Embodiment 1

[0042] Please refer to Figure 1 to Figure 6 , a method for reconstructing incomplete foot bone fossils, comprising the following steps:

[0043]Step 1: Use CT to scan multiple modern human foot bones, convert the two-dimensional slice images of modern human foot bones obtained by CT scanning into BMP format, and perform image smoothing, image enhancement, image interpolation and image processing on the two-dimensional slice images in BMP format Segmentation preprocessing; compress the preprocessed two-dimensional slice images and perform nonlinear optimization and geometric fitting to obtain the fitting data, and perform data visualization calculation on the fitting data to construct a three-dimensional map of modern human foot bones. Store the constructed three-dimensional map of modern human foot bones as a point cloud;

[0044] Step 2: Establish the modern human foot bone body coordinate system based on the Euler axis of the constructed modern human foot bone three-dimens...

Abstract

The present invention relates to the field of anthropology, in particular to a method for reconstructing incomplete foot bone fossils, which creatively scans, positions and standardizes the surface geometry of modern human foot bones similar to primitive human foot bone fossils; The fossils were scanned, positioned, and surface geometry standardized, and the modern human foot bone model with the highest similarity was obtained through comparison. By superimposing the modern human foot bone model with the highest similarity and the original human foot bone fossil model, the modern human foot bone model In order to repair the incomplete part of the primitive human foot bone fossil by reference, repair the incomplete part of the primitive human foot bone fossil, make the repaired shape more realistic, and then restore the standardized repaired foot bone fossil to the real size in proportion, that is, Completed the reconstruction of incomplete foot bone fossils, obtained a complete foot bone shape, and provided a new method for the reconstruction of incomplete human fossils.

Description

technical field [0001] The invention relates to the field of anthropology, in particular to a method for reconstructing incomplete foot bone fossils. Background technique [0002] Fossils are biological remains or remains in rocks, and are the most direct morphological evidence of biological evolution. Every fossil is a miracle, because maybe only one in a billion living organisms will eventually become a fossil. For this reason, fossils are especially valuable for humans who are only a few million years old. The morphology of limb bone fossils can be used as direct anatomical evidence for the analysis of human motor function. For example, the shape of a fossilized talus bone suggests that our ancient ancestors may have been jumpers, not climbers. On the evolutionary tree, this feature separates the ancient ancestors of humans from the "Achilleus monkeys". [0003] The articular surface (joint head, joint socket) of the foot bone can not only reflect the structural relat...
