Keyword位姿测量 点状目标 中心定位 自适应
Abstract本文以基于模型的单目视觉位姿测量为应用背景,针对视觉位姿测量过程中目标区域特征不断变化的特点,提出了一种图像中点状目标中心的自适应、高精度定位方法。在分析各种目标中心定位方法适用条件的基础上,定义了表示目标区域内灰度分布均匀性和区域形状误差的目标区域特征,并根据这些目标区域特征自适应地选择最佳的目标定位方法。实验结果表明,该定位方法由于集成了各种中心定位方法的优点,其定位精度明显高于其它中心定位方法。
Other AbstractIn the applications of model-based pose estimation in monocular vision, as for expanding areas of point targets, we presented an adaptive and highly accurate positioning method on the centers of point targets. Based on the analysis of various positioning methods on target's centers, we defined area features of targets which represented the uniformity in grey distributing and the error of area's shape. Besides, our method can select the optimal positioning method adaptively according to these area features. Experimental results showed that our method is superior to others in accuracy. That is because it integrated the advantages of other positioning methods.
