3D object modeling method based on depth sensor

Abstract

The invention discloses a three-dimensional modeling method of an object based on a depth sensor, comprising the following steps: S1, a data acquisition step of reading data from the depth sensor to obtain three-dimensional point cloud data; S2, a preprocessing step of separating the point cloud of the object from the whole scene, removing abnormal points, extracting the boundary of the point cloud of the object, and obtaining the point cloud of the object under each visual angle; S3, a point cloud registration step of registering an object point cloud under an adjacent perspective to obtain aconversion matrix between the object point clouds under the adjacent perspective; S4, a global alignment step of fusing the point clouds under each visual angle into the global point clouds by usinga conversion matrix to obtain a three-dimensional point cloud model; S5, meshing and texture mapping step, converting the three-dimensional point cloud model into a mesh model, and then mapping the color information to the surface of the mesh model to obtain a three-dimensional texture model. On the basis of guaranteeing the modeling accuracy, the method improves the modeling speed, and has high use and popularization value.

Description

technical field [0001] The invention relates to an object modeling method, in particular to a depth sensor-based object three-dimensional modeling method, which belongs to the field of three-dimensional modeling in computer vision. Background technique [0002] With the continuous development of computer vision technology, as an important branch of computer vision technology, 3-dimensional reconstruction (3-dimension Reconstruction) technology has been widely used in various fields and industries such as virtual reality (Virtual Reality), cultural relics protection, etc. It is foreseeable that in the future, 3D modeling technology will also be applied to Internet projects such as e-commerce, so that consumers can view products in all directions and bring more realistic user experience. However, due to the high price and slow scanning speed of professional 3D scanning equipment, there are still some difficulties in popularizing and applying 3D modeling of objects in people's ...
