Problems solved by technology

[0003] At present, the 3D model of cultural relics can be reconstructed by hand-held laser scanners and other related equipment, but this method is complicated to operate, the data processing cycle is long, and the equipment is expensive, which is not easy to promote
Specifically, hand-held laser scanners can obtain 3D point cloud data of movable cultural relics, but the work of pasting the point cloud in the later stage is time-consuming and the effect is poor
Even if some hand-held laser scanners can generate textures, it is often necessary to re-shoot digital images to paste textures due to low pixels

Abstract

The invention discloses a multi-perspective three-dimensional reconstruction method and device of a removable historical relic, and thus the three-dimensional reconstruction process of the removable historical relic can be simplified and the processing process is faster. The method comprises the following steps: obtaining two groups of images of a historical relic to be subjected to three-dimensional reconstruction, wherein one of the two groups of images need to be obtained together with a measurement control panel, the two groups of images are obtained by utilizing a camera to shoot the historical relic on different support benches at different places, when the first group of images of the two groups of images are shot, the top portion of the historical relic is not contacted with the support bench, where the historical relic locates, and when the second group of images of the two groups of images are shot, the bottom portion of the historical relic is not contacted with the support bench, where the historical relic locates; generating a part of dense point cloud of the historical relic according to the two groups of images; constructing a three-dimensional coordinate system according to a plurality of control points on the measurement control panel; merging the part of dense point cloud in the three-dimensional coordinate system to generate a dense point cloud of the historical relic; and reconstructing a three-dimensional model of the historical relic according to the dense point cloud of the historical relic.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a multi-view three-dimensional reconstruction method and device for movable cultural relics. Background technique [0002] With the passage of time and the impact of human activities, cultural relics are constantly being destroyed. How to digitally process cultural relics to realize their three-dimensional display is of great significance for spreading culture. [0003] At present, the 3D model of cultural relics can be reconstructed by hand-held laser scanners and other related equipment, but this method is complicated to operate, the data processing cycle is long, and the equipment is expensive, which is not easy to promote. Specifically, hand-held laser scanners can obtain 3D point cloud data of movable cultural relics, but the work of pasting the point cloud in the later stage is time-consuming and the effect is poor. Even if some hand-held laser scanners can generate texture...
