Xunheng Handheld structured Light 3D scanner is a highly integrated and easy to operate handheld 3D scanning system designed based on real-time 3D reconstruction application scenarios developed by Beijing Xunheng Technology Co., LTD. In hardware design, TI-DLP chip and image sensor chip are used for integrated circuit design, which greatly improves communication efficiency and stability, and realizes 0.03 seconds high-speed scanning. In the software, the interactive dialog mode is highly coupled, which further simplifies the user operation process and reduces human-computer interaction. The global registration of point cloud is automatically completed with one key, denoising and blending, lossless grid, and STL standard three-dimensional format is automatically generated.
