摘　　要：伴随立体影像直线特征提取技术的迅速发展,针对直线提取技术的综述性文章相对较少,且研究人员很难对其有较为全面掌握的情况。对国内外研究学者提出的立体影像直线提取技术进行了相对系统的概述与归纳。并且从直线特征提取的完整性、抗噪性、高效性和复杂性4个方面通过实验进行总结对比,结果表明,不断改进后的直线特征提取算法可以有效地削弱或者去除直线提取过程中的锯齿效应所带来的影响,从而可快速获取符合直线匹配要求的的线特征。因此直线特征作为立体匹配后续高级处理的基础,在影像处理和模式识别等领域的研究具有巨大潜力。Stereo image line feature extraction technology has also been rapid development,for the current line extraction technology review article is relatively small,and line feature extraction research methods are many,various methods are uneven,most researchers are difficult to have a more comprehensive grasp of the situation.The line extraction technology of stereo image proposed by scholars at home and abroad is systematically summarized.And this paper summarizes and compares the integrity,anti noise,efficiency and complexity of line feature extraction through experiments.The results show that the improved line feature extraction algorithm can effectively weaken or remove the influence of sawtooth effect in the process of line extraction,so as to quickly obtain line features that meet the requirements of line matching.Therefore,as the basis of stereo matching advanced processing,line feature has great potential in image processing and pattern recognition.
