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 reconstruction method of incomplete foot bone fossil. The method creatively scanning, positioning and carrying out surface geometry standardization for modern human foot bones similar to the fossilized bones of primitive human feet, p at that same time, the primitive human foot bone fossil is scanned, positioned and issubjected to surface geometry standardization, and the highest similarity of modern human foot model is obtained by comparison. By superposing the modern human foot bone model with the primitive humanfoot bone fossil model with the highest similarity, taking the modern human foot bone model as reference to repair the incomplete fossil part of primitive human foot, the method has the effects thatthe incomplete part of the primitive human foot fossil is repaired, the repaired model is more practical, and the standardized repaired foot fossil is reduced to the true size according to the proportion, that is, the reconstruction of the incomplete foot fossil is completed, the complete foot bone shape is obtained, and a new method is provided for the reconstruction of the incomplete human fossil.

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...
