【摘要】:為了優(yōu)化三維溫度場(chǎng)聲學(xué)CT重建系統(tǒng),對(duì)聲波路徑的合理選擇進(jìn)行了仿真研究.將20個(gè)聲波收發(fā)器布置在長(zhǎng)方體被測(cè)區(qū)域的周?chē)?分別考慮了4種聲波路徑選擇方式,保留了非重復(fù)的所有路徑、去除了長(zhǎng)方體棱邊上的路徑、去除了長(zhǎng)方體側(cè)面上的路徑和去除了長(zhǎng)方體表面上的路徑.用相對(duì)誤差、均方根誤差等指標(biāo),評(píng)價(jià)了溫度場(chǎng)的重建質(zhì)量.結(jié)果表明,聲波路徑的選擇方式對(duì)溫度場(chǎng)重建具有明顯影響.合理地選擇聲波路徑,可以降低聲學(xué)CT法溫度場(chǎng)重建的誤差和計(jì)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.
