Product function: This is an indoor, light-weight, hand-held navigation device that allows users to select their destinations by voice or manually and plan their navigation route automatically. The device can provide users with a highly accurate indoor Google Maps-like navigation experience.
Product performance advantage: The whole indoor navigation system can achieve centimetre-level high-precision positioning (accurate from 2-to 10cm). The device supports high capacity and high tag density with mass concurrency and no interference effects on the signal. It has low power consumption, with <1mA tag power consumption in sleep mode, which is 10% that of Bluetooth technology.
Product feasibility: The back end of the product is based on a 3D semantic map database, and it uses ultra-wideband (UWB) positioning technology. Its front end uses a voice interaction system and a touch screen operation function for human-computer interaction. The product supports multi-sensor fusion map information collection equipment, which uses VSLAM technology to fuse IMU, UWB information and image information to quickly and accurately build a 3D semantic map for of unfamiliar environments, accelerate the update of locating services in new scenes, and provide strong back-end support for locating services.
