Solution Overview

Problem

Existing tracking systems with a single device often fail to achieve satisfactory pose tracking performance when parts of the object are occluded by obstacles, and deploying multiple devices introduces complexity in determining which devices to use effectively.

Innovation Solution

A method and device manager that generates a shared map from local maps of multiple tracking devices, determines pose ambiguity status, and disables tracking functions of specific devices with low performance to optimize resource usage and improve overall tracking accuracy.
