‍The auxiliary imaging technology of the laser engraving machine, the general 3D imaging technology, uses the graphics method to obtain 3D images. It is necessary to project a bright laser to measure the object. Through the distance of the laser beam, the image and model of the object are processed. The whole process is very Complicated. It takes multiple shots to obtain a 3D image of an object, which is expensive and slow, especially not suitable for capturing images of moving objects. The whole process sometimes takes tens of minutes, and the object cannot move during the shooting. This means that this photography technique can only be applied to landscapes and stationary objects.‍

Later, people invented the 3DFlash! photography technology, which has an absolute advantage in photographing the human body-high resolution can be obtained within 0.01 seconds, and accurate three-dimensional data of the human face can be obtained. 3DFlash! The three-dimensional flash can be connected with an ordinary two-dimensional digital camera to project a special grating code onto the surface of the object, and the digital camera captures the coded image. Through special decoding software, the coded image is analyzed to find out the 3D information of the X, Y, and Z axis of the image. In this step, the processed portrait is a 3D mesh portrait composed of a grid. The next step is to give a face Apply skin and color. After completion, a 360-degree 3D full avatar was created on the computer. The computer then inputs the information into the inner engraving machine, and then a perfect portrait inner engraving handicraft can be produced.

The combination of laser internal engraving machining system and computer numerical control technology can form high-efficiency automatic processing equipment, which opens up broad prospects for high-quality, high-efficiency and low-cost processing and production. The laser inner engraving machine is a high-tech integrated new laser peripheral processing equipment that combines laser technology and computer technology.

The laser internal engraving machine adopts high-performance laser and numerical control technology. Through the self-developed optical system, control system and computer software, it realizes three-dimensional dynamic precision laser engraving in crystal and glass, which solves the problem of slow engraving speed, unstable system work, and loss. Laser points have incomplete image and word processing software functions, the use of computer interface control cards, uneven laser explosion points, imperfect automatic control devices, and low cost-effective equipment. Comprehensively improve the efficiency, accuracy, maintainability, versatility and safety of the system.
