| 摘 要： | 为了快速精确提取图像角点,提出了一种基于预检测的SUSAN角点提取方法.文中首先采用预检测的方法排除部分伪角点,对预备角点采用SUSAN算法检测出图像的角点.然后采用图像分块技术和近邻角点排除方法来保证角点分布均匀,没有成簇现象,保证后续图像拼接的精度.实验结果表明,此方法不但能提高角点的检测速度,而且能合理地提取图像中的角点,提高角点的检测精度,进而提高图像拼接的速度和精度.

| Abstract: | In order to quickly and accurately extract image comers, A SUSAN comer detection method with pre-detection is proposed in this paper. At first, a corner pre-detection is used to extract candidate comer and reject false comers. Then, image block and neighboring point eliminating method is proposed to make the corners be well-proportioned distributing and avoid too many comers stay together effectively. The experiment shows that the method not only improve the speed of comer detection, but also improve the detection accuracy of the corners with reasonable extraction to the corners. It improve the image mosaic speed and accuracy. |
