发布时间：2018-12-20 21:59
【摘要】：为了优化三维温度场声学CT重建系统,对声波路径的合理选择进行了仿真研究.将20个声波收发器布置在长方体被测区域的周围,分别考虑了4种声波路径选择方式,保留了非重复的所有路径、去除了长方体棱边上的路径、去除了长方体侧面上的路径和去除了长方体表面上的路径.用相对误差、均方根误差等指标,评价了温度场的重建质量.结果表明,声波路径的选择方式对温度场重建具有明显影响.合理地选择声波路径,可以降低声学CT法温度场重建的误差和计算量.
[Abstract]:In order to optimize the three dimensional temperature field acoustic CT reconstruction system, the reasonable selection of acoustic path is simulated. The 20 acoustic transceivers are arranged around the measured area of the cuboid, and four acoustic path selection methods are considered respectively, and all the paths that are not repeated are preserved, and the paths on the edges of the cuboids are removed. The path on the side of the cuboid and the path on the surface of the cuboid are removed. The reconstruction quality of temperature field is evaluated by relative error and root mean square error. The results show that the selection of acoustic path has a significant effect on the reconstruction of temperature field. Reasonable selection of acoustic path can reduce the error and calculation of temperature field reconstruction by acoustic CT method.
