Three-dimensional cultural relic reconstruction system and three-dimensional cultural relic reconstruction method based on computer stereo vision

Abstract

The invention relates to a three-dimensional cultural relic reconstruction system and a three-dimensional cultural relic reconstruction method based on computer stereo vision. The system is composed of a computer, a rotating platform, a digital camera and a camera support. The method comprises the steps of firstly inputting a cultural relic image into the computer, extracting feature points of the image, and establishing a matching relation; then carrying out multi-view reconstruction according to the feature points and the matching relation, and acquiring three-dimensional data of the cultural relic; and finally, carrying out texture mapping on the three-dimensional data of the cultural relic by adopting a Poisson equation, and outputting a textured three-dimensional cultural relic model. The beneficial effects lie in that (1) the method provided by the invention is simple and low in cost, and does not need additional control equipment; (2) the system provided by the invention is simple to use and convenient to operate, people only need to put the cultural relic on the rotating platform and presses a start button, and the system can output the texture indicating three-dimensional cultural relic data; and (3) the reconstruction efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a three-dimensional cultural relic reconstruction system and method based on computer stereo vision. Background technique [0002] Currently, there are two main types of technologies that can realize 3D reconstruction. The first type of technology is to use an instrument equipped with a depth measurement device (such as an infrared rangefinder, a laser rangefinder) to achieve 3D reconstruction such as Figure 1-2 As shown, for example, there are large-scale 3D scanners for modeling large scenes, and there are also depth cameras for small scenes. The advantage of this type of technology is its high precision, but its disadvantages are high cost, not easy to carry, and limited application range. The second type of technology uses a simple two-dimensional image as input, and uses an algorithm to achieve the purpose of restoring the three-dimensional structure of the target. The ba...
