Abstract

A method and a system for obtaining an object three-dimensional model are disclosed. The invention is applicable to the technical field of three-dimensional visualization and provides a method for generating a three-dimensional object model. The method comprises a step of obtaining the information of the color image and collected by a camera, a step of removing a plane and downsampling, a step of selecting a random sample point and a computer descriptor, a step of carrying out model preprocessing, calculating a model descriptor and filling the descriptor into a hash table, a step of determining a matching area of inputting 3D data and a 3D object model, a step of using the 3D model data to fill the missed and fuzzy points in the matching area, a step of using the 3D model data to extrapolate an area which can not be observed, and a step of obtaining a complete 3D model with high precision. According to the method and the system, the object three-dimensional model can be rapidly and automatically established, a known data structure is directly obtained, the subsequent analysis and measurement are facilitated, even a noise or partial scan information exists, a fully formed 3D model can be outputted always, and the method and the system are suitable for a moving object.

Description

Technical field [0001] The invention belongs to the technical field of three-dimensional visualization, and relates to a method and system for three-dimensional modeling of an object. Specifically, a depth camera is used to establish and reconstruct a three-dimensional model of an object based on a three-dimensional object template; it is widely used in digitization of cultural relics, biomedical imaging, and animation production. , industrial measurement, immersive virtual interaction, human-computer interaction, games, augmented reality, video surveillance, robotics, and the automotive industry. Background technique [0002] Three-dimensional object scanning and reconstruction is to obtain and analyze the shape (geometric structure) and appearance data (such as color, surface reflectance, etc.) of objects and environments in the real world, and use the obtained information to establish corresponding digital models in the virtual world. Existing 3D scanning equipment is com...
