摘要：

This paper presents a convenient method allowing ordinary people to quickly make 3D models of small objects, using only a mobile phone and computer. First, we capture a number of images around the object, and then quickly calculate the internal and external parameters of each image, and semi-automatically extract contours of the object using graph cuts, and finally generate a digital 3D model using the information from the object contours. The theoretical precision of the method is discussed in relation to a simulation experiment, and then the validity of the method is verified through a real experiment. The method in the paper can be used on static objects composed of different materials, and can solve the 3D reconstruction problem where image-matching or LiDAR fails. This method solves the robust SFM problem with a suitable background, and reduces the calculatiion costs through algorithm optimization. ©, 2015, Wuhan University. All right reserved.
