[0040] S104: Segment the image into road and non-road areas based on the grayscale thresholds of the road and non-road areas in the image, and represent the identified road and non-road areas as a second binary image, wherein the pixels of the road area in the second binary image are marked as 1, and the pixels of the non-road area are marked as 0.
[0041] S105: Perform fusion processing on the first binary image and the second binary image to obtain a fused image with fusion marks:
[0042] When the same position in both images is marked as a road, the same position is determined as a road in the fused image;
[0043] When the same position in the two images is the background, the same position is determined as the background in the fused image;
[0044] When the first binary image and the second binary image have different marks at the same position, the pixel at the same position is taken as the target pixel in the preprocessed image, and the grayscale co-occurrence confidence C of the target pixel in the preprocessed image is calculated. GLCM and grayscale threshold confidence CThre Compute and compare:
[0045] If C GLCM >C Thre , the same position in the fused image adopts the marking result determined by the first binary image,
[0046] If C GLCM ≤C Thre , the same position in the fused image adopts the marking result determined by the second binary image;

[0057] S301: Apply the Sobel operator and apply a 3x3 Sobel kernel to each pixel in the 7x7 square window to calculate the horizontal gradient value Gx and the vertical gradient value Gy of each pixel in the 7x7 square window.
[0058] S302: The gradient amplitude Gxy of the i-th pixel in the 7x7 square window is calculated as:
[0059]
[0060] Where Gx(i) is the horizontal gradient value of the i-th pixel in the 7x7 square window, Gy(i) is the vertical gradient value of the i-th pixel in the 7x7 square window, i = 1, 2, 3...49,

[0064] There are 25 3x3 sub-windows with different positions in the 7x7 window. The standard deviation SS of each 3x3 sub-window in the 7x7 square window is calculated:
[0065]
[0066] Among them, Gra(m) is the gray value of the mth pixel in the 3x3 sub-window, u is the average gray value of all pixels in the 3x3 sub-window,
[0067] S305: Calculate the average ALS of the standard deviations of all sub-windows:

[0073] The present invention significantly improves the ability of the autonomous driving vehicle to distinguish the road ahead and the surrounding environment in complex environments by innovatively combining the edge detection of the Sobel operator and the texture analysis of the gray-level co-occurrence matrix. It not only realizes the efficient fusion of edge and texture information at the algorithm level, but also optimizes the data processing flow by fine-tuning the weights of local and global features, thereby enhancing the accuracy and robustness of image recognition.
[0074] Embodiment 3: Combining with Figure 1 , Attachment Figure 2 and attached Figure 3 In addition to the contents of the above embodiments, the identification module implements the following steps:
[0075] S401: Scan the fused image, wherein each pixel position in the fused image recognition is represented by a coordinate position (x, y), wherein x represents a horizontal coordinate value, and y represents a vertical coordinate value. The coordinate origin (0,0) of the fused image is at the lower left corner of the image, and the bottom row in the fused image is the first row. The position of the kth row in the fused image corresponds to the position of the k+1th row, which is the area ahead of the car.
[0076] S402: Determine the positions of the left and right boundaries of each row in the fused image. The left boundary L(k) of the k-th row and the right boundary L(k) of the k-th row in the fused image are determined as follows:
[0077] L(k)=min[x|M(x,y)=1],
[0078] R(k)=max[x|M(x,y)=1],
[0079] min[x|M(x, y)=1] represents the value x corresponding to the coordinate position of the first pixel marked as 1 from left to right in the kth row of the fused image.
[0080] max[x|M(x, y)=1] represents the value x corresponding to the coordinate position of the last pixel marked as 1 from left to right in the kth row of the fused image.
[0081] S403: Obtain the left boundary movement amount ΔL(k) in the fused image:
[0082] ΔL(k)=L(k+1)-L(k),
[0083] S404: Obtain the right boundary movement amount ΔR(k) in the fused image:
[0084] ΔR(k)=R(k+1)-R(k),
[0085] S405: Calculate the left boundary moving average LShift of a preset number of rows M in the fused image:
[0086]
[0087] S406: Calculate the right edge moving average RShift of a preset number of rows M in the fused image:
[0088]
[0089] S407: When LShift>left curve threshold Tleft, it is determined that the road ahead of the tricycle is a left curve.
[0090] If RShift>right curve threshold Tright exists, it is judged that the road ahead of the tricycle is a right curve.
[0091] Tleft and Tright are determined by evaluating a large amount of historical data using the neighborhood technology and statistical analysis to determine the initial thresholds, and further field tests are conducted to collect boundary movement data under left-curve and right-curve driving conditions. The initial thresholds are optimized and dynamically adjusted by support vector machines, decision trees and / or deep learning models to obtain Tleft for judging left curves and Tright for judging right curves.
[0092] In this embodiment, those skilled in the art can refer to the above value examples and make adjustments according to actual conditions. In short, the specific value ranges and trends of the above Tleft, Tright, W1, W2, W3, W4, and W5 will be determined by the designer or operator of the processing system according to the actual electromagnetic measurement processing requirements and system response, and will not be repeated here.
[0093] The present invention can identify the curve condition of the road ahead of the three-wheeled vehicle, and adjust the vertical spacing of the vehicle's front wheels through an intelligent control system to optimize the stability and safety of the vehicle driving on the curve, so that the system can not only accurately analyze the boundary movement in the fused image and realize real-time curve recognition, but also dynamically adjust the height configuration of the vehicle to adapt to different driving environments. By automatically adjusting the spacing between the front wheels and the vehicle body, the system effectively controls the tilt of the vehicle body, reduces the risk of rollover, enhances the outer side stability during turning, and improves the safety and efficiency of the three-wheeled vehicle during driving.
