3D Shape Estimation from RGB Data Using 2.5D Features and Deep Learning

Creation of 3D models from a single RGB image is challenging problem in image processing these days, as the technology is in its early development stage. However, the demands for 3D technology and 3D reconstruction have been rapidly increasing nowadays. The traditional approach of computer graphics is to create a geometric model in 3D and try to reproduce it onto a 2D image with rendering. The major aim of the study is to create 3D models from 2D RGB image using machine learning techniques to be less computationally complex as compared to any deep learning algorithm. The proposed model has been based on three different modules such as: 2.5D features extraction, mesh generation, and 3D boundary detection. The ShapeNet dataset has been used for comparison. The testing results has shown an accuracy of 90.77 % in the plane class, 85.72% in the chair class, and 72.14% in the automobile class. The proposed model could be applicable to problems where reconstruction of 3D models is required such as: variations in geometric scale, mix of textured, uniformly colored, and reflective surfaces.
