立体视觉中的三目匹配方法研究

RESEARCH ON TRINOCULAR MATCHINGMETHODS FOR STEREO VISION

  • 摘要: 本文提出了利用金字塔图传播匹配的三目基元立体视觉方法.该方法中匹配起始三元组的选择建立在透视投影的可靠基础之上,而进行传播匹配可以加速计算,并避免了可能的误匹配.传播匹配利用立体图像组在二值边界图像金字塔图中的结构相似性,而整个匹配结果的考察与认定是通过传播率的比较实现的.该方法能够有效地克服双目立体视觉方法的某些本质局限性,确保匹配结果精确可靠.

     

    Abstract: In this paper a trinocular stereo vision method using pyramidal graph propagation matching is proposed. The choice of the starting triplet in the algorithm is based on perspective projective geometry and matching through propagation greatly limits the searching scope. Therefore, it can accelerate the computing and avoid the possible false targets. Matching through propagation makes use of the structural similarities of stereo triplet images in pyramidal graphs of BLI's, whereas the overall examination and verification of matching results is done by a comparison of the propagation success ratio. This algorithm can effectively overcome some essential limitations of binocular stereo vision methods and assure the matching results precise and reliable.
