Background:

Distributed SLAM systems offer computational efficiency over centralized approaches.
Generic particle filters in SLAM suffer from particle impoverishment due to random prediction and resampling, especially in high-dimensional problems.

Purpose of the Study:

To improve the performance and robustness of particle filters within distributed SLAM (Simultaneous Localization and Mapping) systems.
To address particle impoverishment issues in high-dimensional SLAM applications.

Main Methods:

Enhanced the importance function of local filters using adaptive values instead of constants.
Proposed an information fusion method combining the innovation and effective number of particles methods.
Extended convergence proofs for particle filters to demonstrate convergence to the optimal filter in mean square.

Main Results:

The improved particle filter demonstrated enhanced robustness and fault tolerance in distributed SLAM.
The proposed fusion method effectively combined the strengths of existing techniques.
Experimental results validated the superior performance of the enhanced DPF-SLAM system.

Conclusions:

The developed particle filter improvements significantly enhance distributed SLAM system performance.
The system exhibits better tolerance to isolated faults and overall robustness.
The findings contribute to more reliable and efficient SLAM solutions.
