Embodiment 1
[0051] The present embodiment is carried out in the computer Intel (R) Core2 T7200 2.0GHz 2G DDR2 running environment of 64-bit Windows 7 operating system, adopts MATLAB R2010a software to realize, take SMA-16 road surface as example, specifically realize by the following steps:
[0052] Step 1: Reconstruct the three-dimensional structure of the road surface, and obtain the three-dimensional structure image and three-dimensional coordinate values on the XYZ coordinates, accurate to 0.0001mm; see figure 1 and figure 2 ,specifically is:
[0053] Step 1.1: Adjust the camera and light source, and use the camera to obtain a two-dimensional image of each of the red, green, and blue light sources on the test road surface; The height of the unit and the light source is 1m from the road surface; adjust the irradiation angle and brightness of the red, blue, and green light sources so that the irradiation areas are completely overlapped, and the synthetic light is white; adjust the r...
Embodiment 2
[0084] In step 2, the square grid is divided into a size of 0.001 mm*0.001 mm, and other steps in this step are the same as in embodiment 1.
[0085] Other steps are the same as in Example 1.
Embodiment 3
[0087] In step 2, the size of the square grid is divided into 1 mm*1 mm, and other steps in this step are the same as in embodiment 1.
[0088] Other steps are the same as in Example 1.
