中文摘要: |
针对红外图像拼接存在速度慢、精度低的问题,将常用的几种可见光图像配准算法用于红外图像配准对比实验。选择其中
实时性和准确性较好的SURF算法进行优化改进,采用的方法是图像区域分块、阈值化处理和特征点匹配对两级筛选(筛选条件根据不同对象可实时调整)。在
不牺牲准确性的前提下,改进方法有效地提高了红外图像拼接的实时性。实验证明笔者提出的红外图像拼接改进方法的有效性。 |
英文摘要: |
Aiming at the the problem of slow speed and accuracy of infrared image mosaic,several commonly used visible image registration algorithms were
used in the contrast experiment of infrared image registration. The SURF algorithm with good real time and accuracy was selected,and the improved method was improved by the image
region block,the threshold processing and the two stage selection of the feature point matching (the filtering conditions can be adjusted in real time according to different objects). Without
sacrificing the accuracy,the real time performance of the infrared image mosaic was effectively improved. The experiment proves that the improved method of infrared image mosaic
proposed in this paper is effective. |
