Apply the following formula to each pixel value I(x, y) for transformation:

[0061] I gamma (x, y) = round(I enhanced (x, y) γ )

[0062] Generally, γ > 1 is used for brightness enhancement, and γ < 1 is used for enhancing dark details;

[0063] S2 Deep learning model design

[0064] S2.1 Network model selection: Pix2Pix

[0065] Pix2Pix is a model based on the conditional generative adversarial network (ConditionalGAN, cGAN), which is suitable for image-to-image conversion tasks; in infrared image target enhancement, it can take a low-quality infrared image preprocessed by traditional methods as input and generate a high-quality enhanced image; this model includes a generator and a discriminator, and its working principle is as Figure 5 shown;

[0066] S2.2 Generator

[0067] The generator structure of the Pix2Pix network is as Figure 6 shown; this generator uses an eight-layer U-shaped network structure, with eight convolutional layers and eight transposed convolutional layers respectively; the encoder adopts a structure of convolutional-Leakyrelu activation function at the lowest and highest layers, and adds BatchNorm in the middle of this structure to accelerate convergence and suppress overfitting; the decoder decodes the encoded feature vectors through transposed convolution;

[0068] S2.3 Discriminator

[0069] The discriminator adopts the PatchGAN structure, as Figure 7 shown; this structure not only avoids the computational waste of traditional algorithms on a large number of useless regions, but also can learn and capture local features of images more finely, effectively handle overall problems, and greatly improve the stability and accuracy of the structure;

[0070] S3 Result Fusion

[0071] S3.1 Feature Fusion

[0072] Fuse the image I gamma enhanced by the traditional method and the image I DL generated by deep learning with weights:

[0073] I fused = α·I gamma +(1 - α)·I DL

[0074] S3.2 Post-processing

[0075] Use the Sobel operator to enhance the edges of the fused image; the Sobel operator is often used for image sharpening and edge detection. It detects edge information by calculating the approximate first-order derivatives of the image gray values in the horizontal and vertical directions, and then highlights the contours and details of the image, making the image look clearer and sharper;

[0076] The Sobel operator performs convolution calculations in the horizontal and vertical directions respectively to obtain the gradient map of the image;

[0077]

[0078] Calculate the gradient magnitude:

[0079]

[0080] where, I x and I yThey are the gradients of the image in the x and y directions respectively;

[0081] The gray value of the fused image and the calculated gradient amplitude are weighted and summed according to a certain coefficient to obtain the gray value I after sharpening by the Sobel operator sharp (x, y), and the calculation formula is as follows:

[0082] I sharp (x, y) = I fused (x, y) + λ × G(x, y)

[0083] Where λ is the sharpening coefficient (which can be adjusted according to the actual situation, generally taking a small positive value, such as between 0.1 and 1), and the degree of sharpening is controlled by this coefficient to avoid unnatural effects on the image caused by oversharpening;

[0084] In this way, the edges in the image are enhanced, which helps to display the target area more clearly.

[0085] As described above, it is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
