| 摘 要： | 提出一种基于图像分割和可信点的双目移动机器人立体匹配算法,首先采用纹理检验分割算法对双目移动机器人获得的左右图像进行分割,确定低纹理和纹理相似区域;然后通过SIFT特征匹配点得到可信点视差;其次采用SAD区域匹配加速算法得到初始视差;最后依据SIFT特征匹配点的分布、初始视差和最小距离分类器对图像分割块进行视差处理,同时对于较小的图像分割块进行BLOB滤波处理来获取较高精度的视差图.实验结果表明,本算法能有效解决双目移动机器人周边环境中的低纹理和纹理相似视差精度差的问题,可快速准确识别障碍.

| Abstract: | A novel stereo matching algorithm for a binocular mobile robot is presented,which is based on image segmentation and reliable point correspondences.Firstly,less and similar texture regions of stereo images are determined by the segmentation of the right and left image using the texture features verifying and segmentation;Then,the disparity of reliable point could be obtained by SIFT features point matching.Secondly,the preliminary disparity could be obtained by SAD area-based matching.Finally,the image is p... |
