Three-dimensional digital image acquisition method and equipment

Abstract

The invention discloses a three-dimensional digital image acquisition method and equipment. The three-dimensional digital image acquisition method specifically comprises the following steps: S1, early-stage preparation, S2, image acquisition, S3, rotary scanning of an object, S4, image algorithm processing, S5, three-dimensional reconstruction of an image, and S6, data transmission and consultation. In the three-dimensional digital image acquisition method and equipment, virtual reconstruction of cultural relics can be realized; the purposes of completing three-dimensional acquisition of images and carrying out three-dimensional reconstruction on partially damaged and incomplete cultural relics are well achieved; therefore, the acquisition of the completed image is realized; in addition, three-dimensional image acquisition and creation can be carried out on some cultural relics with partially incomplete or partially damaged textures, the application function of the three-dimensional image acquisition technology is greatly enriched, use of cultural relic research protection workers is greatly facilitated, and meanwhile low-light compensation can be carried out when cultural relic scanning three-dimensional image acquisition is carried out.

Description

technical field [0001] The invention relates to the technical field of image acquisition, in particular to a three-dimensional digital image acquisition method and equipment. Background technique [0002] Data acquisition refers to the automatic collection of non-electricity or electric quantity signals from analog and digital units under test such as sensors and other equipment under test, and sends them to the host computer for analysis and processing. Three-dimensional data acquisition refers to the use of a series of sensors or measuring equipment to measure Three-dimensional objects to be measured are used for data collection. With the development of aviation, aerospace technology and computer digital image processing technology, the cost of photogrammetry equipment has been greatly reduced. Digital photogrammetry has become the main means of large-scale and large-area measurement. After data processing, it can provide a wealth of geographical and spatial information. A...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a three-dimensional digital image acquisition method and equipment, which solves the problem that the existing three-dimensional image acquisition can only complete the image acquisition, but for some cultural relics with partial incomplete or partially damaged texture It is said that the virtual reconstruction of cultural relics cannot be realized, the purpose of not only being able to complete the three-dimensional acquisition of images but also performing three-dimensional reconstruction of partially damaged and incomplete cultural relics, and the application functions of three-dimensional image acquisition technology cannot be enriched
