A Real-Time High-Precision Pedestrian Navigation Method, Device, and Related Components

View on CNIPA website (Chinese)

This invention discloses a real-time dynamic high-precision pedestrian navigation method, device, and related components. The method includes:

1. obtaining the user’s starting position and target position in an indoor environment;
2. generating an optimal walking route containing at least one feature point based on the starting position and target position; while the user progresses along the optimal walking route, collecting the user’s displacement information;
3. and revising and optimizing the optimal walking route based on the displacement information until the user reaches the target position.

This invention generates the optimal pedestrian navigation route for users in indoor environments and adjusts and optimizes the navigation route based on the user’s displacement information, thereby improving the accuracy of indoor pedestrian navigation.
