基于非量测相片的三维模型重建

Three-Dimensional Model Reconstruction Based on Non-Measured Photo

摘要: 随着科技的发展，对视觉感受的要求提高，越来越多的三维影像产品进入生活，然而三维模型重建受到诸多限制，并未达到公众要求。近年来，用非量测相片进行三维重建成为三维模型重建的流行方式之一。本文主要介绍了使用非量测相片进行相机标定、特征点提取与匹配、极线约束与本征矩阵计算、三维重建、误差分析，最终完成三维模型重建的过程，并简要分析了此方法的应用前景。

Abstract: With the development of science, the requirement of visual feeling is improved, an increasing number of three-dimensional image products enter life. Nevertheless, the three-dimensional model reconstruction is subject to many restrictions, and does not meet the public requirement. In recent years, three-dimensional reconstruction with non-measurement photos has become one of the popular ways of 3D model reconstruction. This paper mainly introduces the process of 3D model reconstruction, including the use of non-measurement photos for camera calibration, extraction and matching of feature points, line constraint and intrinsic matrix calculation, three-dimensional reconstruction, error analysis. Lastly, the paper briefly analyzes the prospect of this method.
