由针图重建深度图

Reconstructing a Depth Map from Needle Maps

  • 摘要: 本文描述了由针图重建深度图的方法.首先由一对强度图象构成针图.为此,利用由图象发射等式和表面平滑条件得到的两种限制构成迭代算法,由遮挡的边界提供边界条件和由几个特殊点给出有用的起始值,从而大大减少迭代次数.然后用所获得伪针图构成深度图.为获得较为理想的表面深度图,使用了迭代弛张方法.

     

    Abstract: This paper describes a method for reconstructing a depth map from intensity maps.First,needle maps are eonstrueted from a pair of intensity maps.In this process weconstruct an iterative algorithm using two kinds of constraints:one from the image-irradiance equations and the other from the smoothness eondition.In addition,wedepend on the occluding boundary to provide boundary conditions and a few specialpoints to supply helpful initial values.The second process construets a depth mapfrom needle maps obtained from the first process.Both processes employ an iterativerelaxation method to obtain target map.
