Embodiment Construction

[0065] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0066] The present invention provides a method for three-dimensional reconstruction of commodities, the method comprising:

[0067] S1. Obtain at least three point cloud images of commodities from different perspectives;

[0068] S2, based on the SAC-IA-ICP algorithm, register the point clouds of two adjacent point cloud images in all point cloud images to eliminate the offset between adjacent point clouds;

[0069] S3. Using an improved Poisson surface reconstruction algorithm to reconstruct a complete 3D surface model of the product from all the registered point clouds.

[0070] Optionally, in an e-commerce application, the above method may further include the following step S4.

[0071] S4. Use the lighting renderer to perform color rendering and lighting ...

Abstract

The present invention provides a three-dimensional reconstruction system and reconstruction method for a commodity. The method includes: S1. Obtaining at least three point cloud images of the commodity from different perspectives; S2. Based on the SAC-IA-ICP algorithm, two adjacent points in all point cloud images are The point clouds of the cloud image are registered to eliminate the offset between adjacent point clouds; S3, use the improved Poisson surface reconstruction algorithm to reconstruct a complete three-dimensional commercial surface model of all registered point clouds; S4, use The lighting renderer performs color rendering and lighting rendering on the product's three-dimensional surface model to obtain a displayable three-dimensional product model. The details of the three-dimensional product model constructed in the above method are more prominent, the geometric features are more obvious, the effect is more realistic, and the overall shape and detailed characteristics of the product are truly restored.

Description

technical field [0001] The invention relates to a computer vision and three-dimensional reconstruction technology, in particular to a commodity three-dimensional reconstruction system and reconstruction method. Background technique [0002] 3D reconstruction technology is a technology that digitizes actual 3D objects and reproduces them in the computer using computer technology. 3D reconstruction technology involves many disciplines, covering professional knowledge of computer graphics, computer vision, computer science, robotics, image processing, artificial intelligence and other disciplines. 3D reconstruction technology plays an important role in the fields of 3D commodity display, human-computer interaction, protection and restoration of cultural relics, augmented reality, reverse engineering, film and television entertainment, etc. [0003] As an active projection and non-contact depth sensor, Kinect is deeply loved by friends from all walks of life and researchers bec...
