AI Technical Summary
The indoor positioning accuracy of magnetic navigation AGVs in existing intelligent transportation sandboxes is insufficient, leading to inaccurate multi-vehicle collaborative actions and the inability to visualize their operating status.
By employing UWB beacons and vehicle-mounted anchor points in tandem, high-precision 3D positioning is achieved. Combined with a wireless communication module, location information is uploaded to the cloud platform in real time, forming a closed-loop control system that solves the problems of insufficient positioning accuracy and real-time pose reporting.
It achieves high-precision 3D positioning of AGV vehicles and full visualization of their operating status, ensuring the synchronization of multi-vehicle collaborative actions and the stability of the system, and improving the simulation realism and management efficiency of the intelligent transportation sand table.
