Abstract

Three-dimensional (3D) reconstruction of shapes is an important research topic in the fields of computer vision, computer graphics, pattern recognition, and virtual reality. Existing 3D reconstruction methods usually suffer from two bottlenecks: (1) they involve multiple manually designed states which can lead to cumulative errors, but can hardly learn semantic features of 3D shapes automatically; (2) they depend heavily on the content and quality of images, as well as precisely calibrated cameras. As a result, it is difficult to improve the reconstruction accuracy of those methods. 3D reconstruction methods based on deep learning overcome both of these bottlenecks by automatically learning semantic features of 3D shapes from low-quality images using deep networks. However, while these methods have various architectures, in-depth analysis and comparisons of them are unavailable so far. We present a comprehensive survey of 3D reconstruction methods based on deep learning. First, based on different deep learning model architectures, we divide 3D reconstruction methods based on deep learning into four types, recurrent neural network, deep autoencoder, generative adversarial network, and convolutional neural network based methods, and analyze the corresponding methodologies carefully. Second, we investigate four representative databases that are commonly used by the above methods in detail. Third, we give a comprehensive comparison of 3D reconstruction methods based on deep learning, which consists of the results of different methods with respect to the same database, the results of each method with respect to different databases, and the robustness of each method with respect to the number of views. Finally, we discuss future development of 3D reconstruction methods based on deep learning.

摘要

三维形状重建是计算机视觉、 计算机图形学、 模式识别和虚拟现实等领域的重要研究课题. 现有三维重建方法通常存在两个瓶颈: (1) 它们涉及多个人工设计阶段, 导致累积误差, 且难以自动学习三维形状的语义特征; (2) 它们严重依赖图像内容和质量, 以及精确校准的摄像机. 因此, 这些方法的重建精度难以提高. 基于深度学习的三维重建方法通过利用深度网络自动学习低质量图像中的三维形状语义特征, 克服了这两个瓶颈. 然而, 这些方法具有多种体系框架, 但是至今未有文献对它们作深入分析和比较. 本文对基于深度学习的三维重建方法进行全面综述. 首先, 基于不同深度学习模型框架, 将基于深度学习的三维重建方法分为4类: 递归神经网络、 深自编码器、 生成对抗网络和卷积神经网络, 并对相应方法作详细分析. 其次, 详细介绍上述方法常用的4个代表性数据库. 再次, 对基于深度学习的三维重建方法进行综合比较, 包括不同方法在同一数据库、 同一方法在不同数据库以及同一方法对于不同视角个数输入的结果比较. 最后, 讨论了基于深度学习的三维重建方法的发展趋势.
