固体火箭发动机探伤图像包络线伪迹校正

Envelope Curve Artifacts’ Correction in SRM’s Tomographical Image

摘要:

对固体火箭发动机探伤图像中出现的包络线伪迹进行了相应的研究,介绍了滤波反投影算法,分析了探伤图像中包络线伪迹产生原因,提出了相应的解决方法。对相应方法首先进行了计算机仿真验证,然后进行了固体发动机探伤图像包络线伪迹校正实验研究,取得了理想的效果。

Abstract:

The envelope curve artifacts in SRM’s tomographical image was studied, and FBP reconstruction algorithm was introduced. The reasons that caused the envelope curve artifacts in SRM’s tomographical image were analyzed, and the corresponding solutions were provided. Then the computer simulation proved the method to be corrected and the test was done and an ideal result was obtained.
