【摘要】 二维物体的识别是计算机视觉与航空摄影测量领域里重要的研究目标。本文提出在图像预处理阶段运用边缘提取的算法和数学形态学先得到轮廓线，形成对特征的描述。基于这些特征描述建立了用动态规划法进行特征匹配的数学模型和算法。实验结果表明它不仅具有可靠性和稳健性，而且在计算机上易于编程实现。更多还原

【Abstract】 :Two-dimensional object recognition is an important task in the field of com puter vision and photogrammetry. This paper presents a new recognition ap proach by which the contour is obtained through the edge detection and the use of mathematical morphology in preprocessing stage, and then the descriptions of features are established. Based on it, the mathematical model and algorithm of feature matching via Dynamic Programming are established.The following expe riment demonstrates that the method proposed in this paper is not only dependable and robust, but also easy of computer programming.更多还原
