This paper uses a new visualization method. The goal is to improve the results of 3D image reconstruction. Firstly, the hardware architecture of the system is improved. The clock of the system is extended. The combination of CY25400 micro controller and CDCVF2510 micro controller greatly speeds up the detection speed. Then the key technologies such as image parsing module, image preprocessing module and 3D visualization module are studied. The visualization elements are fed back to the 3D image to realize virtual reconstruction. Finally, the conventional 3D imaging technology is used to complete the simulation and comparison test in the same scene. Experiments show that this method can obtain high 3D image reconstruction effect. The system can clearly show the edge area of the image, and can meet the requirements of users.
