非完全数据下的OCT重建研究

Research on the reconstruction of OCT with incomplete data

本文从理论和实践角度深入探讨了严重缺少数据情况下（如含遮挡物的复杂三维流场及有限观察角的情况）的三维重建问题，提出了充分利用待测场的先验知识，如数值计算的结果和部分实测值，采用信息融合的思想，改进重建理论，以实现在有限观察角并且含遮挡物的条件（如风洞）下进行重建。

In this paper,the reconstruction of three dimension flow field with incomplete projection data is researched on the aspects of theory and experiments.The incomplete projection data means that the opaque objectives exist in the flow field or the observation angle is limited.The prior knowledge is applied to improve the reconstruction.That is,the numerical simulation results and the measured point temperature are combined to modify the reconstruction,in order to reconstruct the flow field of wind tunnel,which belongs to the reconstruction of incomplete projection data.
