摘要
针对近景影像直线提取算法中,EDLines和LSD算法的效果性能对比在国内期刊中未有明确论述这一情况,该文对直线提取效果进行目视判读,并联合直线匹配结果的正确率及其正确匹配数目两方面进行分析讨论,对这2种直线提取算法的性能予以评价。分别采用2种算法对不同类型近景影像进行直线提取及匹配实验,结果表明,针对近景影像直线提取,EDLines算法直线提取效果略优于LSD算法。
For close-range image,the comparison of the effect and performance of EDLines and line segment detector(LSD)line extraction algorithms have not been clearly discussed in domestic journals.In this paper,the effect of line extraction was visually interpreted,the accuracy of line matching results and the number of correct matches were analyzed and discussed.The performance of two line extraction algorithms was evaluated.The final experiment showed that EDLines algorithm had better performance.
