A system and method for digital three-dimensional reconstruction of objects based on raster scanning

Abstract

The invention discloses an object digitized three-dimensional reconstruction system based on raster scanning. The object digitized three-dimensional reconstruction system based on the raster scanning comprises a management unit, a data collection unit, a data processing unit and a three-dimensional reconstruction unit. The management unit controls the work of the data collection unit, the data processing unit and the three-dimensional reconstruction unit. The data collection unit is used for collecting all-around image information of an object and transmitting the collected image information to the data processing unit. The data processing unit receives the image information and carries out denoising and compensation processing on the image information. The processed image information is further transmitted to the three-dimensional reconstruction unit. The three-dimensional reconstruction unit carries out position and direction calibration on the processed image information, the three-dimensional geometric structure of the object to be reconstructed is calculated by utilizing grating coding, and color texturing and material recover are carried out. Fine reconstruction of the object is carried out by utilizing the raster scanning equipment and software, and perfect revivification of the object on fineness, color and material aspects is achieved.

Description

technical field [0001] The invention relates to a system and method for digital three-dimensional reconstruction of an object based on raster scanning. Background technique [0002] Physical appearance digitization technology has a wide range of applications in many fields. For example, in the concept of the digital museum that we are familiar with, virtual art treasures will be presented in the digital network world, so that ordinary audiences can experience the same or even deeper art appreciation at home or near home, making the exhibition hall more humanized services without the objective limitations of time and space and even personal economic conditions. At the same time, physical digitization technology will have great application potential in industries such as computer games, digital movies, physical simulation, social networks, automobiles, cultural souvenirs, and home decorations. The application prospect of digital 3D modeling technology is very broad. It can b...

AI Technical Summary

Problems solved by technology

[0009] 1. The current scanners are mostly imported products, and the personnel who provide this service are only users, not technical professionals, and cannot solve practical problems in the collection process and results;

[0010] 2. The scanning time is long, and changes in the external environment will cause instability in the results;

[0011] 3. The collection process needs to calibrate the feature points on the object. This contact scanning method is not suitable for dealing with precious cultural relics;

[0012] 4. It requires a lot of heavy manual post-processing, which not only introduces artificial uncertain factors into the reconstruction results, but also greatly increases time and labor costs;

[0013] 5. Laser scanners are expensive and have no color information

The color needs to be manually rendered in the later stage; the most important thing is that the result of this method of acquisition and reconstruction does not have the texture information of the object material, but only the appearance geometric information
