摘要

摘要: 为突破矿井工人指纹定位中1维模型在定位精度上的局限性，该文提出一种矿井工人2维指纹定位数据库构建算法，并通过SVR-Kriging插值法解决因2维模型带来的数据采集工作量大的问题。首先，通过高斯滤波对采集的采样点位置指纹信息进行预处理，并利用支持向量回归由采样点数据拟合变异函数。然后采用Kriging插值法补全2维网格划分中的未采样区域的位置指纹信息。最后综合采样点与插值点的位置指纹信息建立矿井工人指纹信息数据库，为后续矿井工人指纹定位奠定基础。仿真结果表明，该文算法在减少数据采集工作量的同时保证了算法的可行性与有效性，且在进行位置指纹定位时能够保证较高的精度。

Abstract: In order to overcome the limitation of one-dimensional model in accuracy of mine workers fingerprint location, a two-dimensional fingerprint location database algorithm for mine workers is proposed. The problem of the large data acquisition workload brought by the two-dimensional model is also solved by SVR-Kriging interpolation. Firstly, Gaussian filtering is used to preprocess the fingerprint information of the collected sampling point and the variation function is fitted by the Support Vector Regression (SVR). Then, the Kriging interpolation is used to complete the position fingerprint information of the un-sampled area in the two-dimensional meshing. Finally, the fingerprint location database of the mine workers is established by integrating the location fingerprint information of the sampling points and the interpolation points, laying the foundation for the follow-up mine workers fingerprint location. The simulation results show that the proposed algorithm can reduce the workload of data acquisition while ensuring the feasibility and the effectiveness of the algorithm and can guarantee high accuracy when positioning is performed through the location fingerprint.
