AI Technical Summary

Technical Problem

Existing optical intelligent reflective surface systems suffer from problems such as mirror center offset, low array density, slow convergence due to reliance on codebook scanning, and communication delays caused by hardware and software separation.

Method used

The system employs a vision-based intelligent optical reflective surface system. It integrates the reflective panel and camera coaxially, rotates the center of the universal ball joint pivot, and uses a gear and rack differential transmission structure. Combined with a vision processing module, it achieves fixed center of the mirror and high-density deployment. It also uses a vision closed-loop architecture to replace traditional codebook scanning and 3D spatial optimization, and combines a PD anti-vibration closed-loop algorithm to eliminate mechanical vibration.

Benefits of technology

It achieves high-precision, ultra-low-latency continuous beam tracking, solves the communication delay problems caused by mirror center offset, low array density, reliance on codebook scanning, and hardware/software separation, and provides visible light communication capabilities in dynamic scenarios with strong anti-interference capabilities.
