The methods to digitse and reconstruct the shapes of complex 3D objects have evolved rapidly in recent years.The speeds ang accuracy of digitizing technologies owe much to advances in the areas of phsice and electrical engineering,including the development of lasers,CCDs,and high speed sampling and timing circuitry.Such technologies could allow taking detailed shape measurements with precision better than 1 part per1,000 at at rates exceeding 1,000 saples per second.To capture the complete shape of an object,many thousands,sometimes millions of data geometry points(X-Y-Z coordinates)must be acquired.
The standatrd methods for extracting range data from optical scaaners are accurate only for planar objects of uniform reflectance.Using these methods,curved surfaces,discontinuous surfaces,and surfaces of varying reflectance cause systematic distortions of the rangs data.When using coherent illumination such as lasers,however,the laser speckle places a fundamental limit on accuracy fo

对 将资料数字化的方法而且近几年来重建复杂 3D立体物体的形状已经快速地进展。数字化技术的速度 的准确性更加对电机工程的区域进步亏欠,包括抽取样品的激光、电压耦合元件和高速的发展和时间安排电路
如此的技术可以允许用比 1个每 1,000 部份好的精密拿详细的形状测量在比率非常的每秒 1,000 saples。为了要取得物体的完全形状,许多数千,有时数以百万计的数据几何学点 (X-Y-Z 的坐标) 一定被获得
吸取来自光学的范围数据的方法是正确的只有为统一反射比的平面物体。使用被弯改变反射比的表面，不连续的表面和表面的这些方法引起有系统扭曲那呜响数据。当使用互相密合着的照明，像是激光的时候，然而，激光小的斑点为传统而时空三角测量放一个基本的界限在准确性上。
范围数据普遍藉着 3D立体 digitisers ，像是光学的三角测量扫描仪获得有深度在一个 regulat 格子上抽取样品,样品组知道如范围 inage。因为藉由整合团体范围重建表面描绘，一些技术已经被发展。
。给如此的运算法则的一令人想要组的财产包括:逐渐增加的更新、方向不确定的表现,能力填充缝隙在那再在露宿者和扭曲之前的工程、和强健。使用这些方法学一能够无缝地合并一个合并很多的范围图像, 集合为迅速的用工具工作 (RT) 的发展被做模型的高细节.
