[0041] Example 1
[0042] A calculation method of asphalt pavement structure depth based on generalized regression neural network, such as figure 1 As shown, including the following steps:
[0043] S1. Specimen selection and image acquisition: prepare several groups of specimens with different gradations and number them, adjust the position of the industrial camera to make the target surface parallel to the horizontal plane, adjust the focal length of the camera to make the image clear, set the camera shooting frequency, and then The test piece is placed directly under the camera, and the digital image of the surface of the test piece is automatically collected and stored, that is, the image of the test piece. The test piece can be of asphalt concrete texture and includes at least 5 groups, each of which has three pieces. Each piece of asphalt concrete test piece The size is 300mm×300mm×50mm;
[0044] S2. Obtain the image of the specimen after sanding: the surface of the specimen s...
