Xunheng Jewelry automatic biaxial 3D scanner is a highly integrated automatic 3D scanning system developed by Beijing Xunheng Technology Co., Ltd. based on the desktop fine small workpiece (<100mm) 3D reconstruction application scenario design. In the hardware design, TI-DLP chip and image sensor chip are used for integrated circuit design, which greatly improves the communication efficiency and stability, and realizes 0.3 seconds high-speed scanning. The system supports multiple scanning, group splicing can realize one-click automatic global registration of point cloud, denoising and blending, lossless meshization, data optimization, and automatic generation of STL standard 3D format. It can be imported into mainstream jewelry design software, CNC machining systems and 3D printers. It is widely used in jewelry hand 3D auxiliary design, fine small workpiece 3D measurement.
