Research on 3D Model Reconstruction Method Based on Smart Phone

摘要: 三维重建一直是计算机视觉中的重要的研究领域，这是突破现有数字计算机的信息处理能力，将其扩展为能处理多维信息的重要途径之一。针对三维模型重建成本高、操作繁琐、周期长等问题，提出了一种基于智能手机的三维模型重建方法。利用智能手机拍摄物体，通过计算相机内部参数和目标物体的三维信息，生成物体表面的密集点云数据，并根据点云数据建立三维模型。最终以三维激光扫描结果为基础对模型进行分析评价。实验结果表明，该方法可以快速建立高精度的三维模型，具有简单、高效的特点，可应用于各个领域。

Abstract: 3D reconstruction has always been an important research field in computer vision, which is one of the important ways to break through the information processing ability of the existing digital com-puter and extend it to multidimensional information. Aiming at the problems of high cost, cumber-some operation and long cycle of 3D model reconstruction, a 3D model reconstruction method based on smart phone is proposed. Using the intelligent mobile phone to shoot the object, the dense point cloud data on the surface of the object is generated by calculating the internal parameters of the camera and the three-dimensional information of the target object, and a three-dimensional model is established according to the point cloud data. The experimental results show that the method can quickly establish a high-precision 3D model, which is simple and efficient, and can be applied to various fields.
