| 摘 要： | 建立了基于小波变换的三维温度场重建的新算法.与传统的变换法和级数展开法相比,该算法不仅能分析信号的空间-频率特性,滤除噪声,而且能实现有限角重建,是一种实用性较好的算法.通过数值模拟计算,对小波变换法的重建效率和精度与SART及ART作了对比.

| Abstract: | Based on Wavelets base theory, a new approach to 3 D temperature field reconstruction is established. Compared with the traditional reconstruction approaches, Transform methods and Series expansion methods, the signal spatial frequency feature are not only analyzed, getting rid of the noise effectively, but also limited view reconstruction can be done. The reconstruction efficiency and accuracy of this method is contrasted with SART and ART through an analogous computation. |
