AI Technical Summary

Technical Problem

In existing technologies, user location detection methods based on wireless sensor networks have high requirements for signal strength and user hardware capabilities, resulting in inaccurate positioning and the inability to identify the location of some users, especially elderly users and special groups.

Method used

A binocular vision-based trajectory detection method is adopted. By acquiring depth images and bird's-eye view images, and combining depth cameras and wide-angle cameras, user identification and location recognition are performed. The user trajectory information is generated by matching with a pre-built pool of personnel information.

Benefits of technology

It improves the accuracy of user location, reduces the requirements for hardware and user capabilities, and enhances the user experience.
