AI Technical Summary

Technical Problem

Existing indoor positioning technologies have shortcomings in terms of accuracy, real-time performance, deployment cost, and adaptability, especially in complex indoor environments where they struggle to meet the demand for high-precision real-time positioning.

Method used

A multimodal indoor positioning method integrating radio frequency and machine vision is adopted. By combining monocular ranging with three levels of data fusion (raw level, feature level, and decision level), the advantages of wireless signals and visual features are combined, and a hierarchical decision algorithm is used to adapt to the needs of multiple scenarios, ensuring the adaptability of the positioning method in different environments.

Benefits of technology

It effectively compensates for the shortcomings of single-modal positioning in complex environments, achieves high-precision real-time positioning, adapts to the needs of multiple scenarios, and improves the adaptability and accuracy of positioning methods.
