Problems solved by technology

[0004] Although there are already many methods for constructing 3D visualization models, there are still many inconveniences and shortcomings:

[0005] 1. At present, there is still a lack of modeling methods for primary structures such as highway slopes. Common modeling techniques can model structural components, but the modeling of slopes is still vague and the resolution cannot reach project requirements, and cannot provide assistance for project monitoring and maintenance;

[0006] 2. At present, the establishment of 3D visualization models is still in its infancy. If you want to obtain ideal resolution and display effect, you can only rely on obtaining a large number of pictures on the spot. The collection of a large number of pictures is not only a complicated process, but also a large workload, time-consuming and labor-intensive. It wastes manpower and increases the workload of image processing in the later stage. At the same time, due to the large number of images and the large amount of accumulated model data, the loading on the platform requires high server requirements, and the loading speed is too slow when browsing, which is not conducive to fast Check, the user experience is extremely poor;

[0007] 3. The currently established model is only a three-dimensional model of the shallow surface terrain. It cannot reproduce and display information such as the stratum structure, geological form, and underground layout of structures inside the slope. The model is simple and has little information.

This has brought great inconvenience to geologists. When consulting relevant information, it is necessary to cooperate with historical design data, relevant construction data and other complex graphics to understand the slope situation, and cannot provide assistance for engineering work.
