| 英文摘要 |
| Animals and humans can quickly use the incomplete spatial information in the senses to locate their current
position and navigate to the target, providing a biological model for vector navigation in an unknown environment. Aiming
at the robustness problems of the large-scale spatial vector navigation method based on the continuous attractor model and
the remainder system, a large-scale spatial vector navigation method is proposed based on the oscillatory interference model
and the stepwise ambiguity determination method. The simulation results show that under the condition of 2% measurement
noise, this method can accurately calculate the position vector in a large-scale environment of 245 m*245 m* sin 60°, and
the calculation accuracy of the position in each dimension can reach within 1 cm, which effectively improves the robustness
of vector navigation in a large-scale space. |
