Problems solved by technology

[0009] However, the above two spatial data alignment methods rely entirely on visual observation and human judgment in terms of the correctness of the judgment of feature point pairs, the accuracy of operating the mouse pointer, and the rationality of the distribution of selected feature point pairs. The observation and judgment of personnel are different, it is difficult to guarantee the accuracy of alignment, and the work is time-consuming and laborious, which seriously affects the quality and efficiency of 3D digitization of cultural relics

Embodiment Construction

[0037] The following is attached Figure 1-2 The application is described in further detail.

[0038] refer to figure 1 , the embodiment of the present application discloses a three-dimensional scanning and photogrammetry integrated control device, which includes multi-layer frames 1 arranged in sequence in the vertical direction, several support rods 2 are arranged between adjacent two-layer frames 1, and several The four support rods 2 are evenly distributed along the circumference of the frame 1 and are fixedly connected to the adjacent two-layer frames 1 . It is easy to understand that the number of layers of the frame 1 depends on the size of the cultural relics to be measured, and those skilled in the art can determine the number of layers of the frame 1 according to needs, for example, it can be any desired number of layers such as 4 layers or 6 layers.

[0039] The same number of target balls 3 and image-controlled two-dimensional codes 4 are arranged on each layer o...

Abstract

The invention relates to a three-dimensional scanning and photogrammetry integrated control device and method, and belongs to the technical field of three-dimensional scanning. In the control method, firstly, three-dimensional scanning is conducted on the control device, and an initial target data file and an initial two-dimensional code image control data file are generated; three-dimensional scanning is performed on cultural relics and the control device, current sphere center coordinate data are generated, and the cultural relics and the control device are photographed after scanning is completed; coordinate transformation parameters are calculated according to the current sphere center coordinate data of the target sphere and the initial target data; and according to the coordinate transformation parameters, the initial coordinates of the image control two-dimensional codes are transformed and are used for photogrammetry data processing for automatic image control, so that a photogrammetry grid model is aligned with a three-dimensional scanning grid model. According to the integrated control device and method provided by the invention, automatic alignment of the three-dimensional scanning data and the photogrammetry grid model is realized, and the precision and the working efficiency of three-dimensional digitization of the cultural relics are improved.

Description

technical field [0001] The present application relates to the technical field of three-dimensional scanning, in particular to an integrated control device and control method for three-dimensional scanning and photogrammetry. Background technique [0002] Three-dimensional digital processing of cultural relics is an important means to carry out cultural relics research and cultural popularization. Three-dimensional digital cultural relics can obtain the texture model of cultural relics. The texture model consists of a grid model and a texture map. The grid model expresses the spatial information of cultural relics and is used to present the shape of cultural relics; the texture map expresses the color information of cultural relics and is used to present the visual characteristics of cultural relics. [0003] The texture model of component cultural relics mostly adopts the method of combining three-dimensional scanning and photogrammetry. Three-dimensional scanning can obtai...
