Embodiment 1

[0046] Embodiment 1, the method for performing data simplification in the production of paleontological fossil structure inner carving specimens, the steps are as follows,

[0047] ⑴. Carry out X-ray scanning of paleontological fossils, use the Spies package software to complete the 3D structure of the fossils, and obtain the three-dimensional data of paleontological fossil specimens; when saving, the system automatically saves them in VAXML format;

[0048] ⑵. Output STL format file, refer to figure 1 :

[0049] When exporting in STL format under Spiersview, be sure to keep all key structures for complete output. When saving to disk, the system will automatically save it in VAMML format. After the output is completed, press F2 to change the extension to STL; it can be read by other CAD software;

[0050] ⑶. Reorganize one of the STL format files, refer to figure 2 :

[0051] Use Geomagic Studio to reshape the mesh surface, first select all files under the import and expor...

Abstract

The data reduction method in manufacture of a paleontological fossil structure inter-carven specimen includes: (1) carrying out X-ray scanning on a paleontological fossil, completing three-dimensional (3D) forming of a fossil structure with the Spies software package to obtain 3D data of the paleontological fossil specimen; (2) outputting standard template library (STL) form files: under Spiersview, carrying out the outputting files in the STL form, making sure that all the important structures are retained and output completely, when saving files, the system automatically saving the files in the VAXML form, and after the output is completed, the expanded name of F2 is changed to be STL, namely the files can be read through other computer aided design (CAD) software; (3)-(11) reforming files in the STL form, reducing the number of points as far as possible, but controlling relevant parameters to prevent the files from deforming due to excessive simplification; (14) saving the files in the STL form; and (15) saving the files in a drawing exchange format (DXF) form. The data reduction method in the manufacture of the paleontological fossil structure inter-carven specimen enables mass production of paleontological fossil structure inter-carven specimens to be a practicable and reliable technical scheme.

Description

technical field [0001] The invention relates to a method software, in particular to a method for data simplification in the production of paleontological fossil structure inner carving specimens. Background technique [0002] Paleontology is the study of the remains of various organisms buried in rocks or indirect evidence of their lives during geological history. In nature, the undecomposed parts of organisms after death are buried by sand and formed fossils after a long period of geological action. Therefore, most of the evidence of ancient organisms is based on mineralized structures that are not easily decomposed. However, due to the influence of geological age, biological structures will change or even be replaced alternately by other minerals. At the same time, paleontological fossils are often closely connected with the surrounding ordinary rocks and covered by rocks. To study the paleontological mineralization structure, we must first understand whether its struct...
