An effective method for retrieving 3D models is to represent and discriminate them with their 2D images projected from multiple viewpoints. Such view-based methods conform more closely to human visual recognition for 3D model retrieval, since the human retina essentially captures 2D images. However, most of the existing view-based methods do not take into account that different views have different...
The purpose of reverse engineering is to convert a large point cloud into a CAD model. In reverse engineering, extracting geometric parameters of quadric surfaces from measured data is an important problem. It helps to understand the designer's intent, and improves accuracy and efficiency of parts reconstruction. In this paper, an improved genetic algorithm with real valued genes and an adaptive mutation...
