Abstract: Object identification through image matching can utilize ratio and other data to accurately identify objects having relatively few feature points otherwise useful for identifying objects. An initial image analysis attempts to locate a “scalar” in the image, such as may include a label, text, icon, or other identifier that can help to narrow a classification of the search, as well as to provide a frame of reference for relative measurements obtained from the image. By comparing the ratios of dimensions of the scalar with other dimensions of the object, it is possible to discriminate between objects containing that scalar in a way that is relatively robust to changes in viewpoint. A ratio signature can be generated for an object for use in matching, while in other embodiments a classification can identify priority ratios that can be used to more accurately identify objects in that classification.

Abstract translation: 通过图像匹配的对象识别可以利用比率和其他数据来准确地识别具有相对较少的特征点的对象，否则对识别对象是有用的。 初始图像分析尝试在图像中定位“标量”，例如可以包括可以帮助缩小搜索分类的标签，文本，图标或其他标识符，以及提供用于 从图像获得的相对测量值。 通过将标量的维数与对象的其他维度进行比较，可以以对视点变化相对鲁棒的方式来区分包含该标量的对象。 可以针对用于匹配的对象生成比例签名，而在其他实施例中，分类可以标识可用于更精确地识别该分类中的对象的优先级比。
