Employing a two-axis scanning design and innovatively utilizing threshold-based sampling waveform digitization technology, this device achieves exceptional high-precision scanning while lowering implementation costs. It can perform panoramic scanning within mid-range scenarios (<100m) and achieve a high ranging accuracy of 4mm@10m. Consequently, this equipment finds applications in building information modeling (BIM), smart logistics, and security, providing users with more precise 3D data support.
