| 摘 要： | 针对移动机器人视觉图像间的连续特性，提出了一种基于小波模极大值的图像特征匹配算法，该算法利用小波模极大值提取图像轮廓及模方位矩阵，并在轮廓图像中寻找极大区域，以该区域中心点作为图像特征点，且将区域小波模方位、特征点区域图像重心坐标和区域轮廓重心方向组合生成这些特征点的特征向量，利用这些特征向量实现图像间的特征点匹配．并通过相应的实验证明提出的新算法高效可靠．

| Abstract: | By taking advantages of the sequential characteristics found between image frames from mobile robot vision,an image feature matching method is proposed based on wavelet transform modulus maximum.Starting with acquisition of image of interest and direction matrix of modulus by calculating the wavelet transform modular maximum,the maximum region of the image profile is thus obtained.The central points of the regions just obtained are set as the image feature points,with which the image vectors are created by ... |
