Well-designed miniature camera, the center distance of the two cameras can be adjusted between 10~25MM. It is convenient to install the shell of various structures, move horizontally and vertically, and adjust the 3D imaging effect. The camera can be quickly and conveniently installed and integrated with the optical structure to form an integrated built-in 3D imaging system with outstanding imaging effect and stable system. Only one installation and debugging is required before leaving the factory, and the imaging effect will always be the same. Compared with the 3D imaging solutions of split external cameras of other brands, it takes a long time to debug before each use, and the 3D imaging effect cannot be guaranteed.
