摘要
随着科学技术的发展和图像信息的大量产生和交流,对于目标图像的识别和自动处理也得到了越来越广泛的应用。同时在实际问题中(如水下自主航行器的导航与定位),计算机自动识别技术是不能满足实际应用的需求的。因此,要识别图像上的明显目标,并进行后续操作,必须先对图像中所存在的一些特征信息进行提取。图像特征提取是图像研究领域一个重要的研究方向,也是图像识别技术的基础。本文研究了图像的特征点的提取,图像的边缘提取和直线提取,并在此基础上研究了图像的特征在导航技术上的一些应用。
With the development of scientific and technological and a large number of production and exchange of the image information, the target image recognition and automatic processing has been more and more widely usage. While in practical problems(such as the navigation and position of autonomous underwater navigation device), computer automatic identification technology can not meet the needs of practical application. Therefore, in order to identify an obvious target for the image, and subsequent operations, some of the features present in the image information must be extracted. Image feature extraction is an important research direction the image field of study, and is also the basis of image recognition technology. This paper studies the extraction of feature points of the image, the image edge extraction and line extraction. And studies the characteristics of the image in some applications of navigation technology.
