Embodiment Construction
[0036] The concrete image reconstruction method of the present invention, such as figure 1 As shown, the method includes:
[0037] The first step is to use medical CT or industrial CT to scan the section of the concrete specimen to obtain the two-dimensional tomographic image data of the static compression CT image of the concrete;
[0038] The second step is to use the three-dimensional reconstruction visualization technology to perform three-dimensional reconstruction on the concrete static compression CT two-dimensional tomographic image to generate a three-dimensional display image; the specific method is as follows:
[0039] Use the three-dimensional reconstruction visualization technology to reconstruct the two-dimensional tomographic image of the concrete CT, and use the ray projection algorithm to emit a ray from each pixel on the concrete static compression CT two-dimensional screen according to the direction of the set line of sight. Equidistant sampling is carried ...
