索引技术通常用于基于模型的目标识别和光线跟踪算法。在本文中,我们提出了一种新的方法来估计的三维位置的一个主题(分别。对象)在基于索引方法的外接空间中。我们构造了一个空间的二维和三维索引,这些索引用于通过插值技术来估计三维位置。在估计对象的三维位置中存在两个过程(分别是:对象):预处理和三维位置估计。我们已经实现了这个想法,使用立体相机,并测试了使用两种不同大小的网格图案。预处理和三维位置估计的前景。此外,我们表明,这种方法也可以扩展到多个相机。关键词:索引空间,网格模式,三维位置估计,插值
Indexing techniques usually are used in modelbased object recognition and ray tracing algorithms. In this paper we present a new method for estimating the threedimensional position of a subject (resp. object) in a circumscribed space based on an indexing method. We construct two and three-dimensional indices of a space, which are used to estimate the three-dimensional position by an interpolation technique. There are two processes in estimating the threedimensional position of a subject (resp. object): preprocessing and three-dimensional position estimation. We have implemented this idea using stereo camera, and tested by using two different sizes of a grid pattern. Promising results for preprocessing and 3D position estimation are presented. Moreover, we show that this approach can also be extended for multiple cameras. key words: indexed space, grid pattern, 3D position estimation, interpolation
