Abstract

本发明为一种形体三维线结构测示法,属于三维立体分析领域。目前,对于物体的结构形状的测示,多采用目测,凭人的感觉,如考古、人体解剖、文物等工作中。这样既不准确,又很困难。本发明的方法是利用光学仪器和界光面底片来形成一界光面空间,把待测物体置于其中,使界光面投影到物体上,并用记录仪将其记录下来。本方法可以广泛应用于考古学、人体解剖学、人类学、文物复制、雕塑等领域。

Description

形体三维线结构测示法
本发明为一种形体三维线结构测示法,属于三维立体分析领域。
目前,对于物体的形状结构的测示,多采用目测,凭人的感觉,用仪器也只能测量长宽高及有关角度。如对考古学中的人体骨骼测量、文物结构等。这样即不准确,又很困难。根本涉及不到形体的线面结构。
为了准确方便地对物体的结构进行分析,本发明物提出了一种形体三维线结构测示法。
本发明的形体三维线结构测示法是把界光面底片放于光学仪器的像位上(光学仪器指:幻灯机、放大机、投影仪等),使其投影在屏幕或墙壁上,在光学仪器的景深范围内形成一界光面空间;将待测物体放于界光面空间中,使得界光面投影到物体的表面上,形成物体表面的三维线条;用记录设备(如相机、摄影机、摄像机等)记录这些线条图像。然后就可以利用这些图像,对物体的结构进行直观的分析。界光面底片是带有条纹线或格栅线的底片。
采用本方法,可以很方便地得到物体的三维线结构,从而对物体进行直观的分析,以获得准确的物体形状结构。本方法可以广泛应用于考古学、人体解剖学、人类学、文物复制、雕塑等领域。
图1为本方法使用光栅型界光面底片测示人头像的实例图;
图2为单界光面底片;
图3为双界光面底片;
图4为经纬界光面底片;
图5为光栅型界光面底片。
实施列1:(见图1、5)
本发明的形体三维线结构测示法是把界光面底片(1)放于投影仪(2)的像位上,使光栅图像投影在屏幕(3)上,在投影仪(2)和屏幕(3)之间形成一界光面空间;将人头模型(4)放于界光面空间中,使得界光面投影到人头模型(4)的表面上,形成物体表面的三维线条(5);用相机(6)将人头模型(4)和其上的三维线条(5)拍照下来。然后就可以利用这些图像,对人头模型(4)的结构进行直观的分析。
实施例2:(见图4)
对于结构比较简单的物体可采用经纬界光面底片,方法同实施例1。
实施例3:(见图2,3)
对于结构较复杂的物体可采用单界光面或双界光面底片,方法基本同实施例1。只是在测示中需移动底片或投影仪,以便产生一组三维线条。
