一种融合运动和立体的视差与运动估计算法

An Algorithm for Fusing motion and Stereo to Estimate the Disparity and Motion

本文提出融合运动和立体的视差与运动估计算法。算法首先通过计算瞬时ＦＯＥ，实现对每个像素处位移的ＭＡＰ估计，计算关联置信度测量，然后利用位移估计从两图像序列之一计算相对深度图并导出能用于匹配两立体对图像序列的视差先验概率分布，使立体对的两图像序列匹配，确定３－Ｄ景物深度。算法可独立估计每个像素处的视差，不需关联的平滑假设。

his paper proposes an algorithm for fusing motion and stereo to estimate the dis-parity and motion.Our algorithm can compute a MAP estimate of the displacement at each pixel and an associated confidence measure by calculating the instantaneous FOE. Using the displacement estimates we calculate a relative depth map from one of the image sequences.Then this depth map is used to derive a prior probability distribution for disparity that is used in matching the two frames of stereo paris.This method is used to estimate the disparity at each pixel indepondently and does not need any assumptions about smoothness.
