炸点测试中多源数据融合技术研究

The Application of Multi-source Data Fusion to Blast Target Location

光电经纬仪测试炸点坐标时,由于多种缘故部分炸点目标不能被两个以上的测试站捕获到,从而导致数据录取率降低。文中针对该测试难题,提出了一种基于误差理论、点估计理论和证据理论的多源炸点测试数据融合模型,并将该模型成功用于声测炸点数据和单台光电经纬仪数据的融合,仿真表明该数据融合处理同时能获得较高的坐标精度。因此,该模型的应用有利于提高数据录取率,并保证测试精度。

When the photoelectric theodolite is used to test the burst point coordinate,in some tests,the data recording rate is not very high because some objects are not captured.Focused on the problem,in the paper,a multi-source test data fusion model was put forward based on error theory,point estimation theory and evidence theory,and also the model was successfully applied to the integration of the acoustic burst data and the single theodolite data to improve the data recording rate.The simulation results showed that good precision was achieved.
