摘要 图像立体匹配的精度是保证双目系统测量准确性的重要因素,也是系统研制过程中需要解决的难点问题。对影响双目系统中图像立体匹配精度的随机噪声建立了一种局部统计量符合高斯分布的简化统计模型,基于这个噪声模型设计了滤波方案。实验表明,滤波后图像立体匹配的精度优于1/4像素。 The stereo matching accuracy of image pairs is an important factor for ensuring measurement accuracy in binocular system and is also a difficult problem that is to be solved in system development process. A simplified statistic model that its local statistic accords with Gaussian distribution is established for the random noise affecting the stereo matching accuracy of image pairs in binocular system. A filtering scheme is designed based on the noise model. The experiments show that the stereo matching accuracy of image pairs after filtering is better than 1/4 pixel.
