Currently, global digital security and independent innovation have become the dominant themes of the era. 3D scanning is no longer limited to single-object/space acquisition but has evolved into an integrated all-domain solution encompassing 2D graphic digitization, desktop precision 3D scanning, large-scale scene reconstruction, and embodied robot autonomous collection. Gaussian real-time rendering, spherical visualization, multi-mode intelligent fill light, and electric automated servo control have become standard features of high-end equipment, with modeling efficiency and texture restoration accuracy improved several times over traditional devices.

Artificial intelligence, GPU parallel computing, and Gaussian splatting real-time rendering technologies are advancing rapidly, propelling the global 3D scanning industry into the AI-driven intelligent era. AI-powered noise reduction, automatic texture mapping, and ultra-fast 3D reconstruction algorithms have significantly reduced modeling time. Spatial scanning now integrates inertial navigation and visual positioning to achieve seamless indoor-outdoor real-world replication. Device forms have diversified into three main categories: desktop precision object scanning, large-scale mobile spatial scanning, and portable handheld scanning.

With the improvement of computer processing power and the iteration of CCD imaging chips, optical photographic 3D scanning and mobile spatial SLAM scanning technologies have moved toward commercial implementation. Manufacturers, represented by leading European and American brands, have introduced lightweight desktop 3D scanners and handheld spatial scanning devices. 3D reconstruction algorithms have gradually matured, enabling the complete generation of point cloud 3D models of objects. Large-scale spatial scanning is widely applied in fields such as architectural BIM, ancient building surveying, and urban real-scene modeling.

The initial wave of global informatization emerged, with developed countries in Europe and America taking the lead in fundamental research on three-dimensional spatial digitization technologies. Based on the foundational principles of laser ranging and optical triangulation, research institutions developed the first-generation laser 3D scanners and single-point spatial ranging devices. These devices were bulky and had extremely high operational barriers, limiting their use to niche defense research scenarios such as aerial surveying and precision component inspection in military and aerospace applications.
