Computational ghost imaging (CGI) can build a three-dimensional (3D) image using the reconstructed shading images. However, it could be easily affected by the noise accumulated in the 3D reconstruction. More importantly, the selection of initial growing position will also affect the quality of the formed 3D image significantly. In this paper, we apply the technique of sub-pixel displacement to achieve smooth shading images in noisy environments and propose a method for selecting the optimal initial growing position to preserve the stereo feature of the object. We demonstrate that the surfaces of the reconstructed 3D images are more accurate using our proposed method as compared to the ones achieved by previously used methods. Our research would promote the development of 3D imaging using CGI in noisy environments.
计算鬼成像（CGI）可以使用重建的阴影图像构建三维（3D）图像。然而，它很容易受到三维重建中累积噪声的影响。更重要的是，初始生长位置的选择也将显著影响所形成的三维图像的质量。在本文中，我们应用亚像素位移技术在噪声环境中获得平滑的阴影图像，并提出一种选择最佳初始生长位置的方法以保留物体的立体特征。我们证明，与先前使用的方法相比，使用我们提出的方法重建的三维图像表面更精确。我们的研究将推动在噪声环境中使用CGI进行三维成像的发展。
