摘要： There is provided a visual localization method comprising: providing access to a database that is maintained by: electronically storing a plurality of images in a database, wherein each of the stored images is associated with a location, and wherein each of the stored images is represented by a reference vector indicative of the frequency of visual words in the respective image; determining descriptors corresponding to visual features in the plurality of stored images; generating a binary search tree by quantizing the descriptors to obtain a plurality of visual words corresponding to nodes of the binary search tree, comprising: determining a hyperplane for each node to separate the child nodes of the respective node; and storing descriptors that are within a distance from the hyperplane of a node in an overlapping buffer associated with that node; for a given node, terminating the quantization when reaching a predetermined quantization threshold; the visual location method further comprising: receiving one or more video frames representing a query image of the location to be recognised; determining descriptors corresponding to visual features in the query image; quantizing said descriptors to obtain a plurality of visual words; and using an inverted file index to determine an image in the database that contains said visual words and the location associated with that image.
摘要翻译：提供了一种视觉定位方法，包括：提供对数据库的访问，所述数据库通过以下操作来维护：电子地将多个图像存储在数据库中，其中每个所存储的图像与位置相关联，并且其中每个所存储的图像被表示通过指示各个图像中的视觉词的频率的参考矢量; 确定与所述多个存储图像中的视觉特征相对应的描述符; 通过对所述描述符进行量化以获得与所述二叉搜索树的节点相对应的多个视觉词语来生成二叉搜索树，包括：确定每个节点的超平面以分离所述相应节点的子节点; 以及存储与与所述节点相关联的重叠缓冲器中的节点的超平面一定距离内的描述符; 对于给定节点，当达到预定量化阈值时终止量化; 所述视觉位置方法还包括：接收表示要被识别的位置的查询图像的一个或多个视频帧; 确定与查询图像中的视觉特征相对应的描述符; 量化所述描述符以获得多个视觉词; 并使用反转的文件索引来确定数据库中包含所述视觉词和与该图像相关联的位置的图像。
