基于图像序列的特定建筑物识别算法

An Algorithm of Special Building Recognition Base on Image Sequence

本文提出了一种识别特定建筑物,并进一步与数据库存放图像进行匹配从而得到相应位置信息的算法.算法采用霍夫变换进行直线检测并计算消失点来进行建筑物存在性预判,进而提取SIFT特征进行图像匹配获取位置信息.直线检测、消失点检测和SIFT特征在本文提出的算法中发挥主要作用.

This paper presents an algorithm. This algorithm can recognize a special building,and further match the image which stored in the database,and obtain the corresponding location information. Hough transform can provide the existence of anticipation of building by line detection,and then extract SIFT features for image to match,and obtain location information. Line detection,vanishing point detection,and SIFT features play the main role in the proposed algorithm in this paper.
